Reach for the best dehumidifier on the market and you might expect it to tackle everything from damp walls to dusty shelves. But the reality is a little more nuanced. While a dehumidifier is a genuinely powerful tool for improving indoor air quality, its relationship with dust is indirect and understanding the difference could save you money and a lot of frustration.

The culprit behind most dust-related allergies is not the dust itself, but the microscopic droppings left behind by dust mites – creatures that depend on humidity to survive. That is where a dehumidifier enters the picture. To find out exactly how, we asked three air quality experts to explain where dehumidifiers help with dust and where they fall short. Here is what they told us.

Does a dehumidifier help with dust?

The short answer is: not directly. A dehumidifier does not filter or hoover dust out of the air. What it does is remove excess moisture and in doing so, it dismantles the humid environment that allows dust mites and mould to thrive.

"A dehumidifier is not going to suck dust out of your air," explains Sam Carter, radiator and dehumidifier expert at Appliances Direct. "What it does is tackle the environment that lets dust mites and mould settle in the first place. Dust mites don't drink water – they absorb moisture from the air – so when you drop the humidity of your home they shrivel up and stop breeding."

Chris Michael, co-founder of Meaco, echoes this. "A dehumidifier's job is moisture control," he explains. "Most models include a basic dust filter, but it mainly protects the machine by catching larger particles before they reach internal components – it isn't there to clean your air. However, by reducing humidity, it helps reduce the conditions in which dust mites and mould thrive, which can reduce allergen build-up over time."

At what humidity level do dust mites and mould become a problem?

If you want to use a dehumidifier effectively against dust mites, it's important to know the ideal humidity for your home.

“Dust mites thrive when the relative humidity of your house is over 60%,” says Sam Carter. “So, set your dehumidifier to target 45–50% humidity, and this will make it dry enough to shut down mite breeding and to stop mould in its tracks – but not so dry that you’re waking up with static hair and cracked lips.”

Chris Michael adds that the UK climate plays a significant role. “During prolonged periods above around 65% relative humidity, conditions become much more favourable for dust mites and mould growth,” he warns, “especially in cooler rooms and areas with limited airflow and daylight such as bedrooms, bathrooms, corners and behind furniture.” Many UK households, he says, aim for around 50–55% RH as a practical target for comfort and damp control.

But there is such a thing as too dry. Push humidity too low and you create a different problem entirely. According to Noel Fok, co-founder of EcoAir, overly dry air irritates the throat and worsens symptoms for people with existing respiratory conditions – making 40% RH the floor, not just a guideline.

Can a dehumidifier help with allergies or asthma?

For the millions of people in the UK living with dust allergies or asthma, the good news is that a dehumidifier can genuinely help. The key is knowing what it actually does. It removes the conditions dust mites need to survive, which tackles the problem at its source. What it cannot do is clear the allergens already circulating in the air around you.

Once humidity settles at a healthy level, Noel Fok explains, allergens will gradually become inactive and stop posing a threat. Just be careful not to overcorrect. Air that is too dry can irritate the throat and nasal passages, which may end up making allergy symptoms worse rather than better.

If you want to go a step further, it is worth looking at models with integrated HEPA filtration. As Chris Michael points out, these work on two fronts, controlling humidity while also trapping airborne particles. So, for anyone serious about managing allergies at home, they are well worth considering.

Dehumidifier vs air purifier: Which one do you need?

If dust and allergens are your main concern, you may find you need an air purifier rather than a dehumidifier – or at least an understanding of how the two differ. Because while both can improve how your home feels, they work in very different ways.

"Unlike a dehumidifier, an air purifier actively cleans the air of existing airborne allergens by capturing them in a filter as air passes through," explains Noel Fok. "But the two can work very well together – one prevents the proliferation of allergens, the other purifies the air of those already present."

In practice, the best starting point comes down to your biggest bugbear. Struggling with condensation on your windows or damp patches on the wall? A dehumidifier should be your first port of call. If it is more a case of sneezing fits, pet dander or seasonal pollen making life miserable indoors, an air purifier with a true HEPA filter will likely make a more noticeable difference, more quickly. And if your budget stretches to both, running them in tandem is the most thorough approach of all.

When a dehumidifier won’t help with dust at all

A dehumidifier is not always the answer and knowing when to reach for something else (or simply the vacuum) can save you both money and frustration.

If your indoor humidity already sits in a healthy range, running a dehumidifier harder will not make a dent in your dust levels. And if the root cause has nothing to do with moisture – pet dander, carpet fibres, pollen drifting in through an open window – then humidity control is largely beside the point. "Those allergens don't care about humidity," says Sam Carter, "they just need a source and some breeze."

Settled dust is a whole other matter. No appliance, however powerful, will lift dust from your shelves or skirting boards. "Once it's sitting there, no machine is going to suck it up," Sam points out. "You need to vacuum – preferably with a HEPA machine, so you're not just blasting it back into the air."

The dehumidifier takes care of what is airborne and moisture-driven. Everything else still comes down to a good old-fashioned clean.

If you've spotted ice forming on your dehumidifier's coils, our guide to why your dehumidifier is freezing up is the first place to look. Getting the right model for your home's temperature range – and keeping on top of a few simple dehumidifier maintenance habits – should stop it from happening again.

But if your dehumidifier has started making strange noises or just isn't performing the way it used to, it might be worth checking how long dehumidifiers typically last. Sometimes, an upgrade is simply the most sensible solution.

My partner has yet to finish his new build garage, built specially to house his pride and joy. Meanwhile, I was itching to use this new space to get rid of some clutter from the house, which is a very small, two-bedroom cottage.

But while my partner has added electric underfloor heating to the garage floor (apparently cars need such luxuries), he has yet to finish off the electrical work to connect it up and heat the space. This means the garage is very cold, raising the risk of stored items (and his car) becoming damaged by condensation, damp and mould while the weather is dank outside.

So when I was given the opportunity to test the Meaco DD8L pro desiccant dehumidifier I jumped at the chance. I wanted to see if this was the best dehumidifier to keep my stored items damp and mould free, while my partner was salivating at the thought of potentially giving his car optimum climate-controlled conditions.

Practicalities of using a dessicant dehumidifer in a cold space

It's important to understand why I chose to test this Meaco DD8L pro desiccant dehumidifier in a cold garage, rather than inside the main house.

When it comes to desiccant vs compressor dehumidifiers, desiccant dehumidifiers work better in colder spaces because they operate by absorbing moisture from the air with a desiccant material. Compressor dehumidifiers meanwhile use refrigerant to cool coils inside them so moisture can be removed from the air via condensation. For this condensation to occur, there needs to be a noticeable difference in coil temperature and room temperature, hence why compressor dehumidifiers tend to work better in warmer spaces like inside the house.

That said, a desiccant dehumidifier still needs a minimum temperature threshold of 1°C to make sure the machine doesn't freeze up. Given the lack of underfloor heating in the newbuild garage, to solve the problem for testing, I added an oil-filled radiator to the space to make sure the temperature was always higher than freezing.

Unboxing the Meaco DD8L Pro

The Meaco DD8L pro desiccant dehumidifier arrived in a smart cardboard box that was well-packed, with protective inserts to stop the contents moving around and getting damaged.

The machine itself had a dust cover over it, meanwhile the information booklets on how to use the dehumidifier were easy to find when opening from the top. There was a large ergonomic indentation at the back of the machine for lifting the dehumidifier out of the box.

This particular model was fairly large so I would say it had a reasonable weight to it, but it was very easy to pull out of the box, even with the dust cover on it.

First impressions

The Meaco DD8L pro desiccant dehumidifier has all the hallmarks of a workhorse of a machine. And that's exactly what I needed for a large double bay garage with a concrete floor.

It has a decent 2 litre water collection tank, as well as having the option for continuous drainage, handy in a space that doesn't see regular footfall.

What's a nice touch with this particular dehumidifier is that it looks slick, with a dark top to it, so no dirty fingermarks show on areas where someone might be pressing buttons. It is fairly bulky owing to its 58cm x 36cm x 23cm dimensions, but this is to be expected if the machine is to be powerful enough to control humidity in larger spaces.

A smart-looking machine is of course ideal in a posh garage beside a fancy car. It might have been fun to be able to customise it in red to match the vehicle but, sadly, I don't think any dehumidifier offers this option.

What is cool about this particular machine though, is that it can be wall-mounted with the bracket designed by Meaco for this machine, making it ideal for space-saving in smaller garages. There's also a cable tidy on the back of the machine to hide away any unsightly wires when not in use. And, if you do decide to leave it on the floor, you can also buy separate castors on the Meaco website to be able to easily wheel it about.

Ease of use

Any dehumidifier will need to be left for 48 hours after delivery before attempting to turn it on. With compressor models this is to make sure compressor oil and refrigerant settles, much like a fridge, while desiccant dehumidifiers have a rotating desiccant wheel inside that also needs time to settle to avoid damage on start-up. You can read more this and how dehumidifiers work in our explainer on the topic.

Once I had waited, I plugged the Meaco DD8L pro desiccant dehumidifier in and pressed the "on" symbol. This was easy to find, to the bottom left of the control panel.

Immediately, the dehumidifier whirred into action, displaying the humidity reading of the room on the screen. Without having to adjust any settings, there was a clear indication of '55%RH' as the target room humidity setting it was aiming towards.

Despite a desiccant dehumidifier being ideal for colder spaces, I initially plugged in this dehumidifier inside the house so I could get a feel for the controls, before putting it into position beside the super car in the garage.

Overall, having used dehumidifiers before, I found this dehumidifier very easy to start up and use. It was literally one button to press after being connected to an electric source, before it started up and got to work instantly.

Using the control panel

The Meaco DD8L pro desiccant dehumidifier is impressively easy to operate, but does still have wide functionality. If you want a simple start, all you need to do is press the 'on' button after plugging it in and it will roar into action, with a target humidity reading of 55%RH, which is what you would usually want for normal humidity in a house.

Meanwhile, if you wanted to use this dehumidifier for laundry, you can easily press the T-shirt button to crank up the humidity setting to 35%RH which will whip more moisture from the air.

For my purposes in the garage, I found the ability to toggle between power settings very useful. I was able to set it at a low wattage with a slow fan speed to use minimal electricity. This was ideal for leaving the dehumidifier permanently on, controlling the humidity of the space at all times. Once its target humidity is reached – or the water tank is full – the dehumidifier also has an automatic shut off.

I loved that this dehumidifier had a germ and bacteria extraction setting too. While the new build garage doesn't have any damp or mould, I can see this being useful in older spaces. I have a damp wall in my house, and I often worry about airborne mould spores and bacteria around that space. Knowing my dehumidifier is removing these is added piece of mind.

Here's an overview of what all the different buttons on the DD8L do:

• On/off button. Turns the dehumidifier on or off. You'll find when you turn the dehumidifier off, it asks you to wait before unplugging the machine so it can cool down. This is little annoying, but I guess a helpful feature to avoid unintended damage.
• Large waterdrop button. Operate smart humidity mode by pressing this button once and automatically targeting a humidity setting of 55%RH. Pressing this button multiple times meanwhile will change the humidity to any required level.
• Small triple waterdrop button. Allows you to select the power of the dehumidifier and its fan speed. Select one drop for low fan speed and 200 watts of power, two drops for medium fan speed and 400 watts of power, and three drops for high speed fan and high power of 600 watts.
• T-shirt button. Pressing this button will activate smart laundry mode, giving the dehumidifier a target humidity setting of 35%RH. Press the smart humidity button (the large waterdrop) to stop laundry mode.
• Half-moon button. Press this button to activate night mode and child lock. This makes the dehumidifier much quieter by reducing the fan speed, fixing the louvre open, stopping the buttons from beeping and turning the lights off the display. Press the button twice to exit night mode.
• Clock button. You can switch a timer on with this button to make the dehumidifier start up at a specific time, or make it stop at a specific time.
• ++ and - symbol button. This is the ioniser and should be turned on when you want the dehumidifier to extract germs and bacteria from the air, as well as mould spores, odours and, apparently, ticks (yes really, apparently ticks become airborne and 'fly' through the air using static electricity to suck your blood). When this is on, it will show this same icon on the control panel.
• Louvre button. Operate the louvre on the top of the machine to either a fixed open position, or moving across a narrow, medium or wide position. The angle of the louvre will then display on the control panel.

Using the DD8L pro with a phone

I was looking forward to testing this dehumidifier on the Meaco app as it wasn't something I had done before. There wasn't much in the instruction manual about doing this, but a google-search found this YouTube video explaining how to set the dehumidifier up on the Meaco app.

After registering on the app, I went on to "add device". Both your dehumidifier and your phone need to be on the same WiFi network for this to be successful, and you need to know your WiFi password (a bit of a faff but I eventually found it). If this doesn't work, you can also follow the instructions to add the machine manually, but you'll still need to know your WiFi password.

I found using the dehumidifier with the app useful, mainly as it flagged when the water tank was empty, meaning I didn't need to keep checking in person. The app also tracked the humidity level in the garage, which allowed me to see how much work the dehumidifier was putting in to maintain the climate.

Overall the app was useful, but not essential, which probably is exactly what it should be.

Emptying the water collector

I've been using dehumidifiers a while and usually the removal of the water tank is a bit cumbersome, heavy to lift and fiddly to put back in. Generally you find access to the water tank is from the front, but the DD8L has a water tank that you pull out from the side.

This side-opening tank turned out to be much less cumbersome, and it even had a handle for carrying the tank to a sink for emptying. I was pretty impressed actually, perhaps because I've found them so annoying to handle in the past.

Like many desiccant units, this dehumidifier's water tank was on the smaller side, but I didn't find this a problem. I could still leave the dehumidifier for several days before needing to empty it – and the longer I used it in the space, the less attention it needed.

When the water tank is full, a full cup symbol appeared on the control panel and the dehumidifier switched itself off automatically.

Switching to continuous drainage mode

Unlike other machines, the continuous drainage on this machine is very easily accessible at the back, with its own removable rubber cover. This was perfect for use in a garage as there was no fiddling around trying to access it.

The spout, called the 'right angle adapter', meanwhile was hidden away in the water tank (ideal for not accidentally losing it) and slid easily into place. As with other Meaco dehumidifiers, it was annoying that no continuous drainage hose was included, although a piece of normal garden hose is apparently the right size for slotting onto the spout. You could also argue that sourcing one yourself means you can get the right length too.

It is worth noting that continuous drainage is gravity fed, so you do need a drain at the same level or below the machine for this to be workable, as well as a suitable outfall (drain, sink etc).

How did the dessicant dehumidifer perform?

This particular dehumidifier is absolutely perfect for use in a garage. Not only does this model perform efficiently in colder temperatures (as you would expect with a desiccant dehumidifier), but its adjustable power settings really tailor this machine for your space.

This gives users the choice to save on dehumidifier running costs by selecting a low watt setting, or cranking it up to max power for more needy spaces, and even whacking on the germ exterminator too.

But the DD8L Pro Desiccant dehumidifier, which is now available on Amazon, offers so much more; features that might not be useful inside a home, but are super useful in a garage or outbuilding. You can add wheels to move it around a large space, or a wall mount to increase useable floor space. Meanwhile, stick a hose on it and you've got yourself a secure, permanent drainage system.

Add to that the ability to control the dehumidifier remotely on your phone, or your Google Home Hub or Alexa, and you can give yourself a setup that rarely needs any input, saving you valuable time and effort.

While the Meaco DD8L pro desiccant dehumidifier is on the pricey end of the cost spectrum (desiccant dehumidifiers often are), I'd argue that for all the functionality it offers, this unit is well-worth the investment.

So, was the Meaco DD8L pro desiccant dehumidifier the perfect companion for the super car? Absolutely. Not only does this machine look cool next to the car, it is giving the garage (and the car) a steady 55%RH climate at all times. My partner is also more than happy to volunteer to look after it, which I take as a clear sign that the DD8L pro is doing an excellent job at giving his car the perfect storage climate while it is tucked up over winter.

If you are considering buying a dehumidifier for your home, don't make the dehumidifier mistake of skimping on your model. When it comes to budget vs premium dehumidifier, you'll end up getting a lot more value for money by investing in a unit that is powerful enough for the job.

If you're struggling with damp and condensation, most experts will advise you to invest in one of the best dehumidifiers, which tackle the problem at its root.

These appliances work wonders at removing excess moisture from the air, but they do have one downfall: they can get very expensive if you're looking for one that's any good. So, when I saw that the Kalorik 12L Dehumidifier is on sale for less than £100 on QVC this morning, I knew I couldn't gatekeep.

For reference, this model is usually £150, so you'd be getting a substantial £50 discount. I'm not sure how long this deal will stick around, so if I were in the market for a new dehumidifier, I'd be snapping it up quickly.

I appreciate that even on sale, £99 is still a lot of money to fork out, but I wouldn't recommend this if it wasn't going to be worth it. Using a dehumidifier can save you money in the long run – whether as a more energy-efficient way to dry your laundry or by reducing condensation damage to your structure and belongings.

Laura Crombie, QVC presenter and homes expert confirms, "This dehumidifier is an absolute steal at this price. It's super compact, quiet, and efficient. It wouldn't be right for huge spaces, but for reducing dampness and condensation in an average-sized room, it's perfect."

One of the coolest features is the three-colour light, which lets you monitor your home's conditions at a quick glance. It also has a digital display where you can check whether your humidity levels are normal, helping you maintain the perfect environment.

The Kalorik Dehumidifier has three settings: Auto (it starts working when humidity is higher than 3%), Dryer (works continuously with adjustable wind speed), or Sleep (the indicators gradually dim and wind speed is low) – giving you total control depending on how you want to use it.

As a handy safety feature, the device will automatically shut off when the water tank is full. There is also an auto-defrost mode to stop your dehumidifier from freezing up, as well as a child-lock function.

If you don't fancy splashing out on a dehumidifier for every room, you'll be happy to hear that this model features wheels, making it easy to glide from your living room to your kitchen as needed.

I don't know about you, but before I buy anything, I always check the reviews, and I saw that this dehumidifier has a five-star rating on QVC. Reviewers have been praising its portability, ease of use and how effectively it collects moisture from the air.

Since it's a compressor, this machine works optimally in temperatures from 5°C to 35°C, so if you're looking to put one in a chilly room like a basement or garage, this isn't going to be your best buy. Instead, you'll need a desiccant dehumidifier that works well in cold rooms.

Other dehumidifiers we recommend

If the Kalorik dehumidifier isn't quite what you're looking for, here are some other picks recommended by the Homebuilding team.

When you compare the Kalorik Dehumidifier to other similar models on the market, £99 is a bargain you’re unlikely to find cheaper elsewhere. With all the features you could possibly need for an average-sized room, it’s a deal I would jump on.

If you want to do more research before making your decision, I recommend learning the difference between a compressor and a desiccant dehumidifier, as well as how dehumidifiers work.

I've always opted for larger dehumidifier models when choosing units to review for this magazine, simply because I don't live in an apartment and have always assumed something more substantial is needed to make a difference to the humidity levels in my small cottage in East Anglia.

So when I was sent this tiny MeacoDry Arete One 6L Compact dehumidifier quite by chance when the larger dehumidifier I was meant to review sold out, I wasn't expecting much. But after putting this machine, which is only 40cm high, through its paces, I found myself questioning my previous assumptions about the best dehumidifiers.

Rarely do I come across a product that impresses me so much as this compact machine, which is pitched as a dehumidifier best suited to be used on a room-by-room basis. Here's why.

Unboxing the 'half-size' dehumidifier

This 6L dehumidifier is nearly half the size of its parent dehumidifier; the MeacoDry Arete One 25L dehumidifier, meaning when the box arrived, it was much smaller and lighter, making it less difficult to handle.

The packaging opened with no problems at the top, and the operating instructions were positioned as the first thing you saw. These were useful and easy to follow, reminding first-time dehumidifier users to ensure the dehumidifier had rested for at least six hours before switching on.

I did find it a bit of effort easing the dehumidifier out of the box as there were no handles on the side of the machine as I expected. But after I removed the plastic bag, I discovered the handle cleverly tucked into the top of the unit. Not helpful for the initial removal, but fantastic for everyday use and portability.

In terms of parts, there were two sets of instructions (full manual and a quick start guide) and the dehumidifier to unbox, plus a free HEPA filter affixed to the machine. Overall, I found the unboxing experience very easy and simple.

First impressions of the MeacoDry Arete One 6L

I've only used larger dehumidifiers before, so I didn't really know what to expect from this much smaller size dehumidifier unit. I've always found the larger units very good and the larger tank a huge benefit.

However, once this smaller "half-size" unit was unpacked, I was immediately impressed by its size and look rather than finding it at all inferior as I was expecting. Being smaller, it was less dominant in the room, meaning it was far less noticeable.

Once I'd worked out how to pull up the handle, it dawned on me how much more portable this dehumidifier was compared to the larger models. Typically, with larger models, I've ended up avoiding moving them too much as it's a bit of a faff lugging it up and down stairs, especially if there is any water in the tank. But this smaller unit lifts up to transport so easily, without being at all heavy, I can imagine moving it fairly regularly from room to room, depending on where it might be needed.

The design is also pretty slick. My model was the "charcoal" one, which is nice because all the areas where dirt and grime might accumulate (the rear air filter area and the top where you press the buttons) are darker meaning unsightly marks are disguised.

How I tested the dehumidifier

When testing the MeacoDry Arete One 6L Compact dehumidifier, I wanted to find out the answer to the following questions:

• Was it easy to operate?
• Was it effective in laundry mode?
• How quiet was it?
• How effective was it as an air purifier?
• How energy efficient and affordable is it?

I decided to test the small dehumidifier in three different settings in my home. First on a damp spot in the bathroom, second for drying laundry in the utility room, and lastly in a bedroom with single pane windows while sleeping.

Ease of operating the 6L dehumidifier

Turning the dehumidifier on for the first time was easy. All I needed to do was put it in the room I wanted to target, plug it in and press the "on" button.

I started off testing in the bathroom, where we had installed a glass shower panel during renovations rather than a shower enclosure. The glass panel hadn't been as effective as hoped, meaning spray from the shower regularly finds itself on the wooden skirting board, wall and limestone tiles outside the tray, causing a minor damp issue.

While an annoying problem, it was a good test for the half-size dehumidifier to see if it could make a difference by bringing down the humidity in the room.

The initial start-up

After positioning the dehumidifier in the bathroom and pushing down on the "on" button, the unit started dehumidifying the air without needing to press any of the other three buttons. The screen also lit up and helpfully gave me a room humidity reading of 65% on the screen, with a target humidity level of 55% already set automatically. Overall, I found the ease of initial start-up fantastic and unfaultable.

Setting the target humidity level

The quick start manual took me as far as turning the machine on, so it was time to take a deeper dive into the fuller instruction booklet to have a play around with adjusting the target humidity level.

I discovered this was achieved by pressing the water drop button either once for setting a "smart" target humidity of 55% or repeatedly pressing to scroll through target humidity options from 40% through to 70%. There was also a "CO" option available to set the dehumidifier to continuous.

A droplet with two arrows pointing upward shows on the screen when the dehumidifier is in dehumidifying mode. I found this moderately easy to operate, but definitely needed the instruction manual to understand how to do it.

Overall, I found the ease of operating the MeacoDry Arete One 6L Compact dehumidifier excellent. Despite needing the instruction manual to find my way around in the first instance, it was easy to remember how to make the adjustments after that.

In terms of how effective the dehumidifier was on the damp in the bathroom, it dropped the humidity down to a sensible level of 55% with ease when left in there overnight. I was impressed this tiny dehumidifier managed it, without the tank becoming full before the target level was reached.

Using the dehumidifier in laundry mode

After testing the dehumidifier in the bathroom, I moved it into the utility room to see if the dehumidifier would help speed up drying the handwashing on my drying rack. There is also a degree of humidity in this room anyway as I regularly have the washing machine, tumble dryer and handwashing sinks in action at the same time.

Setting laundry mode was fairly self explanatory for anyone that has used a dehumidifier before, it was the button with the T-shirt on it. Pressing this button once, set the target humidity level to 35% with a high fan speed, and the dehumidifier automatically switched itself off after six hours meaning it could be left on overnight without fear of sucking up too much humidity and wasting energy unnecessarily. A quick look at the instruction manual revealed that you can check how many hours are left on the timer by pressing the T-shirt button twice.

One thing I really loved was that I could easily lift and position the dehumidifier on the worktop. We don't have a large amount of floor space in our utility room, and it is a bit of a walk-through area, so being able to do this was incredibly useful.

Placing the dehumidifier on the worktop also gave me the chance to test its continuous drainage function and I quickly found that while a spout was included, tucked cleverly away in the water tank, it was a bit disappointing that there wasn't a hose pipe included with the unit. When I fixed the spout to the correct outlet, it wasn't long enough to drain straight into the sink. As a result, without a handy piece of hose, I had to abandon testing this and stick to using the water tank.

Overall, the dehumidifier surprised me at how effective it was in laundry mode, arguably just as effective as a larger model. I left the unit for the full six hours and found my clothing nicely dried afterwards – saving me the hassle of dealing with any nasty damp smells and needing to do any rewashing.

Noise levels when using the dehumidifier at night

After testing the dehumidifier in both the bathroom and laundry room, I was confident about sleeping in the same room as this small unit. The MeacoDry Arete One 6L Compact dehumidifier had already proven itself to be extremely quiet when running, as low as only 32 decibels (the quietest Arete One dehumidifier), even with the full fan speed turned on in laundry mode.

Even so, I dutifully switched the unit to "night mode" to avoid any chance of the dehumidifier being loud by pressing the half moon button, to trigger a slower, quieter fan speed and the screen lights to turn off. This would create optimal sleeping conditions so I could wake up the next morning with no condensation on the single pane windows in the room without it being disruptive in the night.

A quick check over of the guide showed that the humidity level could still be checked while the screen light was off by pressing the half moon button once. There was also a child lock mode (indicated with a padlock) set by holding this half moon button down for two seconds.

The next morning, I woke to condensation-free windows after an undisturbed sleep so it got a resounding thumbs up. There was certainly no need for a more powerful machine in my double-sized bedroom.

Using the dehumidifier as an air purifier

I didn't actually realise this dehumidifier was also an air purifier at first, but it turns out, air purifying happens automatically while dehumidifying if a HEPA filter is fitted.

A read of the instructions highlighted that this clever little unit can also be used exclusively as an air purifier on its own. Is that actually useful? Well, yes because in times when there might be low humidity, like the summer, you might want air purifying in your room to ease allergies without having to run the dehumidifier simultaneously.

Air purifying mode was selected using the same water drop button but holding it down for two seconds to select "AP" mode. This was easy once I'd read up on how to do it, but in all honesty I probably wouldn't have worked it out without doing that.

You can confirm the dehumidifier is in air purifier mode by checking the icon with the arrow pointing right with a line cutting through it, is visible on the screen. Overall, I found this function most useful at night to avoid waking up stuffy. I always find air purifiers difficult to test conclusively, but can confirm I had a comfortable night's sleep with it switched on.

Affordability of the MeacoDry Arete One 6L

The energy efficiency of this 6L unit is something to really shout about at only 101 watts, compared to 151 watts for the 12L model and 267 watts for the 25L model. This gave it a 3p per hour cost based on 26.35p/kWh energy pricing. There is also an argument that by targeting a home room-by-room, this can also keep down the running time of the dehumidifier, thus lowering dehumidifier running costs.

Affordability of the unit however was where I was initially a little disappointed. With an almost half-size model, I naturally expected a half-size price tag. Yet this 6L model was priced at £129.99 on the Meaco website, while the larger 12L version was £179.99 on the Meaco website in comparison; only a £50 difference. However, the larger 25L version was a larger jump up in price at £299.99 on the Meaco website.

But on further reflection, you could argue that a smaller dehumidifier should actually command a higher price tag if it performs the same job, with the same performance, while taking up less space. Certainly this can be true when it comes to other technology such as computers.

So is my initial disappointment over the price justified? Absolutely not when you take all this into account. Its smaller stature ended up being a huge benefit rather than a hindrance. I was able to move the unit far more easily from one room to the next, potentially saving on needing to buy a second unit, and it packed away easily into a kitchen cupboard when not in use. The MeacoDry Arete One 6L Compact dehumidifier was also much quieter and economical than a larger dehumidifier so all-in-all it is being sold at a hugely competitive price point.

Final thoughts

It goes without saying that I definitely recommend the MeacoDry Arete One 6L Compact dehumidifier. It is not only excellently priced, it is highly portable (more of a plus than I realised before testing), yet also highly effective despite its tiny size.

And for that reason, I would snap up one of these small dehumidifiers, before it too is sold out like the other Meaco dehumidifier I was meant to review.

If you are looking to alleviate damp or stop mould in a garage, colder outbuilding or campervan or caravan with a power source, you would be much better opting for a desiccant dehumidifier specially designed to handle lower temperatures and this kind of environment.

You can read up on my review of the EcoAir DD2 desiccant dehumidifier, which I highly recommend, or if you prefer sticking to the Meaco brand, you can hold on for my review of the Meaco DD8L Pro Desiccant Dehumidifier in January when it is back in stock on the Meaco website.

Living in a damp Victorian home, with a lounge right next to a downstairs bathroom, I had almost given up on ever having a dry, comfortable space.

I had tried cheap moisture absorbers that barely made a dent in the problem, but then I got the Duux Bora dehumidifier.

It quickly showed why it’s the best dehumidifier for managing heavy moisture, keeping the air fresh and the room comfortable in ways I hadn’t experienced before.

Intelligent moisture control with integrated hygrostat

The standout feature of the Duux Bora dehumidifier is its combination of powerful water absorption, integrated hygrostat, and efficient R290 refrigerant technology, which removes moisture effectively while being environmentally friendly.

My lounge regularly reached 70–80% humidity, well above the government's Housing Health and Safety Rating System's recommended 40–60%, and the Duux Bora dehumidifier reduced my humidity levels to below 60%.

Its 20L extraction capacity (although it also comes in 12L and 30L options) also ensures it can remove large amounts of moisture efficiently, while the hygrostat adjusts the operation so the room stays perfectly balanced without the need for me to constantly monitor it.

Laundry-drying mode & practical design

The laundry-drying mode is fantastic for drying robes and towels straight from the shower, preventing them from staying damp for hours.

The Duux Bora dehumidifier also comes with a continuous drain hose, allowing for uninterrupted operation during heavy moisture periods.

On top of that, the smooth rollers make it easy to move the unit from room to room whenever needed, adding convenience and flexibility to its high-capacity performance.

Low-maintenance filtration

Because the lounge sits next to a bathroom, odours and damp smells used to linger. The carbon filter in the Duux Bora dehumidifier freshens the air as it removes moisture, leaving the room cleaner and healthier.

Maintenance is simple: cleaning the Duux Bora dehumidifier is easy thanks to its smooth design, plus I only need to wash the filter every two weeks, and it only needs replacing once a year.

I tend to empty the 4L tank every morning if it’s been left running overnight, and then once again during the day. But the Duux Bora dehumidifier also includes a drainage hose, so I can run it into a sink or larger container for continuous draining, which saves me from having to empty the tank as often.

Smart app control & Indoor Climate View

The new Duux app allows me to operate the Duux Bora dehumidifier from anywhere in the world, set up to seven schedules, and track indoor air quality over time.

The Indoor Climate View shows real-time humidity levels in each room where the unit is used, based on readings collected whenever I move it.

The Duux Bora dehumidifier also integrates with Google Assistant and Amazon Alexa, making it easy to adjust settings remotely or hands-free.

Is the Duux Bora dehumidifier worth it?

The Duux Bora dehumidifier has been a game-changer for my damp Victorian lounge, but it’s worth noting other dehumidifiers can offer different advantages.

The Meaco 20L Low Energy dehumidifier includes a HEPA filter that captures dust and mould spores, providing stronger air-purifying performance than the Duux Bora dehumidifier.

The ProBreeze 20L Premium dehumidifier shares features with the Duux Bora dehumidifier, including a 20 L tank, laundry mode, and continuous drain hose, but it is noted for slightly lower running costs when compared at the highest settings.

While these models have their strengths, the Duux Bora dehumidifier stands out for its smart hygrostat, app control, sleek design, portability, and overall convenience.

If you see any signs you might need a dehumidifier then don't hesitate like I did and get the best all-round solution for comfort, moisture control, and healthier air whilst it's still on offer.

We know dehumidifiers are great for tackling damp and condensation, but do they help with allergies? If you struggle with sensitivities at home, you might be wondering whether these machines can make a difference – and if they’re worth the investment.

Since most indoor allergens thrive in humid environments, the best dehumidifiers can significantly reduce symptoms by limiting common triggers such as mould and dust mites. They also help prevent dampness, which can irritate the airways.

Below, experts explain everything you need to know about using a dehumidifier for allergies – from whether sleeping with one can be beneficial to which sensitivities they can help with, as well as why high humidity levels can be so triggering.

Do dehumidifiers help with allergies?

Yes, dehumidifiers can help with allergies, according to Dr. Stephanie Kayode, Allergy Physician at Allergy Care London.

If your home has excessively damp air, you're likely to have high amounts of mould spores, bacteria, and dust mites which can be inhaled – triggering immune responses, infections, and allergic reactions.

Dr. Kayode says, "This is why high-humidity environments are linked to asthma flares, chronic cough, bronchitis, allergies, and increased respiratory infections."

To find out whether you have normal humidity levels, you can buy a hygrometer (like this one from Amazon) to monitor your home. Dr. Kayode recommends keeping the environment in the range of 40 to 60%. If you’ve noticed your levels are too high, it’s well worth investing in a dehumidifier to help bring them down.

She says, "In this range, damp, mould and dust mites are controlled, mucosal barrier defences are not impacted, and the lungs and skin function better. Since we spend most of our time indoors, breathing in higher concentrations of airborne allergens increases the likelihood of developing allergy symptoms, such as asthma, wheezing, chest tightness, coughing, runny nose, nasal congestion, sneezing, watery eyes and itchy eyes."

Which allergies can a dehumidifier help with?

Dehumidifiers can be especially beneficial for people with mould and dust mite allergies.

Dr. Hussain Ahmad, Consultant Practitioner at Click2Pharmacy, explains: "Dust mites need humidity above 40 to 50% to survive, so reducing moisture in your home makes it harder for them to thrive. Mould spores also love damp conditions, which is pretty common in UK homes unfortunately."

What is better for allergies: humidifier or dehumidifier?

By contrast, humidifiers add moisture to the air, which can help ease irritation and inflammation caused by allergies. So, are humidifiers or dehumidifiers better for relieving allergy symptoms?

Since damp air is a more common problem than dry air in the UK, Dr. Hussain Ahmad says that dehumidifiers are generally the better option. In fact, a humidifier can even worsen reactions to dust mites and mould.

He explains, "The only time a humidifier might help is if someone's got very dry nasal passages from over-heated homes, but that's less common. Get a cheap hygrometer and measure your humidity."

Does sleeping with a dehumidifier help allergies?

If your bedroom is damp or you have dust mite allergies, sleeping with a dehumidifier in the room can be helpful, says Dr. Hussain Ahmad. He explains that since we spend so much time in our bedrooms and bedding harbours dust mites, these spaces can be major problem areas.

Other ways to reduce allergies at home

Looking for other ways to reduce your allergy symptoms at home? Here's what Dr. Stephanie Kayode recommends:

1. Use an air purifier: Air purifiers with HEPA filters can reduce allergen concentrations by around 65% to 90%.

2. Consider airflow: Your air purifier will be more effective at reducing allergens if there are higher airflow rates in your home.

3. Cleaning: By vacuuming regularly, you will reduce exposure to dust and animal allergens that can trigger your symptoms. Don't forget to damp-wipe your surfaces and remove unnecessary soft toys and furnishings, which build up dust over time.

Dr. Hussain Ahmad concludes, "Make sure you clean your dehumidifier properly and empty it regularly, or you'll end up with mould growing in the unit itself, which defeats the purpose."

Have you noticed your dehumidifier freezing up? If so, this isn’t something you should ignore, as it could indicate a problem with your device or that it's placed in an unsuitable environment that needs to be addressed.

A frozen unit has to work much harder to filter your air, which can cause it to overheat or burn out – potentially leading to a broken dehumidifier. Since it won’t be able to remove moisture from the air effectively, you’ll also waste energy and still have excess humidity in your room, so it’s best to get the problem sorted as soon as possible.

To learn why your dehumidifier is freezing up, keep reading. Our experts explain two common causes of this issue, what you can do to prevent it from icing up in the first place, and how to fix it if it happens.

Why is my dehumidifier freezing up?

There are two common reasons why your dehumidifier might be freezing up:

1. You've chosen the wrong dehumidifier
If you’re using a compressor dehumidifier in temperatures below 15°C, it’s highly likely to freeze up. Since this model uses a refrigerant, it will enter defrost mode if the coils get too cold – just like a fridge.

It will also spend more time defrosting than dehumidifying the air, reducing efficiency and wasting energy. Prolonged freezing could also damage your unit, which is why it’s important to choose a dehumidifier designed for cold rooms.

Katie Lilywhite, Category Buyer at AO says, “Most compressor dehumidifiers will struggle when the air temperature dips below 15°C as the moisture can freeze on the coils instead of dripping into its water tank."

2. There's poor airflow
Dehumidifiers can also freeze up due to poor airflow, such as a vent that’s blocked with dust or debris, or if the unit is placed too close to a wall or object. That's one of the reasons it's so important to regularly clean your dehumidifier.

When airflow is restricted, the coils don’t get enough warm air passing over them, making them colder than they should be and leading to a build-up of cold spots and ice. This ice can further restrict airflow, worsening the situation and reducing the unit’s efficiency.

How do I stop my dehumidifier from icing up?

To stop your dehumidifier from icing up in the first place, Katie Lilywhite says that choosing the right model is key. If you plan to use it in a cold room, such as an unheated garage or basement, then a desiccant dehumidifier is your best bet, as compressor models don’t work well in low temperatures.

To ensure your unit gets enough air circulation, move it away from walls and furniture to give it plenty of space to breathe.

Regularly cleaning your dehumidifier is another way to prevent restricted airflow, as Katie previously explained. Not only will this stop ice from forming, but proper maintenance will also extend the lifespan of your unit, improve its efficiency, and prevent mould and bacteria from developing inside.

Laura Bradbury, Head of eCommerce at Vonhaus, adds, "Many models have an automatic defrost setting that pauses operation until the ice melts, so the unit can get back to work safely without damage.”

How to fix a frozen dehumidifier

If you've noticed a little bit of frost on your dehumidifier, Laura Bradbury reassures that it will usually clear within 15 to 30 minutes, and most modern devices can manage this automatically. “Once the ice has melted, they’ll switch themselves back on and carry on as normal.”

However, if this isn’t the case, Viktor Velikov, Director at Elserve, recommends the following:

1. Turn your dehumidifier off
2. Let it fully defrost before switching it back on
3. Make sure the filter is clean as blocked air flow can cause icing
4. Ensure the room temperature stays above 15°C.

By choosing the right model for your home's temperature and following proper dehumidifier maintenance, you can prevent your unit from freezing up and causing serious damage.

However, if you've noticed other problems with your device – like unusual noises – and think it might be nearing the end of its life, it's worth learning how long dehumidifiers typically last to see if you're due for an upgrade.

As the weather gets colder and temperatures start to drop in your home, you might wonder which dehumidifier is best for cold rooms. These units are incredibly handy for removing dampness and condensation, but not all are designed for the same conditions – and you’ll face problems if you choose unwisely.

When selecting the best dehumidifier for your needs, it’s important to consider where you’ll be placing it to ensure it operates properly. While some models thrive in chilly conditions, others may freeze up, stop collecting water, or shut down completely to prevent damage.

Below, we’ve asked the experts which dehumidifier is best for cold rooms, why certain models don’t perform as well in these environments, and their top tips for using your machine during the winter season.

What is the best dehumidifier for a cold room?

Desiccant dehumidifiers are best for cold rooms, according to Chris Michael, Founder of Meaco. So, for rooms that rarely exceed 10°C, like a cold conservatory, utility room, garage, boat, or caravan, this is the model for you.

If you take a look at how dehumidifiers work, desiccant models use a moisture-absorbing material to capture water vapor. Since they don't rely on a cooling process (as compressor models do), they won't freeze up or cause related problems if they're in the cold.

Desiccant models also have the added bonus of extra warmth. "The air generated by a desiccant dehumidifier is 10-12°C warmer than room temperature, so this extra heat can be a welcome way to keep a room a little cosier," explains Chris. "Naturally creating this extra warmth has a cost, so it’s recommended weighing up whether this benefit offers you the best value for money for your needs."

Laura Bradbury, Head of eCommerce at Vonhaus, recommends finding a dehumidifier with a dedicated low-temperature or frost-protection setting, as these are made to work well in colder climates.

Why don't compressor dehumidifiers work in the cold?

You might think that desiccant and compressor dehumidifiers work in the same way, but that's not the case.

"Compressor units run on a refrigerant," explains Chris. "So, just like a fridge, if they get too cold, they go into defrost. While this is not a bad thing, and the units will do this cycle from time to time, you don’t want to spend your money on a machine that will defrost more than it will dehumidify."

To get the most out of your compressor dehumidifier, place it in a room where the temperature is 15°C or higher.

Do you need to use a dehumidifier differently during the winter?

Should you use your dehumidifier differently during the winter? The answer is yes, according to Laura Bradbury.

She explains, "In winter, rooms are often cooler and have less airflow, so it helps to move your dehumidifier to the areas where moisture builds up, such as near windows or laundry spaces. Closing doors and windows helps it work faster, and running it for longer periods can make up for the colder air."

Now that you know which dehumidifier is best for cold rooms, you can prevent your unit from freezing up, wasting electricity – or worse, malfunctioning and shutting down completely, which is one of the most common dehumidifier mistakes.

If you're wondering whether the colder seasons affect how much you'll pay to run your machine, read our explainer on dehumidifier running costs, which breaks it down.

Are dehumidifiers loud? If you plan to use one in your bedroom while you sleep or spend a lot of time at home, you’ll probably be asking yourself this question before buying one.

The best dehumidifiers are a lifesaver when it comes to removing dampness and condensation, but since they often run for long periods throughout the day, you might be wondering whether the noise will be bothersome.

To find out if dehumidifiers are loud and what you can do to reduce the sound, we asked the experts for their advice – plus, whether a noisy device indicates an issue and how to make them run even quieter so they don't become a problem.

Are dehumidifiers loud?

“While no dehumidifier, or indeed appliance, is ever truly silent, some models can come impressively close," explains Katie Lilywhite, Category Buyer at AO.

You can expect a dehumidifier to run between 35 decibels (similar to the sound of a whisper) and 50 decibels (comparable to the volume of a normal conversation). So, when choosing your device, try to opt for one with the lowest number possible.

If you plan to put your dehumidifier in your bedroom, Katie recommends choosing a model below 40 decibels to avoid disrupting your sleep – some even feature a special 'night' or 'quiet' setting that reduces fan speed. For example, the MeacoDry ABC 12L, which our Assistant Editor Sarah tested, features a sleep mode.

It's worth bearing in mind that desiccant dehumidifiers are usually the quietest, as they don’t have a compressor that produces a lot of noise.

How to make a dehumidifier quieter

While you won’t be able to make your dehumidifier run more quietly than it was designed to, there are a few ways to help it operate more efficiently – and therefore reduce noise.

Here's what Katie Lilywhite recommends:

1. Set your model to the quietest setting
2. Place it on a level surface to prevent extra vibrations
3. Position it away from walls and furniture to give it enough room to breathe
4. Clean your dehumidifier regularly to prevent dust build-up in the fan
5. Clean or replace the filter regularly
6. Vacuum the air intake vent

Why is my dehumidifier making a loud sound?

Every dehumidifier is bound to make some noise, but if you’ve noticed a change in volume, it could signal a problem.

Viktor Velikov, Director at Elserve, says, "Dehumidifiers make some noise by design. The compressor and fan both generate sound as they pull moisture from the air. But if yours has become noticeably louder or makes rattling, grinding, or humming noises, something’s off."

If you suspect your dehumidifier is broken, Viktor recommends unplugging it, cleaning the air filter, tightening any loose screws, and removing dust or debris around the fan. It might be worth finding out how long dehumidifiers typically last to see if yours is past the expiry date.

He adds, "However, if the noise still continues after this, the problem may be with the fan motor or bearings, which usually calls for professional repair or replacement."

While choosing a quiet model is your best bet, there are a few additional steps you can take to help reduce noise, like keeping up with regular dehumidifier maintenance.

To keep yours running smoothly and prevent noise-related issues, make sure to avoid these common dehumidifier mistakes too.

How long do dehumidifiers last? If you own one of these moisture-busting machines, you've probably asked this question. Dehumidifiers can be expensive, so it's worth knowing when yours might reach the end and what you can do to make it run longer.

Just like any other appliance in your home, even the best dehumidifiers have an inevitable lifespan. However, there are steps you can take to help them run efficiently for longer – whether it’s using auto mode initially to prevent motor strain or thoroughly drying the unit after cleaning to prevent mould build-up.

Below, we explain how long dehumidifiers typically last (spoiler: there’s a difference between compressor and desiccant models) – plus expert advice on how to prevent them from burning out prematurely.

How long do dehumidifiers last?

Provided you treat them with proper care and follow standard dehumidifier maintenance advice, dehumidifiers can last between five and 10 years, according to Katie Lilywhite, a dehumidifier expert at AO.

However, it's worth bearing in mind that desiccant dehumidifiers can wear out faster than compressor models, as their absorbent material degrades over time. The lifespan also depends on the quality of your device, how you store it and how often you use it.

How to extend your dehumidifier's lifespan

1. Go easy after summer
If your dehumidifier has been sitting in a cupboard all summer, you'll want to go easy the first time you use it again. Rather than blasting it on maximum power, Katie Lilywhite recommends running it on gentle auto mode first. This will prevent straining the motor, causing wear and tear that could shorten its lifespan.

She adds, “You’ll also need to give it a little bit of TLC. Clean the dehumidifier's filter, as dust can build up in storage, and similarly, wipe down the exterior to prevent any further dust from hindering your appliance. Now’s the perfect time to check your dehumidifier’s water tank – give it a once-over and make sure it’s dry and mould-free.”

2. Keep the windows closed
If you keep the windows open while using your dehumidifier, not only are you increasing the dehumidifier's running costs, but you’re also forcing your unit to work much harder – which can eventually shorten its lifespan.

Katie explains that your dehumidifier will be constantly battling against fresh, damp air being blown in, which can have “detrimental effects” on the compressor, fan and motor (as well as your bank account!)

3. Store your dehumidifier correctly
If you’re not planning to use your dehumidifier for a while, it’s important to store it properly to prevent any damage. Laura Bradbury, Head of eCommerce at VonHaus, recommends emptying and drying the water tank, cleaning or replacing the filter, and wiping down the exterior before packing it away.

She adds, "Store it somewhere cool, dry and out of direct sunlight – a cupboard or utility room is ideal. Avoid garages or sheds, as damp conditions can damage the internal parts over time."

How do I know when to replace my dehumidifier?

Wondering whether it’s time to repair or replace your dehumidifier? Here are some signs it might be broken:

1. It fails to lower humidity
   If your unit runs continuously but fails to reduce humidity, this usually signals a problem with the compressor or refrigerant, explains Viktor Velikov, director at Elserve. "The appliance may seem to operate normally, yet moisture is not being removed because refrigerant pressure has dropped or the compressor valves are worn," he says. "These faults cause the system to overwork while performance steadily falls, showing that failure is imminent."
2. Reduced airflow or uneven cooling across the coils
   Reduced airflow or uneven cooling is another indication that your dehumidifier may be on its way out. If that's the case, Viktor recommends stopping operation, cleaning or replacing the filters, and having a professional inspect it. "Prompt maintenance restores efficiency and prevents the compressor from burning out – avoiding a complete breakdown and higher repair costs," he says.
3. It makes unusual noises
   If your dehumidifier is making peculiar sounds – like rattling, humming or buzzing – it could be a sign that it’s about to expire or that there’s an issue that needs to be resolved.
4. It has a musty smell
   A musty smell could be a sign of mould or mildew building up inside, which is why regular cleaning is essential.

Will running a dehumidifier all day damage it?

As long as you keep your dehumidifier well-maintained, it won’t be damaged by running it for long periods, assures Laura Bradbury, Head of eCommerce at VonHaus.

However, she advises that eight to twelve hours per day is usually enough for most homes (depending on humidity levels), and that short bursts often work better than running it all day long.

As long as you take good care of your unit, there's no reason a high-quality model shouldn't last between five and ten years. By avoiding common dehumidifier mistakes, you can help it last even longer without needing early repairs or replacement.

There are plenty of benefits to having a dehumidifier in your home – from preventing mould and mildew to improving overall air quality. With all these advantages, you might think it’s a good idea to collect as many as possible to maximise the effects – but can you actually have too many dehumidifiers?

According to experts, the answer is yes. While the benefits of the best dehumidifiers are undeniable, it is possible to have too much of a good thing. If you use more than you need, your indoor air could become overly dry, leading to damage in your home and irritation to your body.

To get to the bottom of how many dehumidifiers is too many and how it could impact your home and health, we spoke with experts.

Can you have too many dehumidifiers?

Yes, you can have too many dehumidifiers – most homes only need one per problem area.

"You might use one in a damp basement, another in a condensation-prone bedroom, or a utility room where you use a dehumidifier to dry clothes," explains Laura Bradbury, Head of eCommerce at Vonhaus."Even in a large home, two or three units is usually enough. Capacity matters more than quantity; a higher-capacity unit can often cover several rooms.”

How can too many dehumidifiers affect your home?

It's widely accepted that excess humidity can wreak havoc on your home – warping wooden furniture and floors and creating the perfect environment for mould and mildew to thrive. However, having too many dehumidifiers can be bad news too.

"When indoor air becomes overly dry, it can start to affect natural materials like wood and paper," explains Michael Zohouri, Founder of Pyramid Eco. "You might see wooden floors and furnishings start to shrink or crack, and any books and paperwork could become brittle. Your houseplants will also suffer as they need moisture in the air."

Is this the same for both compressor and desiccant dehumidifiers? According to Michael, the answer is no. While desiccant models continue extracting moisture even when the air is already dry, compressors are generally self-limiting and become less efficient as the air dries out or cools down, which helps prevent overuse.

While it's not common for UK homes to become too dry (especially during the colder months), Michael confirms that it is possible, and running more units than necessary can cause problems. This is particularly true for smaller, well-sealed homes.

As a rule of thumb, Michael says to avoid letting humidity drop below 40%, which the ProBreeze 20L Premium Dehumidifier allows you to monitor via its display.

How can too many dehumidifiers affect your health?

We now know that having too many dehumidifiers can potentially cause issues for our home, but what about our health?

"Using multiple dehumidifiers in the same home can dry the air too much. Our airways need a bit of moisture in the air so that they can trap dust, allergens, and germs," explains Dr. Praveen Bhatia, NHS Respiratory Consultant.

"Very dry air irritates your airways, nose, eyes and skin, and will worsen breathing rather than helping. This is especially true if you suffer from asthma – dry air can trigger flare-ups because the airways become more sensitive."

What matters most is keeping the humidity balanced, which you can do by monitoring the environment with a humidity monitor (also known as a hygrometer) and aiming for a sweet spot of 40 to 50%. Some dehumidifiers may display this information automatically.

If your whole home is damp, Dr. Bhatia notes that it might be useful to have one unit per affected area, but usually one or two units are sufficient to stay in the normal humidity range.

FAQs

Can having too many dehumidifiers damage the units?

While it won't do your dehumidifiers any damage by having too many, it certainly isn't efficient and can make your air uncomfortably dry, explains Laura Bradbury, Head of Ecommerce at Vonhaus.

She says: "It’s better to choose the right capacity for the space. That way you protect your home, your comfort, and your energy bills.”

Although there's no one-size-fits-all solution, choosing the right size dehumidifer for its intended use and space is the best place to start when making your product selection.

How much exposure should I have to a dehumidifier?

If humidity levels drop below 40%, the air can feel harsh and uncomfortable. Dr. Praveen Bhatia, NHS Respiratory Consultant, recommends running your unit for a few hours a day or setting it to stop automatically once the desired humidity level has been reached.

As we’ve learned, it’s definitely possible to have too many dehumidifiers, but that doesn’t mean we need to get rid of them altogether. They’re incredibly useful for preventing mould and mildew and for alleviating allergy and asthma symptoms – having them in excess is just one of the common dehumidifier mistakes.

As Laura Bradbury says, “The trick is balance – remove excess moisture without stripping the air completely.”

As a final point, remember that cleaning a dehumidifier is also essential to ensure it runs as efficiently as possible.

Dehumidifiers are brilliant for keeping damp and mould at bay, but while they’re great at managing humidity levels, they could be quietly working against your houseplants.

Most indoor greenery prefers a little moisture in the air, and when humidity levels drop too low, plants can start to show the strain. Crispy leaf tips, yellowing foliage and slow growth are all signs that your leafy companions may be feeling the effects of dry air.

Thankfully, you don’t need to choose between fresh, healthy air and thriving greenery. With advice from horticultural experts, we’ll explore how dehumidifiers affect houseplants and the simple steps you can take to keep your home humidity levels in check while ensuring your collection continues to flourish.

What do dehumidifiers do and why does this matter for plants?

Dehumidifiers work by pulling moisture out of the air to reduce humidity levels in your home. That’s excellent news if you’re trying to prevent damp patches on walls, reduce condensation on windows or cut down the risk of mould spores spreading.

But the problem is that most houseplants rely on a certain level of air moisture to stay healthy. While humans are comfortable with indoor humidity between 30% and 50%, many plants – particularly those that originate from tropical or woodland environments – prefer things a little higher.

When the air becomes too dry, they can lose water from their leaves faster than their roots can replace it, leading to stress and visible damage.

How could dehumidifiers harm your houseplants?

According to Richard Barker, horticultural expert and commercial director of LBS Horticulture, most houseplants don’t respond well when humidity levels get too low:

“Most houseplants do not like the air to be too dry, and some can suffer more than others if humidity levels are low," he explains. "However, this will depend on the settings of the dehumidifier and how much it is decreasing the level of humidity in the room, as a setting designed to dry laundry faster will lower humidity much more than the standard settings.”

According to Angelika Zaber, horticultural expert at Online Turf, the signs that your plants are suffering from low humidity can be quite easy to spot:

• Brown and crispy leaf tips and edges.
• Wilting or drooping foliage.
• Leaves that feel dry to the touch.
• Yellowing patches across the plant.
• Stunted or slow growth.

All of these issues stem from the same problem – the plant is losing water through transpiration faster than it can take it up, leaving it dehydrated and stressed.

Richard Barker notes that, “Plants that are most sensitive to dehumidifiers are those that would normally thrive in high humidity environments or naturally grow in tropical areas, including peace lilies, ferns, calatheas (prayer plants), orchids and English ivy.”

By contrast, hardier plants like succulents, cacti, or snake plants are more tolerant of drier conditions and less likely to show distress.

How to balance healthy air for people and plants

The key to keeping both your home and your houseplants happy is balance. Appliances like dehumidifiers and humidifiers can make a big difference to indoor air quality, but it’s worth understanding how they interact with your greenery. Here are some practical ways to keep both people and plants comfortable:

Consider your dehumidifier settings

Laundry-drying modes on dehumidifiers can strip moisture from the air quickly, so it’s better to use gentler, everyday settings if plants are nearby. Some appliances, such as The Meaco Arete® Two Dehumidifier from John Lewis, include a built-in humidistat that allows you to set a preferred relative humidity to prevent the air from becoming overly dry.

According to Chris Michael, MD of Meaco, the commonly repeated guideline of 40–60% relative humidity indoors may not be the best fit for the UK climate. With a background in humidity control for museums – where even small fluctuations can damage precious artefacts – he suggests aiming for 50–60% RH instead.

“It’s a waste of electricity to task a dehumidifier to work towards below 50% RH unless there’s a specific reason to do so,” Chris explains. Around 55% RH for the ideal balance, as it's dry enough to keep damp and mould at bay, but not so dry that your favourite plants suffer. This setting will also reduce dehumidifier running costs.

Likewise, if you're using a humidifier in your home, remember to keep the settings moderate. Too much moisture in the air can encourage mould growth and even cause harm to houseplants that prefer a drier climate. A hygrometer (a simple humidity monitor) can be a useful gadget for checking conditions in different rooms before you decide whether to run a dehumidifier or a humidifier.

Create a microclimate for your houseplants

According to Richard Barker, grouping plants together, misting leaves, or placing pots on a pebble tray can all help raise local humidity. You can even use a glass dome or cloche to trap moisture around delicate species.

It’s also worth thinking about houseplant placement. Kitchens and bathrooms tend to have higher humidity levels and can be ideal for tropical plants, provided there’s enough natural light. However, you should always avoid putting them near radiators, draughts or directly on underfloor heating.

Top Tip: If houseplants are sharing a room with a dehumidifier, they may need a little extra water. Just avoid leaving roots sitting in soggy soil.

Dehumidifiers can happily co-exist with houseplants as long as you keep an eye on settings and room humidity. If you’re unsure how to use a dehumidifier, start by checking for the signs you need a dehumidifier at home – condensation, lingering damp smells or patches of mould. Once you know the balance, you can keep both your plants and your indoor air in top condition.

Wall-mounted dehumidifiers might not be the first thing that comes to mind when you think about managing humidity, but they offer a unique approach to keeping your home comfortable.

Designed to free up floor space while tackling dampness and moisture, they’re an intriguing option for spaces like utility rooms, studios, and even holiday homes.

This article will break down everything you need to know about wall-mounted dehumidifiers, their advantages, disadvantages, costs and how they compare to the best dehumidifiers on the market.

How do wall-mounted dehumidifiers work?

A wall-mounted dehumidifier operates in much the same way as a standard dehumidifier. It draws in moist air, cools it to condense the water vapour into liquid, and then releases dry air back into the room.

What sets wall-mounted models apart is their ability to be securely affixed to a wall. This is often paired with a gravity-fed drainage system, which allows the collected water to flow out through a hose, eliminating the need to manually empty the water tank and requiring less maintenance.

According to Chris Michael, managing director of Meaco: "A wall-mounted domestic dehumidifier is basically a normal dehumidifier with the ability to be wall-mounted. It’s particularly useful in spaces like rented accommodations, garages, workshops, and laundry rooms where floor space is limited or continuous drainage is needed."

Pros and cons of wall-mounted dehumidifiers

Wall-mounted dehumidifiers are ideal for saving floor space and enabling continuous drainage, making them perfect for small homes, holiday properties, or utility rooms.

However, these models have limitations. They are less common, more expensive, and require careful installation.

James Longley, Managing Director at Utility Bidder, explains: "The number of units with wall mounting brackets is limited, and uneven mounting can lead to water leaks or increased vibration." While fixed in one spot, they excel in areas where portability isn’t a priority.

How much should a wall-mounted dehumidifier cost?

Wall-mounted dehumidifiers generally cost more than their freestanding counterparts due to their specialised design.

Prices can range from £150 to £400 or more, depending on the brand, capacity, and additional features.

Some models, like those from Meaco, include vibration dampers in their mounting brackets to prevent noise and reverb through walls, which can add to the cost but significantly improve the user experience.

Shop for freestanding dehumidifiers

How do they compare to regular dehumidifiers?

Freestanding dehumidifiers offer portability, allowing you to move them from room to room. Wall-mounted units, on the other hand, are fixed, making them more suited for specific-use cases.

Wall-mounted dehumidifiers are a clear winner in tight spaces. As Chris Michael explains: "For the majority of households, a freestanding dehumidifier makes more sense. But in areas like utility rooms, garages, or rented accommodations, wall-mounted units excel."

With a continuous drainage setup, wall-mounted models require less regular attention compared to freestanding models with tanks that need frequent emptying.

While the upfront cost of wall-mounted models can be higher, the convenience of continuous drainage may save time and effort in the long run.

Should you buy a wall-mounted dehumidifier?

The decision to invest in a wall-mounted dehumidifier depends on your specific needs:

• Space constraints: If you’re dealing with limited floor space in areas like laundry rooms, small homes, or caravans, a wall-mounted model could be a perfect solution.
• Continuous use: If you need a dehumidifier to run continuously without manual intervention, such as in rented properties or holiday homes, wall-mounted units with a drainage system are highly practical.
• Budget: If cost is a concern, weigh the benefits of the wall-mounted design against more affordable, freestanding options.

As Chris Michael emphasises: "Mounting your dehumidifier to the wall is ideal for those who don’t want to – or can’t – regularly empty a water tank."

Wall-mounted dehumidifiers are a niche, but highly effective solution for specific scenarios. While they might not replace the flexibility of traditional freestanding models for most households, they are an excellent choice for spaces where saving floor space and hassle-free operation are priorities.

However, if you're wondering if a wall mounted dehumidifier could be a solution for your bathroom, then think again. Follow this advice regarding using dehumidifiers in bathrooms and instead make sure you've covered all of your other bathroom ventilation options instead.

A broken dehumidifier can be a real headache, especially when you’re counting on it to keep your home dry and comfortable. If your dehumidifier isn’t collecting water, it’s easy to fear the worst. But don’t worry – most issues are simpler to resolve than you might think. With a little troubleshooting, you can get your unit back up and running in no time.

Dehumidifiers are brilliant for tackling excess moisture, preventing mould, and freshening up your home. However, like any appliance, they need the right conditions and regular care to perform their best. Identifying why your dehumidifier has stopped collecting water is the first step towards a solution.

Below, we’ve outlined the six most common reasons your dehumidifier might not be working properly – and how to fix them. From cleaning filters to managing cold conditions, we’ll help you get things back on track.

1. The water tank needs emptying

Sometimes, the simplest solution is the answer. If your dehumidifier’s water tank is full, the unit will automatically shut off to prevent overflow. Chris Michael, manager director of Meaco, explains, “Dehumidifiers have a float which measures when the tank has reached its limit. At this point, the unit will stop collecting water and turn off.”

To check, remove the tank and empty any collected water. Ensure the tank is securely reinserted before restarting the dehumidifier. If the tank isn’t full but your dehumidifier still isn’t collecting water, inspect it for leaks or cracks that might be causing the issue.

Best Rated Dehumidifiers

2. The humidity level is too low

Dehumidifiers rely on a certain level of humidity to function effectively. If the air in your home is already dry (typically below 40% relative humidity) your unit may not collect water because there simply isn’t enough moisture to extract.

“This is a good thing and not something to worry about!” explains Chris Michael. “For example, Meaco dehumidifiers are equipped with ‘Meaco Control Logic’ which means the dehumidifier will test the air every 30 minutes to check if the humidity has or has not increased. The dehumidifier will only start running again if the humidity has increased more than 3% above target.”

To determine whether this is the case, use a hygrometer to measure your home's humidity levels. If the levels are low, this may be a positive indication that your dehumidifier has already done its job. To keep your dehumidifier performing at its best, check its settings and adjust them to maintain a comfortable humidity range of 40–60%.

3. The room is too cold

Have you ever wondered whether dehumidifiers work in cold rooms? Many standard models struggle in low temperatures, particularly below 15°C. According to Chris Michael, poorly designed dehumidifiers often lack an internal cooling system suited to the British climate, leading to ice buildup on the coils. In even colder environments, such as garages below 10°C, this ice can turn into a solid block, completely disrupting their performance. “These models aren’t designed for colder climates like the UK and are best suited for summer temperatures around 27°C or even higher,” he explains.

To avoid these issues, look for a dehumidifier that’s specifically built to handle cooler conditions. Some models are designed with technology that prevents ice from forming, ensuring it continues to collect water even when temperatures drop. This is also where desiccant vs compressor dehumidifier technology becomes important. Compressor models tend to struggle in colder spaces because they rely on warm air to function, whereas desiccant dehumidifiers use a drying agent that works efficiently in low temperatures.

If you’re facing issues with your current unit, try moving it to a warmer part of your home or consider upgrading to a model better suited for cooler environments.

4. The filter needs cleaning

A clogged or dirty filter is one of the most common reasons why a dehumidifier stops collecting water, so it's a good idea to learn how to clean a dehumidifier to keep it running smoothly.

"Dehumidifiers contain filters that should be cleaned at least every two weeks to prevent dust, dirt, and other particles from clogging the internal parts," explains Chris Michael. Dirty filters can restrict airflow, forcing your dehumidifier to work harder and affecting its ability to collect water. To resolve this, try the following steps:

• Remove the filter and inspect it for dust or debris.
• If the filter is reusable, gently clean it with a vacuum or, if it’s washable, rinse it with warm water. For stubborn dirt on non-washable filters, wipe it with a slightly damp (not wet) cloth and allow it to dry completely before reinserting.
• Replace disposable filters as recommended by the manufacturer, usually every 6–12 months.

5. The dehumidifier isn't properly positioned

Where you place your unit plays a significant role in how well it collects water. Dehumidifiers are not designed for use in small spaces, so you should avoid placing the unit in tight corners or rooms smaller than 4m2. Placing a dehumidifier near a heat source can also reduce its efficiency.

To keep your unit collecting water, ensure it has adequate space around it for airflow and keep windows and doors closed to help your dehumidifier focus on removing moisture from the room it’s in. If you need to tackle damp and condensation in tiny spaces – like wardrobes or cupboards – you may want to consider alternative options such as silica gel packets or rechargeable dehumidifiers.

6. There could be a mechanical or electric fault

Mechanical or electrical faults can sometimes be the cause when your dehumidifier stops collecting water. Staying on top of routine dehumidifier maintenance and learning how to fix a broken dehumidifier can help you determine whether the issue is repairable or if it’s time to consider a replacement. Some common faults include:

• A broken compressor: The compressor is a critical component in most dehumidifiers, especially compressor-based models. It works by compressing and cooling the refrigerant to condense moisture from the air. If the compressor is damaged or malfunctioning, the entire dehumidification process is disrupted, leaving the unit unable to collect water at all. Unfortunately, this issue often requires professional repair or replacement.
• Refrigerant leaks: Refrigerant is essential for the cooling coils to condense water from the air. If there’s a leak, the refrigerant levels drop, reducing the dehumidifier’s ability to extract moisture. Symptoms of a refrigerant leak may include unusual noises or frost forming on the coils. Leaks should be addressed by a certified technician, as handling refrigerant requires specialised tools and training.

If your dehumidifier isn’t working after troubleshooting all these basic issues, consult the manufacturer’s support team or a qualified technician. If your unit is under warranty, repairs may still be covered. For older models, however, it might be more cost-effective to upgrade to a newer, energy-efficient model.

When I first started renovating my home, I was ready to take on the challenge of ripping out old carpets and updating a dated kitchen. But what I wasn’t prepared for was the constant battle with condensation on my windows and damp patches spreading across my walls.

Despite all my efforts, it felt like the moisture just kept coming back. After some research, I realised high humidity was the culprit, so I decided to face the problem head-on by investing in a dehumidifier to finally eliminate the damp and condensation for good.

Now, my home is drier, fresher, and infinitely more comfortable. Thanks to the dehumidifier, better ventilation, and a few other key changes, I’ve completely transformed my space. Here’s how I did it – and how you can too.

Pinpointing the problem areas

Damp and condensation aren’t just surface issues. Often, they come from excess moisture hanging around in the air. In my home, the most obvious sign something was wrong was the sheer amount of window condensation I noticed in the mornings. But the damp patches on walls told me the moisture was building up elsewhere too. To figure out where the problem was worst, I kept an eye on:

• Windows: Water droplets were forming on the glass, especially in the mornings.
• Walls: Cold corners and external walls were slightly damp to the touch.
• Clothes: Certain items in my wardrobe felt clammy to the touch, had a musty odour, and I even found mould on a pair of suede shoes.

After plenty of research, I invested in a hygrometer and quickly discovered the cause of my problems: high humidity levels and poor natural ventilation. To tackle the damp and condensation head-on, I realised I needed a three-pronged approach: improving ventilation, insulating my windows with secondary glazing, and finding the best dehumidifier I could get my hands on.

How to use a dehumidifier

Although a dehumidifier won't stop mould on its own, I knew it would help me reduce both humidity and moisture levels in my home – two important steps if I wanted to get rid of damp and condensation. So I opted for the ProBreeze 20L Premium Dehumidifier and found the following steps worked best:

• Placement: I put the dehumidifier in the bedroom first, as that’s where the damp was most noticeable. Keeping doors closed made it more effective at targeting the moisture in one space at a time. Eventually, I purchased another dehumidifier to place in my home office and I occasionally rotated these into other rooms, like the kitchen, whenever I was drying laundry inside.
• Settings: I set my unit to maintain a humidity level of 50%, which seemed to hit the sweet spot for reducing condensation without making the air feel too dry.
• Running times: I ran my dehumidifier for about 6-8 hours a day, especially overnight when condensation was at its worst.

Ventilation and other techniques

While the dehumidifier did a lot of heavy lifting, I quickly realised it couldn’t do everything on its own. Ventilation turned out to be just as important in preventing damp and condensation from building up again.

Here are some of the additional steps I took to get on top of these issues:

• Opening windows: I started opening the windows for 10-15 minutes each morning – a technique often referred to as to as house burping – let out the stale, damp air. Even in winter, this small habit made a big difference.
• Using a window vacuum: Condensation on windows was a daily battle, but a window vacuum made it so much easier to remove excess moisture from these surfaces. A simple tool like this window squeegee from Amazon would also work well for this task.
• Extractor fans: In the kitchen and bathroom, I made sure to run extractor fans whenever I cooked or showered. This meant excess moisture wasn't lingering around.
• Drying clothes indoors: This was a major contributor for me. When I had to dry laundry indoors, I placed it near the dehumidifier, which helped absorb extra moisture.

What the expert says

Although these steps made a huge difference in my home, I also sought expert advice from Chris Michael, founder and managing director of Meaco, on using a dehumidifier to get rid of damp and condensation. These were his three top tips:

1. Get your dehumidifier placement right

“For general damp and condensation – place the dehumidifier in a central area such as the landing or hallway. Leave internal doors open and set your dehumidifier to reach a target between 50-55% relative humidity. The dehumidifier will draw moisture in from your whole home (as long as you have chosen the correct size of unit).”

2. Target problem areas

“If you have a problem area, place the dehumidifier closer to that area e.g. if you have a damp problem in a specific bedroom, it would be advisable to put the dehumidifier in that room with the door shut. This will speed up the removal of excess moisture from that room.”

3. Clean the filters every two weeks

"To make sure the dehumidifier works at optimal efficiency, it’s really important the filter is clean every 2 weeks. Lot’s of people forget to do this, which causes dust and dirt to build up in the filer and make its way inside the unit. Cleaning the filter ensures the dehumidifier performs most efficiently and quietly.”

FAQs

Does a dehumidifier fix damp permanently?

Not on its own. While a dehumidifier works by reducing moisture levels, it’s only part of the solution. To permanently fix damp, you’ll need to address the root cause. This could include repairing leaks, improving ventilation, or upgrading home insulation to prevent moisture from returning. For example, check for water ingress around windows, roofs, or exterior walls and seal any gaps.

Can a dehumidifier stop condensation?

Yes, a dehumidifier can be highly effective at stopping condensation by lowering the overall humidity in your home. This means there is less water vapour in the air to settle on cold surfaces like windows, walls, or mirrors. For the best results, pair your dehumidifier with daily practices like wiping down windows with a window vacuum and ventilating your space by opening windows or running kitchen and bathroom extractor fans.

One of the most common dehumidifier mistakes is neglecting to clean and replace filters regularly. This simple upkeep tip is key to keeping your dehumidifier running smoothly and performing at its best – so don't forget to show your unit some love and attention!

If you’re battling damp or mould issues at home, chances are you’ve been advised to invest in the best dehumidifier your budget allows. But while these appliances are often hailed as must-haves for managing humidity and preventing mould, have you ever paused to consider what the potential disadvantages of a dehumidifier might be?

Dehumidifiers are undeniably effective, but like any appliance, they aren’t without their limitations. From energy use to maintenance requirements, it’s worth considering the bigger picture before making your purchase. After all, understanding both the pros and cons will help you get the most out of your investment.

To bring you a balanced perspective, we turned to dehumidifier and air quality experts for their advice. Here’s what you need to know about the disadvantages of dehumidifiers – and how to navigate them with confidence.

5 disadvantages of a dehumidifier

1. Dehumidifiers consume a lot of energy without smart controls

"Dehumidifiers are designed to operate 24/7," explains Chris Michael, managing director at Meaco. "In fact, this is the only way to ensure the humidity in your home is maintained correctly." However, the cost of running a dehumidifier continuously can significantly increase energy bills, especially if the unit lacks energy-saving features.

Thankfully, many modern models now include smart controls that adjust automatically based on your room’s humidity. These settings allow the unit to turn off once normal humidity levels are reached, helping conserve energy while keeping your home comfortable.

That being said, most budget models and rechargeable dehumidifiers often lack these features. Without automatic controls, you’re left with two choices: running the unit continuously or turning it off entirely. Both options have drawbacks – either higher energy costs or leaving your home vulnerable to excess moisture.

2. Dehumidifiers can be noisy

Dehumidifiers can create a noticeable hum during operation, which might not bother everyone, but it can feel disruptive in quieter spaces like bedrooms, home offices, or living areas where you want to relax. While some people quickly tune out the sound, others may find it harder to ignore, particularly if the unit is running constantly or at a higher fan speed.

Fortunately, you don’t have to resort to soundproofing your home. Look for models that are certified by Quiet Mark, which are specifically designed to operate quietly without sacrificing performance. Placement can also make a big difference. Keeping your dehumidifier on a soft surface or away from walls can help absorb vibrations and reduce noise.

3. Dehumidifiers require regular maintenance

Another drawback of owning a dehumidifier is the upkeep required to keep it running smoothly. Regular dehumidifier maintenance is a must. This includes simple tasks like emptying the water tank, cleaning filters, and keeping the unit dust-free.

Neglecting to clean your dehumidifier or replace its filters on time are common dehumidifier mistakes that can take a toll on your appliance. Over time, these oversights can lead to reduced performance, higher energy bills, and even unpleasant surprises like musty odours or ice building up inside the unit. Keeping up with routine care ensures your dehumidifier will run efficiently and continue to be an asset in your home, rather than a source of frustration.

4. Dehumidifiers can make indoor air too dry

"Running a dehumidifier continuously may lead to overly dry air, which can cause issues like dry skin, respiratory irritation, and even damage to wooden furniture or floors," cautions Glenn Wiseman, Sales Manager at Top Hat Home Comfort Services.

Extended use of a dehumidifier can also disrupt the moisture balance in your home, especially if the air is already on the dry side. Maintaining the right humidity is essential for healthy, comfortable indoor air. Houseplants, for instance, can suffer in overly dry conditions, with leaves turning brown or crispy when moisture levels drop too low.

A hygrometer – such as the Temtop Air Quality Monitor from Amazon – is an easy, affordable tool to help you monitor your home’s humidity levels and avoid stripping the air of essential moisture.

5. Not all dehumidifiers work in cold climates

Most dehumidifiers work best in warmer, more temperate conditions, which means they can struggle in cold or unheated areas like basements during winter. Compressor models, in particular, are prone to freezing up as temperatures drop, causing a noticeable dip in their efficiency.

"Poorly designed dehumidifiers lack an internal cooling system that has been designed for the British climate, so when used in temperatures below 15°C, they can start to accumulate ice on the coils," explains Chris Michael from Meaco. "In even colder environments, such as garages below 10°C, this ice buildup can turn into a solid block, disrupting the unit's performance."

In these cases, a desiccant dehumidifier could be the better option, as it’s designed to work efficiently in cooler temperatures. When choosing between a desiccant vs. compressor dehumidifier, think about the conditions of the space you’ll be using it in to find the right fit for your home.

6. Dehumidifiers aren't suitable for all spaces

While dehumidifiers are incredibly useful in the right environment, there are some spaces where they simply aren’t suitable. For instance, "it's against the law to put a dehumidifier in a space less than 4m²," explains Chris Michael. Small areas like cupboards or compact rooms are not only impractical for dehumidifiers but can also be unsafe.

Bathrooms are another no for dehumidifiers. "Dehumidifiers are not IP rated and therefore cannot be used in a bathroom," Chris adds. "This is why British bathrooms do not have plugs in them – electrical appliances and water just don’t go well together!"

Instead of using a dehumidifier, consider improving your bathroom ventilation with a bathroom extractor fan or by keeping the bathroom door open while placing a dehumidifier in the adjacent hallway.

7. You may actually need an air purifier

While a dehumidifier is great for removing excess moisture, it won’t tackle allergens, pollutants, or odours that can impact indoor air quality and cause discomfort. For issues like dust, pet dander, or smoke, an air purifier may be a better choice.

Deciding between an air purifier vs dehumidifier comes down to your specific needs. However, if you’re dealing with both excess humidity and air quality concerns, hybrid 2-in-1 models are available that can handle both tasks. These appliances control moisture levels while filtering the air, but they tend to come with a higher price tag and may not perform as well as standalone devices.

8. Dehumidifiers won't fix serious underlying mould or damp issues

While a dehumidifier can certainly help manage moisture, it’s not a cure-all for more severe structural issues like leaks, mould, or poor home ventilation.

"To believe that dehumidifiers will solve underlying issues is incorrect," states James Longley, managing director at Utility Bidder. "While these appliances are useful for lowering moisture levels in the air, which in turn helps reduce condensation and mould, other steps are necessary to keep on top of issues such as mould growth. For example, creating good airflow by opening windows when the dehumidifier is switched off and taking shorter showers to minimise steam can make a significant difference."

If you’re dealing with persistent dampness or mould in your home, it's a good idea to consult a professional to identify the source of the issue. Fixing leaks, improving home insulation and making structural repairs are often a more permanent – and necessary – solution than relying solely on a dehumidifier.

FAQs

What are good alternatives to using a dehumidifier?

"If you're just experiencing a temporary spike in your humidity levels, there’s no need to buy and use a dehumidifier," explains John Jordan president at Integrity Heating & Cooling Inc. "In such situations, it’s better to use less heavy duty solutions, something like budget-friendly moisture absorbers that come in buckets or hanging moisture absorbers."

"If your goal is to reduce humidity in your home, make the air move by keeping the interior doors open, running ceiling fans, and opening windows for 10 minutes every day," John continues. This process is often referred to as 'house burping'. "When the air is stagnant and not circulating, moisture from everyday activities like cooking, showering, and even breathing can’t disperse, leading to humidity buildup."

Shop the best dehumidifier alternatives

For all the disadvantages of a dehumidifier, there are plenty of advantages to consider too. For example, a dehumidifier can be used to dry clothes and to clear window condensation.

Do dehumidifiers work in cold rooms is a question you may be asking yourself if yours isn't performing quite as well as you'd hoped. However, the answer is a little more complicated than a simple yes or no.

While there is some element of truth in the fact that temperature can affect performance, it comes down to a number of different factors including the type of dehumidifier, its size and where you are using it.

We asked experts do dehumidifiers work in cold rooms so you can make sure you have the best dehumidifier for the job, and know how to make it work well.

Do dehumidifiers work in cold rooms? Why temperature matters

Dehumidifiers come in two main types – desiccant vs compressor. It's important to understand how do dehumidifiers work before purchasing one, as temperature plays an important part in which one works best in colder spaces.

While both remove moisture from the air, a compressor dehumidifier works using coils and a refrigerant system – much like your refrigerator, but a desiccant dehumidifier is different.

"Temperature has a significant impact, particularly for compressor dehumidifiers," confirms Chris Micheal, co-founder managing director of Meaco. "The colder the room, the less efficient it becomes.

"Compressor dehumidifiers rely on the cooling coils inside to condense water from the air, but in colder rooms, the temperature difference between the coils and the air is reduced, making condensation less effective," he explains. "And, if the room is too cold, the coils can also freeze – although compressor dehumidifiers do have a defrost mode to try to prevent this from happening."

Adele Brennan, home electricals buyer at VonHaus explains why dessicant dehumidifiers are less impacted by a sudden drop in temperature.

"In terms of desiccant dehumidifiers, these models can work effectively in cooler temperatures, as well as warmer temperatures, as they don’t require a refrigerant system to work," Aneesa says. "Instead, they use an absorbent material to pull moisture from the air."

"This chemical absorption process works consistently regardless of temperature," adds Chris Michael.

When is it too cold for a dehumidifier?

If the temperature has massively dropped outside, or you've got a problem with your heating that means your home is like an ice-box, it could be time to switch the dehumidifier off until it gets warmer. Both types of dehumidifier have a point at which they will no longer be able to work properly.

"Compressor dehumidifiers typically struggle below 15°C," says Chis Michael, "and can stop working entirely around 5°C due to freezing."

"Below 1°C is considered too cold for a desiccant dehumidifier," advises Anessa Khan, although Chris notes how they have been known to keep on working even below freezing.

What room temperature is best for a dehumidifier?

In terms of what is defined as cold, the general advice is that a constant room temperature below 10°C is the point at which you need to switch to a desiccant dehumidifier.

Wondering which dehumidifiers is best for cold rooms? "Desiccant dehumidifiers, perform well regardless of the temperature," says Chris Michael, "making them a great choice for colder environments such as garages, unheated conservatories, basements or even boats."

For inside the home, where the temperature is kept higher, in particular during the winter when it's important to stick to the advised minimum house temperature to avoid issues with mould, damp and condensation, a compressor dehumidifier however will be the better option.

"Any size compressor dehumidifier is useful for when room temperatures are above 15°C," confirms Anessa Khan, although for the best energy efficiency, "compressor dehumidifiers work best in warmer conditions, ideally above 20°C, a typical temperature in a heated UK home," says Chris Michael.

But, if you've already invested in a desiccant dehumidifier, and your room temperature sits between the 15-20°C range don't worry, as unless you keep your home way above this temperature, it will still do the job.

"Desiccant dehumidifiers are very durable," confirms Anessa, "and are effective in most conditions, and will work in temperatures between 1-20°C."

There can also be an added benefit of using a desiccant dehumidifier in rooms where the temperature sits between 10-20°C. As they push hot air back out, they can also help to heat the room. And while they are a little more expensive than compressor dehumidifiers to run, this cost could reduce the need to turn the heating on so frequently.

Discovering a mould problem in your home can be both frustrating and overwhelming, especially when it comes to figuring out how to eliminate it for good and prevent it from coming back. With various types of mould lurking in damp spaces, many people turn to dehumidifiers to stop the spread. But can they really eliminate mould, or are they just one part of the solution?

While the best dehumidifiers are excellent for maintaining healthy humidity levels, they’re often misunderstood. Some homeowners believe they’ll completely rid a home of mould, while others expect them to work miracles without addressing deeper issues. To clear up the confusion, we’ve asked industry experts to help debunk the most common dehumidifier myths.

Here’s the truth about dehumidifiers and mould, straight from the professionals.

Myth 1: A dehumidifier will eliminate existing mould

Many believe that a dehumidifier will magically remove mould from walls, furniture, or carpets. In reality, dehumidifiers help prevent mould from spreading but can’t tackle mould that’s already present. As Chris Michael, managing director of Meaco, explains, “A dehumidifier can stop patches of mould from getting larger, but it will not make it go away.”

Mould removal requires physical intervention, such as scrubbing surfaces with mould-specific cleaners for smaller areas like bathroom grout or window sills. For more severe cases, such as mould embedded in carpets, professional remediation services may be necessary, using specialised equipment like HEPA vacuums and antimicrobial treatments to remove mould and prevent it from returning.

Michael Rubino, author of The Mould Medic, echoes this point: “If there’s an existing mould problem, a dehumidifier will not help resolve it. It can be used to help eliminate opportunities for more growth elsewhere, but that’s the extent to which it’s effective.”

Myth 2: Dehumidifiers work alone to prevent mould

Dehumidifiers are an excellent tool for managing indoor humidity, but they’re not a one-stop solution for getting rid of mould. James Longley, managing director at Utility Bidder, explains: “A dehumidifier alone won’t solve mould issues. While it helps reduce moisture and mould risk, steps like improving airflow are essential.”

Michael Rubino agrees, emphasising the need for a combined approach: “The ideal humidity level in a home should be between 35 and 50 percent to prevent mould growth. Dehumidifiers help maintain this level, but they’re ultimately a supplementary tool.”

He continues: “Effective mould remediation means fixing the source of the problem, removing existing mould, and eliminating all sources of contamination.” Simple habits, like using bathroom extractor fans and letting your home breathe via 'house burping', can make a big difference and complement a dehumidifier’s work. .

Myth 3: A dehumidifier will stop all mould growth regardless of the source

The source of damp or condensation in your home will determine how effective a dehumidifier will be. If a mould or mildew problem is caused by high humidity, a dehumidifier can certainly help create a less hospitable environment for it. However, if your mould originates from other issues, such as leaks or poor drainage, a dehumidifier won’t solve the problem.

“Mould is caused by an excess of water within an organic hygroscopic material,” Michael Rubino explains. “If it is from a leak, then a dehumidifier could not have prevented it in the first place.”

This distinction is critical for homeowners looking to address persistent mould problems. If the root cause of moisture – be it a leak, condensation, or poor home ventilation – isn’t addressed, mould is likely to return, even with a dehumidifier running continuously.

How does a dehumidifier help with mould?

While dehumidifiers aren’t a cure-all, they’re a powerful tool in your mould-prevention arsenal. By maintaining humidity levels between 35% and 50%, they help prevent the conditions that mould needs to thrive. Michael Rubino explains: “Once you have mould, it will only grow larger if the relative humidity at its surface is greater than 68%. A dehumidifier can help prevent this from happening.”

“Mould can grow at a relative humidity of 60%, so the goal is to keep your home below that level," he continues. Placed strategically in high-risk areas – like bathrooms, kitchens, or basements – and combined with proactive measures, dehumidifiers can make a significant difference in creating a healthier home environment.

FAQs

Does it matter where you place your dehumidifier?

"Dehumidifiers reduce moisture levels circulating indoors, but they are only effective if they are positioned in the correct place," explains James Longley, managing director at Utility Bidder. "The appliance works to the best of its ability in smaller spaces, such as a bedroom or living room. If a dehumidifier is placed in a more open area, it won’t be able to remove as much moisture compared to if it was placed in a more confined room."

Can a dehumidifier kill mould spores?

No, a dehumidifier cannot kill mould spores. It works by reducing moisture levels in the air, which helps prevent mould from spreading or thriving. However, existing mould spores require physical removal or treatment with mould-specific cleaners or professional remediation to eliminate them completely.

Don’t want to spend a fortune fixing a minor mould problem? In addition to dehumidifiers, there are plenty of budget-friendly products to get rid of mould. When choosing a dehumidifier, consider the extent of your home's issues. A budget dehumidifier vs premium dehumidifier could save you money if a smaller unit meets your needs.

Fed up of steamy bathroom mirrors and wet slippy floors? If you're thinking of using your electrical dehumidifier for bathroom condensation then you could be making a fatal mistake, say the experts.

While the moisture removing prowess of the best dehumidifiers is always worthy of recognition, there's a time and place for using them, and the bathroom isn't it.

Although non plug-in moisture absorbers are of course considered safe, a powered dehumidifier that mechanically extracts moisture from the air is a no-no. Even if it's wall-mounted and wired.

Here's why the experts say no to a dehumidifier for bathrooms and the correct guidance for using one.

Why using a dehumidifier in a bathroom isn't safe or legal

Steamy showers or baths and hard cold surfaces such as bathroom tiles are the perfect combination for condensation and moisture to build up in your bathroom. With the correct bathroom ventilation and the best bathroom extractor fan, the theory is you shouldn't need any extra methods to remove the excess water that builds up.

But what if you don't? It could be tempting to pop in your dehumidifier to extract any leftover moisture to prevent issues such as damp walls or ceilings. However, when we asked the experts if there are any types of electrical dehumidifiers that are safe to use in bathrooms, their answer is perfectly clear.

"No, it is illegal and not safe to use electrical appliances in the bathroom in the UK," warns Chris Michael, founder and managing director of Meaco.

“Controlling humidity levels in your bathroom is crucial to prevent condensation, damp, and mould," agrees Andy Simms, building expert at MyBuilder.com, "and although it may feel like a dehumidifier is a good way to combat moisture damage; it’s powered by electricity and is therefore not safe."

Alternatives to using a dehumidifier in a bathroom

So if you can't use a dehumidifier for bathroom moisture removal, what can you do instead? Here's what the experts recommend.

1. Natural ventilation

“A free alternative to a dehumidifier is to use natural ventilation. Keep your windows and doors open while you shower or bath – when possible – to allow moisture to escape," says Andy Simms. "This is very important to do especially after a shower/bath to help airflow and dry out the room quickly."

Alternatively, "open the window for ten minutes after bathing or showering," suggests Chris Michael. A more practical solution if your bathroom door opens onto a communal area such as a hallway, or you have an ensuite bathroom. Letting the moisture out of the bathroom into the bedroom where there are lots of fabrics and often carpets isn't entirely practical either – especially when you consider the fact your carpet could already be home to invisible mould.

2. Install an extractor fan

"If your bathroom doesn’t have a window, or you can’t keep the door open for long periods, the most practical and effective solution is hiring an expert to install an extractor fan in your bathroom to remove condensation and help prevent bathroom mould," says Andy Simms. "Or, if not an extractor fan, another great alternative is to install a ventilation grille," he suggests.

But, as well as installing an extractor fan, you also need to make sure you use it properly, says Chris Michael.

"The effectiveness of bathroom extractor fans depends on how well maintained the extractor fan is, whether it is the right size for the bathroom and also whether it is used," he says, noting how lots of people turn them off because of noise or energy consumption fears.

3. Lower the temperature of your showers

“Having a cooler shower is another alternative to using a dehumidifier for bathroom condesation," suggests Andy Simms, "with the added bonus of saving you money on your heating bills, which is very important in today's cost of living crisis.

"By lowering the temperature, the bathroom won’t get as hot and the air will hold less moisture reducing condensation.”

4. Invest in a mirror with a demister pad

If condensation on your mirror is the main problem, consider switching to one of the best bathroom mirrors with lighting. Many come with inbuilt demister pads which will help keep your mirror steam free allowing you to get ready without you having to constantly wipe the mirror clean.

How to use your dehumidifier to combat bathroom condensation

The good news is, if you have a dehumidifier in your home to help with damp or mould issues, you can use it to help with bathroom condensation, as long as you use it correctly.

"To dry a bathroom with a dehumidifier all you have to do is plug it in outside the bathroom and leave the bathroom door open after a bath or shower with the dehumidifier by the entrance to the bathroom, but still outside it," says Chris Michael. "The damp air will naturally migrate towards the dehumidifier."

And as tempting as it can be to pop it inside the room, even if there's no-one in there and no water being run, it's still not advisable warns Chris.

"Don’t encourage any use of a dehumidifier in the bathroom," he clearly states. "People can get seriously injured or killed by mixing bathrooms and 240 volts."

FAQs

Can you use a wall mounted dehumidifier in the bathroom?

Although wall mounted dehumidifiers may seem like a potential solution to choosing the right dehumidifier for bathroom condensation, this still isn't a safe or viable solution advises Chris Michael.

"This is not practical as plugs and sockets need to be three metres from a bath, shower or wash basin," he explains, "furthermore, domestic dehumidifiers do not have the correct IP rating for use in a wet area."

It's not surprising to hear that dehumidifiers could be hard to find in the next few weeks, with the sudden snap of cold weather highlighting the need for one in your home.

Perfect for battling condensation, damp and mould, concerns are growing that we could potentially face a similar dehumidifier shortage to the one seen at the start of this year.

Add to this the flurry of purchasing with Black Friday deals already being offered online, should you be concerned stores will run out, or are there still plenty of the best dehumidifiers available?

I've scoured online stores to find out what's in stock and where you can get a bargain.

Which dehumidifier do you need?

Choosing the right dehumidifier comes down to a number of different factors. The temperature of the room where you will be using it, what you will be using it for, how much moisture you need to extract each day and budget.

Not to be confused with cheaper moisture absorbers, dehumidifiers are electrical appliances that need to be plugged in to work. Mechanically extracting moisture from the air, they are perfect for dealing with window condensation, drying out basements or garages, drying laundry and helping to improve the overall ambient temperature of your home.

For colder spaces you'll need to use a dessicant vs a compressor dehumidifier as these are designed to work in lower temperatures. Minor levels of moisture can sometimes be tackled with smaller dehumidifiers, although in most cases, investing in a larger model will generally provide you with a more efficient solution.

Where to buy dehumidifiers

The good news is, we've searched the following sites for dehumidifiers, and there's currently stock available in them all. Some less than others, but nothing that would suggest you will struggle to buy one for now.

If you're looking for the best dehumidifier, the chances are you've looked at some of the prices of the electric models and wondered if they're really worth the expense. I know I certainly did when starting my dehumidifier research.

While the more expensive models do definitely work (the ones we've tested at Homebuilding & Renovating all did), not everyone has £150 to £300 available in the bank right now to spend on one.

It sparked the question as to whether cheaper options for under £40 were worth buying or whether it was a false economy, so we decided to put this to the test.

I started with the UniBond Aero 360º Moisture Absorber in my son's bedrooms and then progressed to the Russell Hobbs Mini Compact Dehumidifier (currently only £39.99 on Robert Dyas for Black Friday) for the smallest bedroom.

Testing £9.96 'dehumidifier' moisture absorbers

When I moved into my Grade II listed apartment, the single glazed sash windows were a concern, but one I eventually hope to overcome either with secondary glazing or even new windows. However, as neither of those are an immediate option, the issue of window condensation rears its ugly head as soon as the temperature drops.

Coming across a number of positive reviews about the UniBond Aero 360º Moisture Absorber that is on offer on Amazon for £9.69 for Black Friday, I purchased some to use in my son's bedrooms. The smaller room has a large sash window, the other a double and single casement timber window. Neither room shows any other signs of damp, just window condensation.

The UniBond Aero 360º Moisture Absorber comprises a plastic container with a replaceable blue disc that absorbs the water, releasing it into the container. You empty the lower part of the container as it fills and eventually the disc disintegrates at which point you replace it.

Another of the Homebuilding & Renovating team, also reviewed this product, sharing how a moisture absorber helped her condensationher windows, leaving me hoping I'd have the same results in my home.

I found that there's no doubt that the units collect moisture as I ended up regularly decanting water from them. However, I must have had a lot more moisture content in the air in my home compared to my colleague, as for me both moisture absorbers did not work on the windows as much as I had hoped.

The absorber in the larger room surprisingly worked better, while the absorber in the smaller bedroom, which I had assumed would be more effective, collected less moisture.

In the end, I disposed of both products – something that wasn't ideal given they are plastic and not really environmentally friendly.

Testing a £39.99 Russell Hobbs desktop dehumidifier

Lidl's middle aisle is often the source of bargains, and I thought I'd snagged one when I spotted the Russell Hobbs Mini Compact Dehumidifier on offer soon after throwing out the moisture absorbers. According to the product details, it claims to work in rooms that are around 15m2.

Unboxed and plugged in according to the instructions, I was excited to see the results the following morning.

Sadly, after a week of testing, it seems the issue this time was with the power of the extraction. Despite the window being covered with condensation, the water container barely filled up some nights. In terms of location, it was placed on my son's bedside table, next to the window so it should have absorbed the water he'd produced breathing, as well as the condensation that had formed on the window.

As it collected so little moisture, although the electricity costs to run it were minor, it simply wasn't weren't worth leaving on.

Cheap fix vs investing your money

Although trying out the options hasn't been a hugely costly experience, the reality is that I've spent around £60 on budget and small dehumidifier solutions that could have been put towards the cost of a larger dehumidifier sooner.

While my windows don't appear to have sustained any long term damage, (partly due to the fact that I also used the Beldray Cordless Window Vacuum last winter to remove the condensation each morning), this year I've used the De'Longhi and MeacoDry dehumidifiers in mine and my son's bedrooms, which has had remarkable results.

Window vacuums are effective at removing condensation, albeit a little hard to use on small paned windows, but it still means moisture builds up overnight which isn't great for the people sleeping in the rooms, or the long term condition of the wooden windows.

Do I think small dehumidifiers and moisture absorbers do what they say they will? It's impossible to deny they collect water – the results are visible. But are they worth it for stopping condensation altogether?

In my experience, if you've genuinely got an issue with condensation or above normal humidity levels in your home, I'd recommend you save up and spend it on a more expensive model.

Having tested two larger models myself, the Delonghi DEX212F 12L Tasciugo Ariadry Dehumidifier and the MeacoDry ABC 12L dehumidifier, I have no hesitation in recommending you buy either one of these instead of the cheap alternatives I've tested here.

Anything else will be false economy as small solutions won't fix big problems.

FAQs

How do cheap dehumidifiers and moisture absorbers work?

If you're wondering how do dehumidifiers work, in basic terms they are defined as a product that removes moisture from the air.

While a full-size dehumidifier will do this by pulling air in, cooling it and collecting the condensate, products like dehumidifier doorstops and rechargeable dehumidifiers instead use a physical moisture absorbing substance to absorb the moisture from the air. This substance can be either:

• Silica gel: A solid porous ball that absorbs moisture by osmosis
• Calcium chloride: A solid salt turns into a saline mixture when it absorbs water
• Activated charcoal: This works by molecules of moisture being attracted to it

Tried a dehumidifier and still not getting the results you'd hoped for? You could be using the wrong type of dehumidifier. Find out more in our guide to dessicant vs compressor dehumidifiers. And if the problem with condensation is mainly in your bathroom, be sure to buy one of the best bathroom extractor fans to prevent moisture build up on a daily basis.

If your home feels damp or you’re fighting a constant battle with musty, lingering odours, there’s a strong chance that excess humidity is wreaking havoc behind the scenes. Recognising the signs you need a dehumidifier can make a real impact, as moisture buildup often creeps in undetected, negatively affecting indoor air quality and even damaging your health if left unchecked.

Thankfully, investing in one of the best dehumidifiers can make all the difference in improving your indoor environment. These helpful appliances work to reduce excess moisture, leaving your home feeling fresher and your air cleaner.

So, how can you tell if your home needs a dehumidifier? Below, we outline the telltale signs that your space could benefit from one of these helpful appliances, and why ignoring these red flags might lead to costly issues down the line.

The signs you need a dehumidifier

"A cold-feeling house, dusty smells in the air, clothes taking ages to dry, and mould or damp on your walls are all strong indicators that excess moisture is becoming a problem in your home, and a dehumidifier may be needed to restore a healthy indoor environment," explains Chris Michael, founder and managing director of Meaco. Recognising these signs early can save you time, money, and even prevent potential health concerns.

1. Persistent condensation on windows

"One of the most obvious signs you need a dehumidifier is waking up to condensation on your windows in the morning," says Chris Michael from Meaco. While misty windows may seem like a minor inconvenience, they can actually signal a bigger issue lurking in your home’s air.

Condensation forms when warm, moist air meets a cooler surface, like your windows, and turns into water droplets. This moisture might seem harmless at first, but over time, it can lead to damp walls, peeling paint, and even encourage mould and mildew growth in hidden or poorly ventilated areas.

By removing this excess moisture from the air and maintaining balanced humidity levels, a dehumidifier can clear window condensation and create a drier indoor environment where condensation is less likely to form and damage your home and belongings.

2. Musty smells that won’t go away

"If you notice a musty or damp smell that lingers in multiple areas of your home, it could be a sign of excessive humidity and mould growth," explains Polya Petrova, a cleaning specialist from Fantastic Services. This odour is often most noticeable in basements, bathrooms, and cupboards where poor ventilation or high levels of moisture are typically present.

Mould and mildew, which thrive in damp conditions, are often the culprits behind musty smells and their spores can permeate soft furnishings, carpets, and even walls, making the odour hard to shift with surface cleaning alone. Thankfully, a dehumidifier can help lower the humidity in the air and create an environment where mould and mildew will struggle to survive. Over time, this can help banish musty smells for good.

Top Tip: If bad odours are a recurring issue in your home, you might also consider buying an air purifier to work alongside your dehumidifier. Some models of dehumidifier combine both functions, like the MeacoDry Arete® One 10L dual Dehumidifier & HEPA air purifier from Amazon. These units not only manage moisture but also help filter out airborne particles, leaving your home fresher and free from unwanted smells.

3. Mould or mildew spots on walls or ceilings

Spotting mould on a ceiling or on your walls is a clear sign that it’s time to invest in a dehumidifier. Mould thrives in damp, poorly ventilated spaces, and when it takes hold indoors, it can be more than just an eyesore. Mould in houses has the potential to cause respiratory problems or trigger allergies, especially if left unchecked.

Depending on the type of mould, you might notice black, white, or green spots creeping across surfaces, often in hidden corners, bathrooms, or basements where moisture levels run high. Thankfully, a dehumidifier can help manage this issue by lowering the humidity levels that mould needs to grow and thrive. By creating a drier environment, a dehumidifier helps control moisture and prevent new mould from developing.

However, for a dehumidifier to be truly effective, it’s important to first remove existing mould at its source to avoid ongoing contamination. You should also regularly clean your dehumidifier’s filters, as this helps keep the appliance in top shape and ensures it isn’t inadvertently spreading mould spores back into your home.

4. Peeling paint or bubbling wallpaper

Paint and wallpaper that peels or bubbles is a clear indicator of moisture trapped in your walls. This is especially common in high-humidity areas like kitchens and bathrooms, where steam and condensation can easily build up and wreak havoc. Over time, trapped dampness can weaken the integrity of your home’s finishes, and in older homes, it can even lead to more significant structural issues if not addressed.

A dehumidifier is particularly useful in these cases because it actively reduces the moisture in the air, helping to prevent damp from settling into walls and other surfaces. For smaller, enclosed spaces where humidity issues persist, a desiccant dehumidifier is a good choice. Unlike traditional refrigerant models, desiccant dehumidifiers use absorbent materials to pull moisture directly from the air, making them highly effective in cooler rooms or spaces with poor ventilation.

5. Allergy symptoms are worse indoors

"If you or your family members experience increased allergy symptoms, such as sneezing, coughing, or asthma attacks, it could be an indication that the air quality has been compromised by excess moisture," explains Polya Petrova from Fantastic Services.

With a dehumidifier working to keep your home’s humidity in check, you might notice the air feeling lighter and your allergy symptoms diminishing over time. When combined with an air purifier and regular vacuuming, a dehumidifier can help you breathe easier and enjoy a more comfortable living space, especially during hayfever season.

6. Clammy or damp feeling air

If your home has a heavy, damp feeling – especially in basements, bathrooms, or laundry rooms – this could be a sign that your home is too humid and requires a dehumidifier.

To check if humidity is the root cause of these issues, Polya Petrova recommends using a hygrometer to measure your indoor humidity levels. She explains, "If you home's humidity is consistently above 50-60%, it's a strong indicator that your home would benefit from dehumidification, as well as improved ventilation."

7. Finding evidence of water stains

Water stains on walls or ceilings are another telltale sign that your home could benefit from a dehumidifier. Over time, these stains can develop into more than just a cosmetic issue. These unsightly marks often point to excess moisture seeping into your home’s structure, and if left unresolved, they can eventually lead to issues like weakened plaster and even wood rot. The good news is that a dehumidifier can help prevent further water stains from appearing by managing moisture levels and helping create a drier environment.

8. Rust on metal surfaces or fixtures

Rust on indoor metal fixtures, like hinges or pipes, is a clear indicator of high humidity levels. Excess moisture in the air can lead to corrosion on metal surfaces, potentially resulting in costly repairs or replacements. Running a dehumidifier in affected areas can help manage this humidity, but Chris Michael from Meaco cautions against using them directly in bathrooms: “Dehumidifiers are not IP rated and therefore cannot be used in a bathroom (this is why British bathrooms do not have plugs in them).” Instead, place your dehumidifier in an adjoining hallway with the bathroom door open to allow moisture to disperse effectively.

9. Wooden furniture or floors warping

When wood absorbs moisture from the air, it can swell, crack, and even become misaligned, impacting everything from hardwood floors to wooden doors and furniture. This is particularly common with loft condensation, where moisture can quietly accumulate unnoticed until damage has already occurred to structural beams or panels.

By maintaining stable humidity levels, a dehumidifier can protect your home’s valuable wood surfaces, keeping floors level, furniture intact, and helping you avoid costly repairs from prolonged moisture exposure.

10. Your home feels much colder than usual

If your home feels chillier than usual, it could be signalling something more serious than a drop in outside temperature. High humidity often makes indoor spaces feel cold and damp, even when the heating is turned up. This happens because moist air draws heat away from surfaces, creating a lingering coolness that’s hard to shake. By reducing excess moisture, a dehumidifier helps your home retain warmth, resulting in a drier, cosier environment that doesn’t rely as heavily on constant heating. Not only can a dehumidifier make your home feel warmer, but it can also lead to energy savings by reducing the need for extra heating.

Regular dehumidifier maintenance is essential if you want to keep your appliance in top condition. Cleaning or replacing its filters when needed will help keep your unit running efficiently, ensuring it’s up to the task of managing your home’s humidity levels for years to come.

If your home struggles with high humidity, damp, or condensation, a dehumidifier might be just what you need for a fresher, more comfortable space. But even the best dehumidifier can fall short if it’s not used correctly. To get the most out of these helpful appliances, you should try to avoid the most common pitfalls that homeowners encounter.

Selecting the wrong model or frequently adjusting settings are just a couple of mistakes that can keep your dehumidifier from working as well as it should. These small mishaps can drive up energy bills and, in some cases, even contribute to structural issues around your home.

To help you get the best performance from your appliance, we've outlined the most common dehumidifier mistakes that homeowners make and explained how to avoid them.

Common dehumidifier mistakes

1. You aren't running the dehumidifier consistently enough

Not a lot of homeowners realise that dehumidifiers are designed to operate 24/7. In fact, according to Chris Michael, founder and managing director of Meaco, this is the only way you can ensure the humidity in your home is maintained correctly.

"While it might seem like saving energy, running a dehumidifier only 2-4 hours per day isn’t effective," explains Chris. "Dehumidifiers are designed to run continuously to monitor and respond to changes to humidity levels throughout the day. So switching your dehumidifier on and off can allow moisture to build up, increasing your humidity levels and reducing your overall comfort."

Since the majority of dehumidifiers are incredibly energy-efficient, running them consistently shouldn't negatively impact your energy bills. However, you will likely notice a marked improvement in your indoor air quality if you allow your device to function as it was intended to.

2. You're using the wrong type of dehumidifier for your home

"Selecting the right model for your space is crucial," urges Chris Michael. "Using the wrong type will prevent the dehumidifier from operating efficiently, leading to poor moisture control. That's why it's worth learning the difference between a desiccant vs compressor dehumidifier."

"Compressor dehumidifiers work best in temperatures above 10-15°C and are less effective in colder conditions," he explains. "For spaces below 10°C, such as basements or garages, a desiccant dehumidifier is ideal, as it performs well even down to 1°C."

It's also a good idea to consider what other features your dehumidifier needs. For example, if you regularly dry your laundry inside, look for a dehumidifier that helps dry clothes with a built-in laundry mode, such as the electriQ 12L Quiet Low-Energy Smart Dehumidifier from Appliances Direct.

3. You're placing the dehumidifier in the wrong location

According to John Jordan, president at Integrity Heating & Cooling Inc, tucking a dehumidifier against a wall or placing it in a corner is not the best setup: "For proper airflow, give the unit at least half a metre of clearance on all sides – this way, it can do its job more effectively."

Ideally, you should position the dehumidifier near the centre of the room or in an open area where air can flow freely. You should also avoid placing it near heat sources, such as radiators or portable heaters, as these can interfere with the humidity readings and cause the unit to cycle on and off unnecessarily.

4. You're changing the settings too often

As tempting as it may be to try out all the buttons on your control pad, John Jordan cautions against frequently adjusting a dehumidifier’s settings. "Constantly changing the setting can cause the unit to cycle on and off more often, which increases wear and energy use," he explains. "The ideal approach is to set your dehumidifier to around 45% and let the unit work until the desired humidity level is reached. By leaving it at a consistent setting, you can avoid unnecessary energy consumption and wear, while maintaining a balanced indoor climate."

5. You haven't cleaned your dehumidifier in months

While these appliances are relatively low-maintenance, they still need to be kept clean to function properly, making regular dehumidifier maintenance a must. Chris Michael from Meaco recommends cleaning the filter at least every two weeks to prevent dust buildup and inspecting the coils for any frost or dust at the same time. If you’re using a drainage hose, make sure it’s clear and properly connected to avoid clogs.

To prevent mould and bacteria buildup, rinse your dehumidifier tank every week with mild soap and warm water. For a deeper clean, add a few drops of white vinegar, let it sit for a few minutes, then rinse thoroughly. You should also wipe down the exterior body of the unit occasionally.

"For households with pets, smokers, or high levels of pollution, more frequent cleaning is recommended," says Chris. "Failing to clean the filter can reduce airflow, damage the dehumidifiers internal parts and reduce its overall performance."

6. You've owned your unit for years and never changed the filter

As well as cleaning your dehumidifier filter on a regular basis, you should also get into the habit of replacing these filters when needed. Over time, filters become saturated with dust, dirt, and other particles that cleaning alone will struggle to remove. When left unchanged, these clogged filters can restrict airflow, forcing the appliance to work harder, use more energy, and risk internal damage that can break a dehumidifier.

Most manufacturers recommend replacing filters every 6-12 months, depending on your units usage and your indoor air quality. For homes with pets, smokers, or higher pollution levels (such as in cities), you may need to replace your filters more often.

FAQs

Why does ice form in a dehumidifier?

"Poorly designed dehumidifiers lack an internal cooling system that has been designed for the British climate, so when used in temperatures below 15°C, they can start to accumulate ice on the coils," explains Chris Michael, managing director of Meaco. "In even colder environments, such as garages below 10°C, this ice buildup can turn into a solid block, disrupting the unit's performance. These models aren’t designed for colder climates like the UK and are best suited for summer temperatures around 27°C or even higher."

Is it a mistake to use a dehumidifier and an air purifier in the same room?

According to John Jordan, president of Integrity Heating & Cooling Inc, "While air purifiers can be used in the same room as a dehumidifier, the two fans can often end up competing, creating turbulent airflow and making both units less efficient. The air purifier might even pull in the dry air from the dehumidifier, which stops the dehumidifier from reaching the room’s humid air effectively."

To prevent this from happening, make sure you place the dehumidifier in a spot with ample open space around it, ideally near the centre of the room or in a location where airflow won’t be obstructed by walls or furniture. Position the air purifier in a separate part of the room to avoid any interference with the dehumidifier’s airflow.

By avoiding these common mistakes and making a few simple adjustments, you can keep your dehumidifier running costs down, keep your appliance running smoothly, and you home free from moisture and damp issues.

If dehumidifier and doorstop aren't two words you'd normally put together, you're not alone. It wasn't something I'd come across either, or anything the team has seen when looking at the best dehumidifiers. But, having spotted it in Lidl's middle aisle I figured the £4.99 price tag was worth a punt. Living in a single glazed listed building I'm no stranger to condensation on my windows and couldn't be without my electric dehumidifiers.

Of course, the reality is that the term dehumidifier attached to a doorstop is a little bit of an oversell. In the same way as rechargeable dehumidifiers are essentially moisture absorbers, so is the doorstop.

But, at a bargain price of £4.99 and with claims to only take 6 minutes time in a 600W microwave to 'recharge', it felt like I had nothing to lose in buying one.

How does a dehumidifier doorstop work?

The Wenko Doorstop Dehumidifier from Lidl weighs 1kg and is a fabric covered doorstop containing moisture absorbent crystals. As the crystals absorb moisture from the air, the blue water droplet design on the front of the doorstop changes colour to show the saturation level.

Once saturated, the doorstop can be popped in the microwave, heated up to dry out the crystals and then it's ready to be reused.

It's similar in concept to rechargeable dehumidifiers such as these Aironic rechargeable dehumidifiers from Amazon which contain silica gel. Once the gel is saturated, you plug the units into charge for around 6-9 hours.

However, in general, when looking at how do dehumidifiers work , the more commonly seen electric versions work by extracting moisture from the air and collecting it in a water tank which you empty. They're a more effective solution if you have problems with window condensation or damp, and I'm also a big advocate of them for drying laundry.

Although I do have a tumble drier (I live in an apartment with no outdoor space so it's a necessary item for me), when weighing up dehumidifier vs tumble drier, other than towels, I dry everything else using the De'Longhi DEX212F dehumidifier, which I highly recommend.

Where to use a doorstep dehumidifier

Portable and not restricted to any one location, the dehumidifier doorstop from Lidl may well be sold for use on the floor, but as it doesn't need power, it could in theory be used anywhere.

Floors, shelves, inside wardrobes or on windowsills are all potential locations, although I was keen to see how much moisture seeps through the doorstop when it's fully saturated. Could this make the surface it's sitting on damp if you don't 'recharge' it quickly enough?

Have a problem with moisture in your car? Lidl are also selling a car version of this product which works in the same way. Shaped like a small beanbag, it’s designed to pop into the pockets of your car door. And although the term dehumidifier is perhaps a bit misleading, they do work confirms Amy Willis, Editor of Homebuilding.co.uk.

“I use these in my car and they do help reduce the condensation on the car windows,” she conifers. “I leave one in there for around a week at a time and then dry it out once it’s absorbed the moisture.”

Does this doorstep dehumidifier work?

Long-term, this dehumidifier doorstep clearly won't be a solution if you have a bigger problem with condensation and damp. Having previously tested small dehumidifiers and moisture absorbers to see if they are false economy, they really are no substitute for a full size electrical dehumidifier if you have moisture building up on a regular basis in your home.

But, has it contributed anything towards a reduction in moisture from the days I’ve tested it?

Used on my bedroom floor, the dehumidifier doorstop failed to make any noticeable difference to my window condensation, and neither did it change colour to suggest any moisture has been absorbed. All this despite the fact my windows did have a lot of condensation on them when I woke.

Perhaps part of the problem with this is that doors and windows are not always located next to each other. Mine are in fact at opposite ends of the room. However, tested again overnight on a chest of drawers next to the window, the same results were seen – or rather not seen. There was no change.

And finally, I popped it in my ensuite which has no window, just an extractor fan to see if it even soaked up any of the steam created by showering. Once again, the doorstop looks no different and shows no signs of moisture being absorbed.

My advice? If you want a doorstop, buy one you like the look of, rather than one that claims to be something it’s not. If you’re searching for something to help with condensation and damp, buy a good quality dehumidifier and it will be worth every penny.

Looking for other ways of helping to improve the humidity levels in your home? While house burping may sound like another dubious suggestion, this is a trick that does actually help improve your home ventilation and is infinitely more practical than it sounds.

Let’s face it, the only thing worse than accumulating piles of dirty laundry is the eye-watering cost of energy bills. And during winter, you can’t count on a bit of sunshine to air-dry clothes outside. So, how do you choose between a dehumidifier vs tumble dryer for this thankless task?

If you’re aiming to balance efficiency and cost, it’s worth looking into the best dehumidifiers on the market. These devices don’t just dry clothes – they also reduce moisture in the air, helping to prevent mould and mildew, making them a smart choice for the health of your home and laundry alike.

That said, the latest tumble dryers feature cutting-edge technology and are far more energy-efficient than older models, making them a strong contender for those who value speed on laundry day. Below, we break down both options to help you decide which is best for your home, your laundry, and your budget.

Dehumidifier vs Tumble Dryer

When it comes to drying clothes, both dehumidifiers and tumble dryers have their advantages. To help you make the right choice, we consulted a dehumidifier expert and a tumble dryer specialist to examine which appliance if best suited to your home and lifestyle needs.

How does each machine dry clothes?

How do tumble dryers dry laundry?

A tumble dryer dries clothes by using heat and motion, circulating warm air through the drum to evaporate moisture as the clothes are gently tumbled. Depending on your needs, you can choose between condenser vs heat pump tumble dryers.

A condenser tumble dryer work by heating air and blowing it through the drum, collecting moisture in a reservoir or draining it away after passing through a heat exchanger. On the other hand, heat pump tumble dryers recycle warm air to dry clothes at lower temperatures, offering a gentler and more energy-efficient approach. While heat pump models may take longer to dry a load compared to their condensing counterparts, they significantly reduce energy consumption and help extend the life of delicate fabrics.

How do dehumidifiers dry laundry?

A dehumidifier dries laundry by drawing in moisture from the surrounding air. This process, although slower than a tumble dryer, is gentler on fabrics, and doesn’t require any heat. Clothes dry gradually as moisture is removed from the air, often leaving fabrics in better condition. Dehumidifiers can also simultaneously help prevent mould and mildew in the home by reducing humidity levels during the drying process.

Comparing Appliances

Upfront Costs

Tumble dryers can vary widely in price, with basic condenser models starting at around £200 to £300. More advanced, energy-efficient models with features like heat pump technology can range from £500 to £1,000 or more. While tumble dryers are generally reliable, repairs for key components like motors or heating elements can also be costly, typically ranging from £80 to £200 depending on the issue and the model. Most tumble dryers come with a standard one- to two-year warranty, but extended warranties may be available for an additional fee. With regular maintenance, a good-quality tumble dryer can last anywhere from 8 to 12 years.

In contrast, dehumidifiers are generally the more affordable option upfront, with quality units priced from around £150 to £400, depending on capacity and additional features like air purification. Repairs for dehumidifiers tend to be less common but they are often more affordable than those for tumble dryers, usually ranging from £50 to £150 for issues such as fan replacements or motor servicing. Most dehumidifiers come with a one- to two-year warranty, but higher-end models might offer extended coverage. With regular dehumidifier maintenance, you can expect a unit to last between 5 and 10 years.

Which is best? Dehumidifiers generally have a lower purchase cost and simpler maintenance needs, making them the budget-friendly choice.

Speed & efficiency

Tumble dryers are undoubtedly the fastest way to dry your clothes, with most cycles lasting under an hour. For busy households with a high laundry load, the speed of a tumble dryer can be a significant advantage, especially in colder months when line drying isn’t feasible.

Penny Bellis, product marketing manager at Haier Europe, also notes, "Tumble dryers are ideal for drying bulky items like bedding and they cause less mess and disruption in the house, with clothes hanging around on clothes racks or radiators." This convenience adds to their appeal, as they can streamline the drying process.

In contrast, dehumidifiers take much longer to dry clothes, usually a few hours, depending on room conditions. They’re best suited for homes where time isn’t the primary factor, and there’s space to spread out laundry.

Which is best? For quick, efficient drying, especially in busy households, tumble dryers win hands down. They can dry a load of laundry in less than an hour.

Running costs & energy consumption

While convenient, tumble dryers generally have higher running costs and energy usage compared with dehumidifiers, making them less budget-friendly for frequent use. Even with “eco” settings, they can push up your electricity bills. But as Penny Bellis from Haier Europe points out, “Modern heat pump dryers offer reduced energy costs compared to traditional condenser and vented tumble dryers, saving you money and helping to reduce the impact on the environment.”

"Using a dehumidifier instead of a tumble dryer to dry clothes can be an excellent choice if your focus is on saving energy," explains Chris Michael, managing director of Meaco. "Dehumidifiers are significantly more energy-efficient, costing far less to operate than tumble dryers. For example, the MeacoDry Arete One 10L (available at John Lewis) operates at just 3p per hour (based on a 24.5p/kWh rate), and it typically takes around six hours to dry a load of laundry, amounting to a mere 18p per load. In contrast, a single tumble dryer cycle can cost between £1 and £2."

"For households that wash clothes daily, switching to a dehumidifier could lead to annual savings of approximately £664.30," says Chris Michael. "This calculation assumes an annual dehumidifier cost of £65.70 (0.18 x 365 days) versus a tumble dryer cost of £730 (2 x 365 days), resulting in substantial savings in both energy usage and cost."

Which is best? Dehumidifiers use less energy, making them the go-to choice for cost and eco-conscious households.

Impact on Clothes

Tumble dryers can sometimes cause wear and tear on clothes and bedding, especially fabrics like cotton and synthetics. However, modern heat pump dryers come with lower-heat settings and moisture sensors that can help minimise this impact. Penny Bellis from Haier Europe shares, “Heat pump tumble dryers evenly dry clothes – something that's not always achievable when using a clothes rack or radiator. At a lower temperatures, they can also relax the fibres in garments, so you’re left with softer towels and fewer creases."

That being said, dehumidifiers are overall much gentler on clothes, preventing issues like damage, fading, and shrinkage. “Dehumidifiers are especially ideal for delicate fabrics like wool or silk, which can struggle in a high-heat environment,” explains Chris Michael from Meaco.

Which is best? A heat pump tumble dryer is gentle enough for regular use, depending on the model. However, dehumidifiers are generally kinder to fabrics and cause less wear over time.

Space considerations

Tumble dryers usually require a bit of extra room to work efficiently. For instance, vented models will need to be positioned near a window or external wall for the hot air to be directed outside, while ventless dryers still benefit from some space around them to allow airflow. Because of this, tumble dryers are best suited to homes with a dedicated laundry or utility rooms.

In contrast, dehumidifiers offer much greater flexibility, as they tend to be compact and don’t require any special venting. They are particularly convenient for apartments or smaller spaces and can be used in almost any room. Since residential dehumidifiers are also portable, you can carry or wheel them around your home as needed.

Which is best? This depends on the size of your home. With a compact build and no need for venting, dehumidifiers are ideal for apartments or rooms with limited space. For larger family homes, a tumble dryer may be the smart choice.

Noise levels

Tumble dryers can be noisy, particularly during high-speed drying cycles, and while many modern units now offer “quiet” modes or lower decibel ratings, these settings may still produce noticeable noise, especially in an open-plan layout.

What's more, high-capacity dryers can produce a distinctive hum or vibration that carries throughout the home, potentially disrupting quieter spaces. For households sensitive to noise, you may need to locate a tumble dryer in a designated laundry room to help minimise this disruption.

Dehumidifiers, by contrast, operate at lower decibel levels and can run in the background without drawing much attention. This makes them a better fit for use in bedrooms, living rooms, or shared spaces. Even when used continuously, the sound of a dehumidifier is more akin to a light fan, making it far less intrusive than a tumble dryer.

Which is best? Dehumidifiers are quieter than tumble dryers, making them more suitable for homes where noise levels are a concern.

FAQs

What other advantages are there to a tumble dryer?

Modern heat pump tumble dryers offer more than just fast drying times. According to Penny Bellis from Haier Europe, the latest models often come with an 'allergy care' option, which helps remove allergens from fabrics. This can provide an extra level of comfort and cleanliness that air-drying or using a dehumidifier may not be able to achieve.

What other advantages are there to a dehumidifier?

As Chris Michael from Meaco points out, "Dehumidifiers are not only a cost-effective and gentler way to dry clothes, but they also offer extra benefits, such as preventing moisture-related issues like dampness and mould, and reducing condensation throughout the home."

Opting for a combined dehumidifier and air purifier setup means you’ll also enjoy cleaner air, free of dust, allergens, and other particles, adding even more value for your money.

What is the best setup for drying clothes with a dehumidifier?

If you choose to opt for a dehumidifier over a tumble dryer to do your laundry, Chris Michael, Managing Director of Meaco, has some top tips for perfecting this setup:

1. Pre-spin the laundry: Before removing clothes from the washing machine, run an extra spin cycle to eliminate as much excess water as possible.

2. Use a small, enclosed room: Hang your clothes on a drying rack (such as this steel foldable drying rack from Wayfair) in a small room, as this confines moisture to one area, making the dehumidifier more efficient. Keep all windows and doors to the room closed to prevent moisture from entering from other rooms or outdoors.

3. Properly arrange clothes: Arrange clothes on the drying rack with space between each item. Avoid overlapping items, as this can slow down the drying process.

4. Position the dehumidifier strategically: Place the dehumidifier near (but not directly under) the drying rack to ensure that water droplets don’t fall into it. If your dehumidifier has adjustable louvres, direct the airflow toward the clothes for faster drying.

5. Select the optimal mode: If your dehumidifier has a Laundry Mode, use it. Otherwise, set the dehumidifier to Continuous (“CO”) mode to maintain consistent moisture extraction.

6. Add an air circulator for faster results: For even faster drying, use an air circulator fan, like the MeacoFan Sefte Air Circulator from Amazon, to promote airflow and help dry the clothes more quickly by moving the dehumidified air evenly around the room.

Once you've chosen between a dehumidifier and a tumble dryer for your laundry needs, exploring some utility room ideas can help you design your space efficiently and make doing laundry a breeze.

As a light sleeper, I was a little sceptical that I would sleep through a dehumidifier working all night in my bedroom. But, with single glazing meaning I also have a big problem with window condensation, I'm also aware it's not healthy to sleep in an environment that is creating mould on my window frames.

While most dehumidifiers operate at a fairly low decibel level, I chose to test one that is certified by the Quiet Mark association as I hoped that would give me the lowest noise option available. In addition, the MeacoDry ABC 12L dehumidifier has a sleep setting and I was keen to see what additional benefits this offered over simply choosing a lower fan setting.

And of course, I was also keen to see just how much moisture it would remove from my room each night while I slept. Would it make a noticeable difference or would I still need to use a window vacuum to removing any remaining condensation?

Initial impressions

There's little point trying to wax lyrical about the aesthetics of dehumidifiers as ultimately they are practical products designed to serve a purpose. As they are unlikely ever to win style awards, the less unobtrusive they are the better, and the MeacoDry ABC 12L Dehumidifier answers the brief well.

It arrived clearly packaged and wasn't heavy to carry. I live in a flat which is accessed via a flight of stairs, with another to my bedroom, so given it's identified on the Meaco website as suitable for flats, it was good to see it was easily transportable if you didn't live on the ground floor.

In terms of appearance, the image on the box shows it to have a fairly standard white exterior, a simple Meaco logo on the front and a black top with clearly defined buttons and an LCD display.

The white plug and cable I found on opening the dehumidifier was also pleasing as white always feels easier to blend with an interior. Although I did question the need for a see through section on the water container on the rear of the dehumidifier. It seemed somewhat pointless given it couldn't be viewed from the front and has an auto-off function when the water tank is full. My only other initial concern was with the single in-built carrying handle. While unobtrusive, it felt unbalanced when carrying it as it naturally tilts forward.

How I used the MeacoDry ABC 12L dehumidifier

Based on the 'easy as ABC' principle, I wondered if setting up the MeacoDry ABC 12L dehumidifier would be simple. It's recommended you leave it stand for 6 hours before the first use, and if using in a bedroom, Meaco recommend not placing it at the end of the bed, just in case it gets obstructed by bedding or bed furniture.

As I didn't set it up early enough, I wasn't able to test the dehumidifier overnight on the first use. However, even though I'd missed the perfect opportunity to use it on a cold night, it did mean when I woke up my windows were covered in condensation and I could put it to immediate use.

Unpacking the item was easy and a printed instruction manual is included which is uncomplicated and easy to follow. Each part is clearly identified in the manual along with a full breakdown of how each button works. As the filter is already in place (but removable for dehumidifier maintenance and cleaning), it simply is a case of waiting 6 hours and then switching it on.

Setting humidity levels

The unit offers two ways of reducing humidity. First is a continuously on (CO)mode which means it will continue extracting moisture until you switch it off. If using the unit to dry laundry, the CO mode is recommended. The second option is to choose a desired humidity level and once you've reached that level, the unit will auto switch-off, testing the air every 30 minutes after that point and starting again if required.

As I'd not used a dehumidifier in my bedroom for some time, I opted for the higher fan setting and CO mode until the windows were cleared. Since that first use, I've also tested it during the day using the humidity setting which is simply activated by pressing the humidity button to rise in increments of 5% until you reach your chosen number.

The recommended level for normal humidity in a house is 50 - 55%rh and as I live in a listed building with single glazing, even on warmer autumn days, the humidity level is usually above this. Subsequently I've also been using the dehumidifier to keep this at an acceptable level during the day.

Activating the sleep mode

In order to access the sleep mode – the main reason I was looking to test this model – it's simply a case of switching it on and then holding down the timer button for 2 seconds which turns on the sleep function.

But what does the sleep mode do? It's designed to make the user experience more comfortable at night, which means it automatically removes all lights from the display, switches it into low fan mode and the unit won't beep if the water container fills up.

I also chose to use the CO humidity setting while asleep as I wanted to leave it on all night to see if I could both sleep through it, and wake up with dry windows. This means I've had it in sleep mode from around 11pm until 6.30am the following morning.

Testing other functions

And finally, although I tested the DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier for drying laundry, I've also used the MeacoDry ABC 12L dehumidifier with my wet washing to see how the laundry mode stacked up.

Results

Over eight weeks into testing and I'm still finding the MeacoDry ABC 12 L dehumidifier a valuable tool in my battle against bedroom window condensation. It continues to perform exactly as it says it will. Each setting works correctly, and ease of use really is as 'easy as ABC'.

Did I sleep and wake to clear windows?

As a light sleeper, waking easily if disturbed, I went into testing assuming that I'd be jumping out of bed in frustration to turn off the dehumidifier. Despite having other models in the house, I've never slept with one in my room before – mainly because I'd convinced myself I couldn't.

However, I was pleasantly surprised on both the first and all subsequent nights I've used the MeacoDry ABC 12L dehumidifier, even to the extent that I feel it's possibly improved my sleep. As I live in a town centre, the night time weekend noise can be disruptive, but the dehumidifier has almost acted like a white noise machine, helping to drown out the street noise.

When I first switched it on, I was a little alarmed as it made a relatively loud humming noise, but it quickly settled. This seems to happen every time you switch it on, but it lasts only a few seconds. Then the standard dehumidifier hum kicks in.

I'll admit to lying there for a little while on the first night, wondering if it would keep me awake, but clearly not. I've also been able to go back to sleep easily if I've woken. In terms of it passing this particular test, it certainly has.

My son has also had it in his bedroom as part of the testing and again, there have been no issues with sleep and he's woken to clear windows.

Have my condensation levels improved?

As the first round of testing involved seeing how well the MeacoDry ABC 12L dehumidifier could remove a night's worth of condensation from two large sash windows with slatted shutters, it felt like it might be a big ask for a smaller model. However, it was more than up to the job. Within a couple of hours they were clear.

On those nights that the weather forecast has indicated a drop in temperature and I've used it in sleep mode, every morning I've woken to clear windows with no condensation. One night when I forgot to switch it on, it was an entirely different case and I was back to windows running with moisture. But, it's done its duty once switched on, and even with a drop in temperature has continued to remove the condensation.

Wondering if temperature affects performance? "The size of a dehumidifier primarily determines how much water it can extract, not how well it performs in cold temperatures," says Chris Michael, managing director of Meaco. "In a cold room, a larger compressor dehumidifier will outperform a smaller one thanks to its greater power. However, if the room temperature falls below 15°C, a desiccant dehumidifier is the better option."

As my home office is also in my bedroom, as previously noted, I've also used it during the day to help improve the overall humidity levels. This has had the added benefit of making the room feel warmer too – a huge bonus with single glazing one of the main reasons for heat loss in a house and the cause of my rising energy bills.

The tank hasn't been full in the morning, although has needed emptying daily. And, as with other models tested, once it's full, removing it from the unit invariably sees a small amount splashing out onto the floor from the container. Not enough to be considered a problem, but worth noting if you're using a bedroom where carpet is the most common floor covering.

Did it work for drying laundry?

There's very little in the difference between the ability of the MeacoDry ABC 12L dehumidifier and the DeLonghi DEX212F Tascugio AiraDry model I tested when it comes to drying laundry.

However, although the water tank on the MeacoDry is larger, which means slightly less emptying, the DeLonghi dehumidifier does make the landing area where I dry my clothes warmer when the laundry setting is on, meaning it also dries the clothes a little quicker too.

Using them both to dry laundry, also led me to ask some further questions about how these two models stack up when compared at night. While I haven't tested the DeLonghi model in my room, I have been using it in my son's room at night. He's also had a lot of respiratory problems this year which is why I'm keen to eradicate the mould on window frames that has started to appear.

Meaco vs DeLonghi

When it comes to standard review criteria, the Delonghi DEX212F 12L Tasciugo AriaDry dehumidifier and the MeacoDry ABC 12L dehumidifier have a few similarities. Both extract up to 12L of extraction, operate as low as 36dB, have a laundry mode, varying fan speeds and auto switch off.

However, it's when it comes to use at night, or even during the day to reduce humidity, where the differences appear. While the MeacoDry can be put into continuous mode, the Delonghi model doesn't have this option. It also doesn't have a humidty reading display to let you choose your desired humidity level. Although the instructions explain how in low fan mode it's attempting to achieve 60% humidity, this means once that's achieved, it switches off until the level rises again.

What's happened with the DeLonghi model is that on several occasions, the dehumidifier has switched off during the night having achieved the desired level, and then not turned back on until it's close to morning. The result being that there is still condensation on the windows.

I suspect the shutters prevent the humidity level from rising too much in the bedroom and re-activating the dehumidifier, which is good in terms of the air in the bedroom being fresher than I thought, but less so regarding the long-term build up of condensation and mould.

The DeLonghi model also costs more to buy and run. Meaco states that the cost for the MeacoDry ABC 12L dehumidifier is 4p / hour based on 24.50p / kWh, while the DeLonghi model reviewed earlier this year came in at 8p / hour.

So, while there's little difference in noise and I could easily sleep with both, the fact the MeacoDry can be made to stay on all night would get my vote for bedrooms where condensation is an overnight issue.

Final verdict

Is the MeacoDry ABC 12L dehumidifier worthy of a place in our best dehumidifiers buying guide as the best dehumidifier for bedrooms? For me, it's a yes. It achieved full marks on all the tests I set of it. I slept, I woke to clear windows and it's relatively low cost to run – even when left on all night. And, a couple of months in and I still have no complaints.

Is it as whisper quiet as I thought it would be given the decibel level and Quiet Mark recognition? Possibly not, but given 40dB is the average sound of a refrigerator, 36dB is not far off this level. In hindsight, perhaps my expectations didn't take into account that while a refrigerator sound is muffled by cupboards and general kitchen noise, 36dB in bedroom with nothing blocking the sound is always going to seem a little louder at first.

Will it be a valuable addition to preventing mould in the bedroom during the winter? Of that I have no doubt and would have no hesitation in recommending it for helping it to reduce humidity in a house.

Rechargeable dehumidifiers on first impression may seem like a temptingly cheap version of their larger counterparts. Operating in a similar way to plug-in electric dehumidifiers in terms of absorbing residual moisture in the air to help remove damp and condensation, they appear to do the same job – but generally at a lower cost.

The real question is does their cost reflect their ability? Are they an alternative to the best dehumidifiers or are they simply too small to be of any use?

I take a look at this bite-size dehumidifier option to see if it has any valuable use within your home.

Are rechargeable dehumidifiers the same as portable dehumidifiers?

Given most domestic dehumidifiers can be moved around the home, the word portable can be applied to most types of dehumidifier. While those with a larger tank capacity such as the Pro Breeze 20L dehumidifier may be a little more cumbersome, they can nonetheless still be placed around the home and aren't limited to one fixed location. As long as you have a plug socket, they can be plugged in and used.

The confusion regarding rechargeable dehumidifiers can come when looking at mini dehumidifiers such as this Mini Portable Dehumidifier from Amazon . The word portable and mini could make it easy to assume it is rechargeable, or perhaps battery operated. However, make sure you clearly read the description before you buy any dehumidifiers like this as they still need mains power to work.

What mainly differentiates rechargeable dehumidifiers from other types such as desiccant vs compressor dehumidifiers comes down three factors – their tiny size, how they absorb water and where you should use them.

How do rechargeable dehumidifers work?

Rechargeable dehumidifiers such as this Pro Breeze Mini Rechargeable Dehumidifier from Amazon, work by using silica gel capsules to absorb the moisture. As the beads absorb moisture, a colour indicator changes from orange to green. This differs from most models such as the Delonghi DEX212F 12L Tasciugo AriaDry Dehumidifier which has a water tank to collect the moisture droplets.

On a rechargeable dehumidifier, there is a simple display on the front of the unit, which changes colour to signify when the capsules have absorbed their maximum capacity of water. Once full, the rechargeable dehumidifier is plugged back in for around 8-10 hours, during which time the capsules are dried and it's ready to go again. Most products claim not to need the capsules replacing at any time, and once charged should offer around 20 to 30 days of use.

However, how long before the next charge will likely depend more on when the capsules have reached their absorbency capacity. With models such as this claiming to absorb 5 floz of water, in areas with a high moisture level, they would need recharging very frequently.

Where should I use a rechargeable dehumidifier?

If you're thinking a rechargeable dehumidifier could be good to use in a bathroom as it doesn't require electricity, don't get too carried away. These are tiny units that aren't suitable for large spaces in any shape or form.

In fact, according to the experts, "there is no such thing as a battery or rechargeable dehumidifier. There are gimmicks for small cupboards that use an absorbent gel that can be reheated to dry out," confirms Chris Michael, managing director at Meaco.

They're mainly sold as best for absorbing moisture in smaller spaces such as cupboards and drawers and certainly aren't a solution for larger problems such as damp in your loft, walls or ceilings.

Where can I buy rechargeable dehumidifiers?

Rechargeable dehumidifiers available on-line

If you're looking at some of the main dehumidifier retailers in the hope of finding a rechargeable option, other than Pro Breeze, I couldn't find any of the other brands selling them – perhaps because they are closer to moisture absorbers such as the Unibond Aero 360 Moisture Absorber, than they are dehumidifiers.

Instead try Amazon or B&Q for rechargeable dehumidifiers, along with eBay and Appliances Direct. But, out of all the options, other than the shoe-attachable dehumidifier below from B&Q, they are all fairly standard units white units.

My verdict on rechargeable dehumidifiers

In much the same way as buying a budget dehumidifier vs a premium dehumidifier, it feels as if buying a rechargeable dehumidifier is likely to leave you feeling it wasn't your best purchase. Having tried a moisture absorber in the past, while it collected water, it never seemed to remove it from anywhere, so I'd say a rechargeable one certainly won't deal with your window condensation, solve any damp issues or dry your clothes. For that, it's best to stick to a mains powered version.

The main benefit of a rechargeable dehumidifier over a moisture absorber would seem to be it's more sustainable as you don't have to dispose of any items once the moisture absorber unit is wet – instead, you plug back in and use again.

That said, with two sons heavily involved in football and rugby during the winter, I admit to being tempted to try out the rechargeable dehumidifier with the shoe attachment for the wet boot aroma that invades my hallway.

Since I purchased the Dry:Soon 3-Tier Heated Airer and cover from Lakeland around seven years ago I've been an advocate - even more so after moving to properties where drying clothes outside wasn't an option. 

Come rain or shine I've been happy in the knowledge that I could dry clothes without resorting to tumble driers or radiators. And even though there have been times when washing has taken longer to dry than I hoped, I've always extolled the benefits of owning one.

However, after reading consistently positive views about the benefits of using a dehumidifier to dry clothes, I was tempted to test the claims for myself.

After researching the best model for drying laundry, I settled on the De'Longhi DEX212F 12L Tasciugo AriaDry Dehumidifier as it has received positive reviews from both purchasers and other reviewers. 

First impressions

When the DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier arrived, although the box was heavier than I expected, it was easy to unpack and contained very little unnecessary packaging. 

The smooth moulded design, sage green trim and the discreet buttons and display also meant it looked less utilitarian than other models I'd seen. As someone easily enticed by aesthetics, I was pleasantly surprised at how stylish it was up close.

Although there's no escaping the fact dehumidifiers are practical appliances designed to remove moisture from the air to help with issues such damp, I'm a firm believer of style still being important - regardless of a product's purpose. 

Specification

The DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier has an impressive specification including certification by the Allergy Standards Foundation, approving it as suitable for people with asthma and allergies.

• Dimensions (mms): 508 x 334 x 220
• Weight: 10.3kg
• Moisture removal: 12L / day
• Type: compressor
• Noise level: 36dB
• Water tank capacity: 2.1L
• Recommended room size: 55m2
• Drainage: tank or continuous
• Filters: dust, anti-allergy and active carbon filter
• Extras: dedicated laundry function

Set-up

Once removed from the box, as the DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier is a condenser dryer, you need to leave it stand for a few hours to let the refrigerant settle. Once you're ready to switch it on, there's a few simple steps to get the filters in place.

Removing the back panel to find the slots where the filters sit is a simple procedure, and requires minimal effort to click the back panel in and out of position. Once removed, the slots for the filters to sit in are easily identifiable and you do not require any technical skills to insert them.

As soon as they are in place, it's a case of clicking the panel back on and then remembering to remove and wash them regularly to ensure they continue to absorb dust and harmful air particles.

Other than this, there is no other set-up needed unless you want to use the continuous drainage function. This is also an easy task and simply involves inserting the supplied drainage tube into the grey tube shown below the filter area. Once in place, ensure the other end of the tube is positioned into a sink or drain and the collected moisture will pour away.

Using the dehumidifer

As the purpose of testing the product was to see if it dried clothes effectively, using it was as simple as plugging it in and switching it on. As the first mode is the laundry one - denoted by the clothing symbol, I didn't even have to press another button. All that was left to do was wait for it to work.

Once the water tank is full, a red light illuminates and the appliance automatically switches off. The low decibel count means the dehumidifier is fairly quiet when running, so I'd recommend you don't rely on hearing it switch off to know when the tank is full. Even though I work from my bedroom so am in close proximity to the landing, I've failed to notice the drop in noise level - it's more of a background hum than a noise I'd consider intrusive.

Once the water is emptied and the tank is back in place, the dehumidifier will automatically start working again unless you have switched it off prior to removing the tank.

Manufacturer best use instructions for drying laundry

De'Longhi experts recommend the following:

"The most effective way to dry clothes is by having the dehumidifier operating in the same room ideally with closed doors and windows, this way moisture extraction is targeted to that specific environment and not the rest of the house. 

"As the moisture is being extracted from the air, there is no specific requirement to have the product right by the clothes, and certainly no requirement for any physical contact.

"Typically the smaller the room, the quicker and more efficient the clothes drying function will be, since the moisture extraction is targeted to that specific environment."

It's also recommended to:

• Leave a free space of at least 50 cm at the front of the dehumidifier, so as not to block the air outlet
• For efficient ventilation leave a space of about 5-10 cm at the back of the appliance

How I set up my drying zone

Although I followed the De'Longhi advice in terms of placing clothes on the airer allowing for adequate spacing and minimal contact or overlapping of clothing to maximise air circulation, I was not able to adhere to the guidelines of using it in a contained room with closed doors and windows.

My normal drying location is a small landing at the top of a small set of stairs, leading to three bedrooms. Even though I can close the bedroom doors, the stairs do not have a separate door - essentially making the space far bigger. 

When it comes to frequency of usage, there are three people in my household - myself and two boys aged 18 and 11. Between casual clothing, school uniform, sportswear, towels and bedding, my washing machine is usually in use 4-5 times a week . Other than towels that I tumble dry, most items are placed on the airer.

Bedding is also draped over the landing bannister to dry, so I continued this practise while testing the dehumidifier.

Does it work?

As stated in the opening verdict, the DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier is very effective at drying laundry. But just how efficient is it compared to my heated airer?

Heated airer experience

Although I never timed exactly how long clothes took to dry on my heated airer, I do know that on average, even if I put it on in the evening and left it on overnight, sometimes thick waistbands, or items such as hoodies were still not completely dry the next morning. 

It's not the most scientific of measurements, but how I tended to view its efficiency. Added to this was the fact that without the cover, it easily took twice as long to dry the items. 

Unless the items were lightweight or the room temperature itself was higher, I could never rely on washing being dry in a few hours. Emergency requests for something to be dry in time were usually dealt with by a blast in the tumble drier or a stint on a radiator. 

And, as I was usually replacing one load of dry washing with another wet load, there were times when I felt it was constantly switched on - especially in the winter.

Prior to using the dehumidifier, as I was conscious I was expecting it to operate effectively in a larger, more open space than recommended, I was assuming results would be much the same. And if I'm honest, I thought it would take even longer.

DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier experience

But it's always good to be proved wrong.

After a month of testing, I've never once had to leave it on overnight. Most items are iron-dry within a few hours - the only exception being the occasional hood, cuff or waistband of my son's thick hoodies. But even with a little repositioning on the airer they are soon dry enough to put into a cupboard.

Added to that, clothes feel softer, have never smelt damp - something which I experienced with the heated airer - and as the dehumidifier pushes out warm air in the laundry mode, the landing itself is also feeling warmer and fresher. 

Given that there are no windows, I'm also feeling less worried about the extra moisture the wet clothes are adding to the space as I know the dehumidifier will be dealing with it.

Even bedding which has been draped on the bannister and isn't directly next to the dehumidifier is drying in the same time frame. 

Have I put less on the airer then when it was heated? Potentially a few items less, but as time has gone on and it's worked so well, I've added more. It also has an auto switch-off function when the tank is full, so even if I forget to turn it off, it will stop operating. Something the heated airer didn't do as there was no timer on the one I have.

And with regards to emptying water, I've found myself doing this once a day at the most if I've managed to squeeze in two loads of laundry. Usually it seems to be around every other day. 

So whilst the water tank may be small if you are using it 24/7 to dry a room or deal with a damp problem, for laundry it hasn't been too arduous a task.

Costs to run

My heated airer is sold under the premise of costing 9p per hour to run, whereas the  DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier costs around 8p per hour. A negligible difference per hour, but one that will mount up over time with quicker laundry drying times.

I've not yet noticed a difference in my electricity bills and don't really expect to while it's still relatively cool in terms of ambient temperature. Once the warmer months arrive, and the daily temperature is consistently higher (unlike now where it only peaks when the central heating is on) I would hope my laundry dries even faster with the dehumidifier.

Final verdict

I wish the display showed more

Even though I wasn't using the DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier to assist with mould removal, I was a little disappointed to see it didn't have a display with a humidity reading. 

Knowing how much wet washing in a room increases the humidity would have been beneficial and also seemed slightly unusual given the larger 14L and 16L versions do have an LED display that shows this number. 

As I live in a listed building with single glazing, I have another dehumidifier in my son's bedroom to help deal with window condensation . This shows the humidity level and I would have been interested to see if they read the same results.

Without a reading, I feel it would also make it more difficult to use in a house with a moisture problem. When it comes to what is normal humidity in a house, the aim is to reach somewhere around the 40-50% mark. The DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier has three options denoted on the front by one to three water droplets which equate to 40, 50 and 60% humidity.

Common sense would suggest that if you're unsure, aim for the middle setting. It will auto switch-off once it's reached the required level, so if you find this isn't sufficient, you can easily change it. Or, consider where you've placed the dehumidifier. Kitchens and bathrooms will naturally have higher moisture levels.

It's also quite heavy to carry, but if you're using it to dry laundry the chances are it will stay in one location so I don't feel this is too much of a negative. Likewise the fact the water tank is relatively small compared to the extraction rate could be off-putting if you have to walk a distance each time to empty it.

But I would thoroughly recommend buying one

If there's a fan club for using a dehumidifier to dry laundry then sign me up as despite my initial reservations, I'm a fully-fledged convert. The DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier is cheaper than the cost of running a tumble dryer and for an appliance, even visually errs on the side of stylish. 

I love the speed at which my laundry now dries and the fact it's softer and easier to iron. It's also relatively small and not something I'd be trying to hide in a cupboard when guests visited. I think my 'heated airer' has well and truly been demoted to the position of 'airer' for the forseable future.

I'm also looking forward to testing its ability to remove the condensation from the windows in my bedroom in the winter.....if I ever give it a rest from drying clothes.

Aldi has started selling a budget dehumidifier for shoppers at their stores.

The new Aldi dehumidifier is being sold as part of the supermarket's "SpecialBuys" range, unique deals that go on sale at its stores and online every Sunday and Thursday.

And this latest addition is a curious one, coming to the supermarket's middle aisle as the increase in demand for the best dehumidifiers causes a supply shortage in the appliance across Britain. 

Here we take a look at the new Aldi dehumidifier's credentials, its price (we're impressed!) and why you need to be quick if you want to get your hands on one.

What is the new Aldi dehumidifier?

Aldi's dehumidifier is the Ambiano 12l Midi Dehumidifier, which is a compressor dehumidifier best suited to homes where the temperature isn't often below 15°C.

Ambiano is the brand Aldi uses for many of its popular middle aisle products, including its air fryer, coffee capsule machine, soup maker, pressure cooker and bread maker.

Aldi says in its description for the dehumidifier: "Dehumidifiers are great for removing damp from your home. They can also be great for helping clothes dry quicker when placed by your airer."

How much does the Aldi dehumidifier cost?

Aldi really has gone into battle over its price point, with its Ambiano 12l Midi Dehumidifier currently on sale for the bargain price of £89.99. 

Similar products with this capacity typically retail for upwards of £100, although it is possible to buy 12L dehumidifiers for as low as £91 on Amazon.

It is not the first time Aldi has offered up a dehumidifier in its middle aisle either, but its previous Easy Home model was a much larger 20L with a higher price tag.

Comes with an adjustable humidity gauge

From clearing window condensation to reducing issues with damp in your home, when you look at how do dehumidifiers work, they are essentially appliances that help remove water from the air. 

And while the more premium units tend to have more functionality, the Aldi dehumidifier offers a surprising range of features - despite its bargain price. 

For starters it has an adjustable humidity gauge to set a normal humidity in a house target level  (typically around the 50-55%rh range) as well as adjustable fan speeds. 

The unit, which is only 200 watts, also comes with:

• 24 hours programmable timer
• Adjustable humidity level
• Child-lock function
• Touch screen control panel
• Overflow protection
• Dust filter
• 3 colour changing lights
• Practical recessed grips
• 4 wheels for ease of moving
• Low noise level

But no laundry mode for drying clothing

If you are purchasing a dehumidifier to dry clothing quickly, it is worth knowing that the Aldi dehumidifier doesn't have a specific laundry mode. These modes on dehumidifiers typically are a high power setting that allows the unit to extract more moisture from the air, perfect in a small room with lots of wet clothing in it.

That said, the Aldi dehumidifier will still extract moisture from the air so not having a specific laundry mode doesn't mean it won't do the job of drying clothing - it just means it might not be quite as effective or as fast.

Aldi’s dehumidifier has a decent size tank

As with most appliances that deal with water, the volume of water the unit can handle usually defines how useful it is. 

The Aldi dehumidifier doesn't disappoint, offering a 12L tank capacity. With this capacity, as well as its ability to automatically shut off when the tank is full, the dehumidifier should in theory deal with a variety of domestic needs.

But it is already selling out fast

This appliance appears to be fairly decent value and that coupled with the huge demand for dehumidifiers, perhaps explains why it is already selling out in stores across Britain.

An Adi spokesperson tells Homebuilding & Renovating there are only 100 units left in store across the UK, with the appliance already sold out in Ireland.

Is the Aldi dehumidifier worth buying?

Without testing it in person (we have struggled to get our hands on one too), it’s impossible to give a proper verdict on whether to choose this budget dehumidifier vs a premium dehumidifier. But Homebuilding & Renovating's Amy Willis, who has reviewed several dehumidifiers in the past, says the Aldi dehumidifier is likely to be ideal to tackle minor damp issues and help dry clothing in a warm house if you don't have a tumble dryer.

"It has a decent capacity at 12L as well as some handy features like the timer, overflow protection and adjustable fan speed for those worried about energy costs. While it might not be the most attractive of dehumidifiers, at £89.99 it is definitely worth a punt," she said. "That said, those with serious damp and mould problems might be better off investing in a more premium model instead."

It is also worth pointing out that the Aldi dehumidifier comes with a three year warranty so there is reassurance that if the product does require repair or replacement, you have protection in place. But, it is also important to make sure you carry out dehumidifier maintenance on the unit too.

It isn't the only budget option out there

If you don't get the chance to snap up the Aldi dehumidifier there are a few more budget options out there, for a similar price point.

Homebuilding & Renovating's Gabriella Dyson tested the budget range Hysure 700ml Automatic Dehumidifier, which cost her only £50, and found it effective enough to help with damp on her skirting boards. Although, she highlighted that a larger unit might have been better in a larger room.

"This dehumidifier is perfect if you're trying to achieve normal humidity in a house or you only have a small room to cover," she explained. "However, if you have significant issues with condensation then you should invest in a more serious piece of kit. I recently reviewed a much larger and more expensive dehumidifier - the ProBreeze 20L Premium Dehumidifier- and I would recommend purchasing this model over the Hysure if you have a bigger home."

Other dehumidifier options include this EcoAir DD2 Simple Desiccant Dehumidifier for those with colder homes (this one warms the air too) as well as the Meaco 20L Low Energy Dehumidifier.

Dehumidifier companies reported that there was a shortage of dehumidifiers over Christmas and New Year, which is expected to continue in 2024.

The rise in sales of the best dehumidifiers has been put down to homeowners trying to lower their energy bills over the cold winter period with the energy-efficient product proving useful for drying clothes relatively cheaply as well as solving damp and mould issues caused by keeping the heating off in cold, damp weather.

Dehumidifier suppliers are now preparing for how they can meet the rising demand this year, although they predict meeting the unprecedented rise in demand could mean the shortage continues into 2024.

Dehumidifier shortage causes waiting list of over 20,000

One dehumidifier supplier claims they had a waiting list of over 20,000 people over the Christmas period wanting a dehumidifier, which they could not provide.

Chris Michael, managing director of dehumidifier supplier Meaco, stated: "Demand has been bonkers. We can't keep up with it.

“Our sales grew from 150,000 dehumidifiers in 2022 to 320,000 dehumidifiers in 2023, so a massive growth spurt. The entire UK market was smaller than that when we started to sell dehumidifiers!

"We did have shortages throughout the autumn, and we could have sold around another 50,000+ units, but the increase of 170,000 units is something that we are proud of."

The Household Dehumidifiers market is expected to grow in the next few years, with the the global market size predicted to reach multimillion figures by 2030, with an unexpected annual growth rate between 2023 and 2030 compared to 2021, according to the global Household Dehumidifiers Market report.

Why was there a shortage?

It is no coincidence the dehumidifier shortage occurred during the coldest period year with an increasing number of homeowners using dehumidifiers to heat their homes and save on energy bills.

As dehumidifiers proved to be effective at removing unwanted water from the air homeowners began to question whether "Does a dehumidifier heat a room?" with the answer proving to be "Yes" with desiccant dehumidifiers being used by many to release heat into homes.

Some homeowners have found that dehumidifiers dry clothes more efficiently than tumble dryers meaning they can help homeowners save money on their energy bills, which is vital with the country seeing energy prices rises.

What are companies doing to counteract shortage?

In hindsight, Chris Michael says the company could have sold 50,000 more units last year, but is now preparing to meet the growing demand in 2024.

He added: "We are looking for further growth in 2024 and have already started to plan production throughout the summer to meet that anticipated demand and hopefully be in stock, for all lines, in 2024.”

Michael says Meaco are planning to supply 100,000 more units than usual to meet demand, meaning, 280,000 in total will be supplied, but claims this may still not be enough.

The EcoAir DD2 simple desiccant dehumidifier is designed for spaces where the temperature might be lower than typical room temperature. For instance in a colder house, or in a garage or conservatory where damp could potentially thrive.

Even the best dehumidifiers that work on a compressor system are unlikely to be as effective in these spaces, while desiccant dehumidifiers are specifically designed to be able to tackle the cold without a change to its efficiency. Desiccant dehumidifiers also gently expel hot air to warm the space, while compressor dehumidifiers do not.

Here we review the EcoAir DD2 simple desiccant dehumidifier, which is available to buy on Amazon, to find out how it performed to stop mould, condensation and damp.

Is the EcoAir DD2 Simple desiccant dehumidifier easy to setup and use?

When the dehumidifier first arrived, unboxing it was simple. You could easily lift it out using the two handholes on either side towards the back of the unit. It was very lightweight at 6.7kg, making removing it from the box straight-forward.

My initial impression of the EcoAir DD2 simple desiccant dehumidifier was that it is a very slick-looking unit. It is a sensible height at just over half a metre along with being fairly slimline with a depth of only 25.3cm. This made it easy to tuck away when not in use. The unit also came with a one-metre long plastic hose for continuous drainage, a bonus I was looking forward to trying out. 

Next was connecting the machine to a power outlet and figuring out how it worked. Initially the three digital options on the top of the unit took some thinking about but the instruction manual made everything very easy to understand. The left button toggled between its economy and turbo modes, the centre button set the desired humidity level, and the third powered up the unit. 

If I was being picky, it might have been nice to see the exact humidity level displayed in numbers on the unit (the geek in me likes watching to see the humidity drop) but this really was a minor point. It's worth noting too that on the humidity dial more droplets indicates more water extraction rather than higher humidity.

But all in all, I quickly had the EcoAir DD2 simple desiccant dehumidifier powered up and working without much effort. It was easy to move around too.

How did I test the EcoAir DD2?

A desiccant dehumidifier works differently to a compressor dehumidifier in terms of how a dehumidifier works and for this reason we tailored the testing process to settings where these types of dehumidifier are best suited. In my home, these included:

1) In my cold kitchen/diner area: Circa 12°C/14°C with a damp wall and single-glazed and draughty sash windows.

2) In my unheated garage: This is currently storing my second-hand utility room units that currently have mould growing on them.

3) In a large (and old) white van that I have on my driveway that is storing other bits of wood and offcuts that may or may not come in handy for future building projects. The van suffers from condensation on the internal roof due to poor airflow and cold metal walls.

Did the EcoAir DD2 work well inside?

I was impressive at how well the desiccant dehumidifier handled all three places where I tested it but inside was perhaps the biggest test, given that compressor dehumidifiers are usually the go-to option for internal domestic spaces.

But it turns out that when your room temperature is regularly below 15°C, a desiccant dehumidifier can be a better option. The guys over at Meaco suggest: "As a guide, don’t use a 10 or 12 litre compressor machine below 15°C and only use the larger 20 and 25 litre machines down to 10°C."

This is because compressor dehumidifiers can become less effective when operating below 15°C as they work by passing air over a cold coil to condense the water and collect it. When temperatures drop, the cold coil is no longer cold enough compared to the surrounding air to condense the water.

A desiccant dehumidifier meanwhile doesn't have the same problem as it works instead by drawing in air over a filter containing a material called "zeolite". Desiccant dehumidifiers also warm the air too, which is an added bonus in notoriously cold spaces. You can read more on this in our piece: desiccant vs compressor dehumidifier.

Inside my cold kitchen/diner

My kitchen/diner area is a great example of a room inside a house that is actually a little on the cold side for a compressor dehumidifier. The room's temperature is around 12°C to 14°C in winter (sometimes lower if I don't put the heating on), making it the perfect testing ground for the EcoAir DD2 simple desiccant dehumidifier.

Plugging the EcoAir DD2 desiccant dehumidifier in for the first time inside, the handbook warns users not to worry about any peculiar smells wafting from the unit. I didn't notice this until getting right up close to the air outlet and can only describe it as a subtle plasticky waft. This is the air passing over the Zeolite and apparently is not at all hazardous. I can't say it bothered me but it was of note and is the case for all desiccant dehumidifiers not just this model. This smell disappeared within a few hours of use. I also enjoyed walking past the dehumidifier as it gently expelled hot air into the otherwise cold room.

The EcoAir DD2 simple desiccant dehumidifier is able to operate between temperatures of 1°C up to 40°C, an impressive temperature range, so why wouldn't you ideally use this in rooms above 15°C? Essentially, you can but it comes down to running cost and when the room temperature is suitable for a compressor dehumidifier, these can be cheaper to run at warmer room temperatures.

Was it effective in colder temperatures?

In terms of testing the EcoAir DD2 in external domestic spaces, I was impressed by its dehumidifying ability despite temperatures dropping close to freezing point.

Inside the cold garage

While I didn't risk testing to the dehumidifier's exact low temperature threshold of 1°C (there's no automatic switch-off if temperature go below it), I tested the dehumidifier when temperatures were due to dip to a minimum of 4°C overnight and found the unit impressively effective. 

Humidity levels in the garage started at around 70%RH, according to the dehumidifier's humidity gauge, and ended up at around 60%RH after running it for 24 hours.

My garage has no insulation in the walls or roof and a large gap under the old-fashioned 80s metal garage door. Therefore it was good to see that despite this there was still a substantial drop in the humidity level. I was able to wipe the mould off my utility room units and be confident it wouldn't return with the humidity level closer to the 40-60%RH range for a normal humidity level in a house.

I also have an open drain in my garage, courtesy of the old owner of the house,  which came in super handy for using the continuous water drainage functionality of the machine. I found this function particularly useful as it meant I could leave the dehumidifier to do its thing without constantly checking if the 3 litre water tank needed emptying. 

The dehumidifier's automatic shutoff when it reached the desired humidity setting (and automatic restart) also added to this feeling of being able to leave the machine to get on with the job.

Inside the cold van with condensation

Inside the van, the dehumidifier was even more effective, I suspect because it was more of a sealed environment with less airflow. The key challenge here was whether or not the desiccant dehumidifier managed to eliminate the "sweating" and get rid of the condensation from the inside of the roof.

Within 24 hours I can report that it definitely passed the test, with a starting humidity of around 70%RH down to around 55-60%RH and not a drop of condensation in sight. I wasn't able to attach the continuous hose as I couldn't find a suitable gap, but the 3 litre tank was enough to last the night, ready for emptying in the morning (there's a handle on the tank too for easy emptying). It is also worth pointing out that the dehumidifier was easy to move around due to being lightweight and not too cumbersome in its shape.

What was note-worthy is that rigging up a dehumidifier inside a van is potentially a challenge. I was only able to do this as I have outside plug sockets on my driveway and a van that has been internally wired with sockets as well as having an external waterproof ABB connector for power. Similar might be true for those that want to use the EcoAir DD2 in a caravan or other vehicle with power points inside.

How often did the dehumidifier need emptying?

With the continuous drainage pipe attached, the EcoAir DD2 simple dehumidifier never needs emptying, which is an incredibly useful feature as long as you have a  drain for the water from the pipe to flow in to. The pipe, which comes with the unit unlike some other brands of dehumidifier, is one-metre long which was sufficient to reach the drain in my garage. However, it might be worth having an extension lead on stand-by if your power hookup isn't close to a drain.

It is worth noting that the continuous drainage pipe is gravity-fed and won't work with a sink unless you can lift the dehumidifier up to sink level. It does however revert back to tank drainage if you encounter this problem.

Fitting the continuous drainage tube was straight-forward but a little fiddly. The hole for it at the back of the unit was easy to access by popping out the plastic with a screwdriver, but pushing the plastic hose into the outlet took some reshaping of the hose so it was perfectly round and lining up. 

And, in case you were wondering, if you don't want to use the continuous drainage functionality, the machine easily switches back to using the tank if you remove the hose. It doesn't matter if you popped out the plastic bit or not.

How much does the EcoAir DD2 cost to run?

Typically, desiccant dehumidifiers are more expensive to run than compressor dehumidifiers due to being higher wattage. However, the EcoAir DD2 simple desiccant dehumidifier was built with energy saving in mind with a very low 260 wattage on its lowest setting, up to 570 watts on its highest setting.

At the lowest wattage, this means the EcoAir costs 7.1p per kWh to run with current energy prices of 27.3p.

The calculation is: 0.260kWh x 27.35p = 7.1p per hour. I ran the dehumidifier for an average 8 hours per day, meaning I spent roughly 56.8p per day or £1.70 for when I ran it for an entire 24 hours. This of course doesn't take into account when the dehumidifier automatically shuts down after reaching the desired humidity level.

To put this into perspective, the popular Meaco low energy dehumidifier - a compressor dehumidifier – is 219 watts to run (6p per hour) on its lowest setting – so the EcoAir was actually very comparable, despite being a desiccant dehumidifier. 

Does it have a laundry mode?

I was pleased to find that the EcoAir DD2 simple has a very powerful laundry mode, which is essentially a super-high setting (or rather a super low humidity setting) to extract extra moisture from the air.

This was easily selected by using the dial's maximum moisture extraction setting.

Is the EcoAir DD2 noisy?

I was impressed with how quiet this particular dehumidifier was. At only 37-46 decibels it beats many of the best dehumidifiers on the market at the moment, which was beneficial so I could keep it running in the background during online meetings for work.

Are there any additional features?

Yes, there are a couple of additional features with this dehumidifier that were useful. The EcoAir DD2 comes with an anti-tilt feature for safety, which is handy when moving it about into places like garages where you might be moving other items around and knock the machine unintentionally.

The EcoAir DD2 also has an antibacterial filter that was easy to clean when looking to do your regular dehumidifier maintenance (important to do this with all dehumidifiers).

Do I recommend the EcoAir DD2?

If you are looking for a desiccant dehumidifier to eliminate damp, mould or condensation (or all three) in colder spaces I would definitely recommend spending the money and buying the EcoAir DD2 Simple dehumidifier. 

It can  run at both energy efficient levels as well as having more powerful settings to tackle intensive humidity levels where needed. While it has only a small 3-litre tank this was ample for a 24-period with the extra option of continuous drainage to be able to leave the dehumidifier for longer periods when set-up in a space like a van, garage or caravan that you might not want to check regularly.

The unit is also lightweight and easily manoeuvrable, which I found very useful when testing the product in different areas. I can imagine this would come in useful to remove the likelihood of needing to buy more than one unit for different places in the home.

All-in-all the EcoAir DD2 was an easy to use, good all-round machine. A bit more pricey, perhaps, but worth it.

What's the difference between a desiccant and a compressor dehumidifier? If you're in the market for a new machine, you might be wondering which model is best for your home. It's a good thing you asked, because using the wrong one could damage the unit, overdry your room, and increase your energy costs.

The best dehumidifiers remove condensation and dampness from your home, helping to prevent and reduce problems like mould, which can cause serious health issues over time. While both desiccant and compressor models achieve the same result, they work in different ways, and they're not suitable for the same environment.

Below, the experts explain the differences between these two types of dehumidifiers, so you can determine which is best for your home and lifestyle. You'll also learn about the pros and cons of each, and how they compare head-to-head on factors like noise levels, size, and energy efficiency.

Desiccant vs compressor dehumidifier: Quick comparison

Our top picks

Should I get a desiccant or compressor dehumidifier?

This ultimately depends on where you want to place it. If you're looking to reduce damp in a cold environment – such as a basement, unheated garage, or boat – then a desiccant dehumidifier is the best option. For warmer rooms, like kitchens, bedrooms, and utility rooms, choose a compressor model instead.

You might think that you can use these interchangeably, but placing a compressor dehumidifier in a cold room can cause the coils to freeze, stop water collection, or even make the device shut off to prevent damage.

Desiccant models also have the added bonus of producing a small amount of heat, which is another reason why they're best for colder rooms in your home.

Desiccant vs compressor dehumidifier: Pros and cons

Dehumidifiers can be expensive, so it's worth weighing up the pros and cons before you decide to make the investment. We asked Chris Michael, founder of Meaco, to share his thoughts:

Pros of desiccant dehumidifiers

1. Perform well in cold rooms: They’re a good choice for unheated spaces, such as garages and basements.
2. Lighter and quieter: Desiccant models tend to be easier to move from one room to another, and for those concerned about the noise of dehumidifiers, you'll be pleased to hear that this type isn't too loud.
3. Produces heat: The warmer air output can help to heat the room.
4. Best for laundry: Cheaper than a tumble dryer and quicker than compressors, desiccant dehumidifiers are excellent at drying wet clothes.

Cons of desiccant dehumidifiers

1. Higher energy consumption: They use a lot more energy since they heat the air.
2. Less cost-effective for year-round use in mild or warm homes: They have higher running costs compared to compressors.

Pros of compressor dehumidifiers

1. Energy-efficient: In warm or heated homes (above 15 °C), compressor dehumidifiers are the most energy-efficient option.
2. Some models offer air purification: Particularly useful for allergy sufferers, some compressors offer a two-in-one design that filters unwanted air particles while reducing humidity.

Cons of compressor dehumidifiers

1. Less effective in cold rooms: Performance drops when temperatures fall below 15 °C, and the unit may stop working entirely around 5 °C due to freezing coils.
2. Heavier and noisier than desiccant models: It’s bad news if you plan to move the device between different rooms or sleep with it.

Which is better: compressor or desiccant dehumidifier?

You might be wondering whether a desiccant or compressor dehumidifier is better, but Laura Bradbury, Head of eCommerce at Vonhaus, says there's no "one-size-fits-all" as both have their place in the home.

"Compressor dehumidifiers are great for warm, centrally heated spaces and tend to be a little more energy-efficient. Desiccant models work better in cooler areas like garages, conservatories, or utility rooms, and they also release a gentle warmth while running.”

However, compressor models tend to be the most popular choice for UK homes, according to Chris Michael.

Laura Bradbury concludes, "Whichever type you choose, a good quality dehumidifier should last for years with regular care."

So, once you've decided between a desiccant or compressor model, it's worth learning how to carry out proper dehumidifier maintenance to keep it going for as long as possible. Or, if you want a full breakdown of how dehumidifiers work, you can read our expert's guide.

While proper ventilation is the key to tackling issues like damp and mould in our homes; air purifiers and dehumidifiers play a crucial role in enhancing the overall quality of the air we breathe every day. 

But while there is some crossover between air purifiers and dehumidifiers, the main functions of these appliances vary. 

Below, we take a closer look at the differences between the two, and examine why you may require a combination of both an air purifier and a dehumidifier to improve your home's air quality.

Air purifiers vs dehumidifiers – what's the difference?

At first glance, air purifiers and dehumidifiers might seem to fulfil similar roles in improving indoor air quality, but they serve different functions.

Air purifiers are designed to filter out airborne pollutants, allergens and odours, ensuring the air you breathe is cleaner. 

Dehumidifiers, in contrast, reduce excessive moisture in the air, which can lead to problems like damp, mould and mildew. 

Why would you use an air purifier?

Air purifiers operate by trapping a variety of airborne particles. These include common irritants like dust and pollen, making them ideal for homes in urban settings or for individuals suffering from allergies and asthma.

An air purifier might be the ideal solution if you or your home are troubled by the following:

• Persistent allergic reactions.
• Smoking fumes.
• Bad odours. 
• Pet dander.
• General concerns regarding indoor air pollutants.

Certain air purifiers are designed to trap volatile organic compounds (VOCs) and other potentially harmful chemicals that may be present in household cleaning products, paints or building materials. Other models – equipped with UV-C light – claim to kill airborne germs and bacteria, reducing the spread of illnesses in the home. 

The Honeywell Premium True HEPA Air Purifier, from Appliances Direct, is a popular model of air purifier. It contains an activated carbon filter to reduce odours in the home, as well as an ioniser to remove mould spores from the air. 

It's worth noting that an air purifier is not designed to treat damp. Dampness is related to poor home ventilation and the level of moisture in the air, which an air purifier does not affect.

Why would you use a dehumidifier?

Conversely, the best dehumidifier will not only help treat damp in your home, it can also solve condensation and even dry your laundry. Rather than trapping air particles, a dehumidifier works by extracting the moisture from the air.

For mould issues, a dehumidifier – like the Probreeze 20L Premium Dehumidifier – is generally more effective than an air purifier. Mould thrives in moist environments, so reducing excessive humidity levels in your home with a dehumidifier can help prevent mould growth. While an air purifier can filter mould spores from the air, it won't address the root cause of mould. 

When would you need both appliances?

In certain situations, your home environment might benefit from the combined use of both an air purifier and a dehumidifier. If, for example, you have high humidity levels in your house, as well as pets who shed their fur everywhere, you may see the benefit to using both. 

Using an air purifier and a dehumidifier together can improve the overall air quality in your home. The dehumidifier reduces moisture and prevents mould, while the air purifier cleans the air of particulates and allergens. The Meaco low energy dehumidifier and air purifier is a good example of a unit that does both.

FAQ

When it comes to tackling humidity in your home, dehumidifiers are invaluable. These helpful appliances not only combat condensation, they can also reduce damp and mould, help you dry your laundry and cut your energy bills. 

But what do you do if you suspect your dehumidifier is broken or on the brink? Is it possible to fix a broken dehumidifier or is your handy moisture extractor doomed for the landfill? 

We asked two leading manufacturers – ProBreeze and Meaco – how you can tell if your unit is breaking and what you can do to fix a broken dehumidifier. 

The signs your dehumidifier might be broken

"If your dehumidifier is broken it will stop collecting water or start to make unusual noises," says Chris Michael, Director at Meaco (U.K.) Limited. "Some more sophisticated machines like the Meaco models will provide an error code to help tell you, or the manufacturer what the fault is". 

When in doubt, these are the signs that your dehumidifier is broken or will soon need fixing: 

1. Your dehumidifier is no longer collecting water 

The most obvious sign that a dehumidifier is broken is that it is no longer collecting water. If the tank remains dry despite extended use in a humid environment, it's clear that something is amiss. 

2. It's making unusual sounds 

Noises such as rattling, buzzing or grinding are not part of a dehumidifier's standard operation. These sounds point to an operational fault. 

3. There's an odd smell 

A musty or burning smell emanating from your dehumidifier is cause for concern, as these potentially indicate overheating or mould growth within your unit. 

"Thankfully, most faults are fixable," says Chris Michael. "The first thing you should do is consult your user manual or ask the manufacturer if they can help."

Troubleshooting your appliance

If you suspect your dehumidifier is broken it's a good idea to troubleshoot the most common causes of malfunction before seeking professional help. Regular dehumidifier maintenance is key to keeping your appliance in good working order.

Here's what you should do in response to common faults: 

Can you fix a broken dehumidifier?

If you've tried all of the above troubleshooting techniques and you still suspect your dehumidifier is broken it's time to get in touch with the manufacturer. They will be able to recommend the best course of action to fix the product or replace the unit for you if it's still within warranty. 

You'll find plenty of DIY videos online that will outline how dehumidifiers work and provide advice on ways to fix a broken unit. However, you should be careful not to tamper too much with the mechanisms of your dehumidifier unless you know what you are doing, as this can affect your warranty and prevent you from receiving a replacement or a refund in the event that it is broken beyond repair. 

"The manufacturer should always be your first port of call," concludes Chris Michaels. "But as a last resort, take your broken dehumidifier to your local council recycling facility. They will be able to dispose of or recycle your appliance in a responsible way".

With the right dehumidifier maintenance, your purchase can be expected to last you longer and perform better for you — but do you know which jobs you should be focussing on to keep it in good working order?

All of the best dehumidifiers remove excess moisture in the air within the space where they are located. The most common type of dehumidifiers are compressors. 

"This type of dehumidifier draws in the air, over a filter and has a cold-coils system, like a fridge," says Chris Michael managing director at Meaco. "They have two sets of coils, the first cools to create the condensation, which is collected into the water tank, the second warms the dry air back to just above room temperature. This helps to create the dry air needed to combat condensation, mould and damp problems."

In this handy guide, we reveal what the experts recommend when it comes to maintenance and pass on their top tips for keeping your dehumidifier in peak condition.

Essential dehumidifier maintenance tips to follow

Getting to know how dehumidifiers work is relatively straightforward, but some regular maintenance is required for them to continue to work at maximum efficiency. 

As well as cleaning the filter, other jobs to put on your to-do list from time to time include keeping the water tank clean and dusting off the air grilles when they look like they need it. 

"The water tank will benefit from a wipe now and again, but once a season should be fine for that," says Chris. "For the air grilles, a feather duster will be fine for this when you see any dust build up."

1. Clean the dehumidifier filter

According to Chris Michael, the main focus of your maintenance should be on the filter within the dehumidifier. 

The filter is one of the most important things to take care of in order to keep it running at its best. Regular cleaning should also mean that replacing it will not be required. 

"For dehumidifiers that don’t offer HEPA filtration, the air filter is pivotal in extracting dust and other large particles from the air in your home," says Chris. "If the air filter is not properly cleaned it can result in the dehumidifier to stop functioning. The air filter is crucial in protecting the parts inside the dehumidifier and cleaning the dry air in the room. If the air filter is dirty or covered in dust, the dehumidifier will not do its job as the air will not be able to pass through.

"We recommend cleaning the filter every two weeks," suggests Chris. "To clean the air filter, you can carefully vacuum it, or if the suction of the vacuum cleaner is too strong, you can also use a damp cloth and warm soapy water, to gently wipe the dirt away. 

"The water should be no hotter than 40°C. Once all the dust has been rinsed off, simply dry the dehumidifier filter with a tea towel before placing it back in the dehumidifier. If the air filter is kept clean it should not need replacing, except for reasons of wear and tear."

2. Replace the HEPA filter regularly

Some dehumidifiers, such as the Meaco 20L Low Energy dehumidifier we've reviewed, come with HEPA filters. A HEPA air filter is made up of thousands of very fine fibres compressed into a mat which can grab both microscopic particles as well as bigger ones.

"In order to maintain fresher, cleaner air in the home we recommend the HEPA filter is replaced roughly every three months," says Chris. "The HEPA filter provides enhanced air cleaning capabilities, turning your dehumidifier into a combined dehumidifier and air purifier. The HEPA is used in addition to the dust filter that comes as standard in dehumidifiers, so that you can get two stages of filtration. The old HEPA filter should be disposed of."

3. Store your dehumidifier correctly

You probably won't need your dehumidifier to be up and running all year round — but what is the best way of ensuring it is stored safely and ready for when the time does come around to get it out again?

"If you are going to stop using your dehumidifier for any length of time, then we would recommend running it on AP mode (air purification mode) for several hours first," says Chris. "This mode runs the machine on fan only and this will help to dry out the cooling coils before putting it into storage. This will reduce the chances of any mould build up inside the machine while it is not being used. AP mode, incidentally, is available on the Meaco Arete and Low Energy ranges."

4. Choose the best location for it

While dehumidifier maintenance is not too time consuming or difficult to carry out, using your machine properly and locating it wisely can help with the performance and overall running of your dehumidifier. 

"You should place your dehumidifier where it is most needed, but remember that a compressor dehumidifier should never be used in a space smaller than 4m² and electrical appliances should not be used in the bathroom for safety reasons," advises Chris. 

While keeping your dehumidifier in good running order should not be too time consuming, if you want it to last as long as possible, it is wise to keep your eye on its upkeep. 

Concentrate any maintenance efforts on the filter and ensure HEPA filters are changed regularly. 

Other than cleaning filters and keeping air grilles free of dust, these handy machines are a fuss-free way of keeping moisture levels under control, plus dehumidifiers can help to dry clothes too, making them a practical buy for any home. 

Having one of the best dehumidifiers can offer a reliable solution to removing moisture from the air. From banishing damp, mould and condensation to helping to dry washing in the colder, wetter months, a dehumidifier is an essential appliance to have handy around the home. It’s one you’ll find helpful to have access to when drying out fresh plaster during a renovation, too (trust us – we’ve been there!)

Its versatility is unrivalled, and yet when it comes to buying a dehumidifier, the technical specifications can be a lot to get your head around. Much like the time when you’re looking at the best portable air conditioners; anything that manages the indoor air quality can be heavy talk.

As a team, we’ve spent months testing some of the latest and greatest dehumidifiers, evaluating factors like moisture removal, noise levels and running costs. With this information, we’ve created a list of the best eight dehumidifiers, with Meaco 20L Dehumidifier coming out on top.

Best dehumidifier overall

The Meaco 20L Low Energy Dehumidifier/Air Purifier is designed to help control humidity levels in a house, reducing or even eliminating window condensation and, subsequently, minimising the risk of damp.

On test, we also found that it offers further benefits. It can help to dry laundry quicker and, thanks to its HEPA filter, can also purify the air – ideal for those with allergies and a great way to create a fresher-feeling indoor air environment in general.

This dehumidifier is perfect for those living in medium to large homes – spaces up to 64m² are well served by this particular model. It can also be used in unheated basements or cellars.

If you're looking for something ultra-quiet in the bedroom, we'd recommend the Meacodry Abc 12l Compressor Dehumidifier instead.

Best mid-range dehumidifier

The ProBreeze 20L Premium Dehumidifier offers a powerful and user-friendly solution to combat damp and humidity in your home, especially if you live in a listed or poorly ventilated property.

We found this appliance easy to set up and its significant water extraction (up to 20L daily) noticeably improved the air quality in the home within a matter of days. Despite a somewhat noisy operation, benefits such as laundry mode, automated humidity detection, and an economical running cost make its mid-ranged price a worthwhile investment.

Another benefit of this model is its other operating modes including strong, natural, ventilation and continuous. In addition, this dehumidifier has a safety child lock to deactivate all buttons and a sleep mode that will turn all the lights off for undisturbed sleep.

However, if you want to use your dehumidifier in a cold room, such as a garage or basement, the EcoAir DD2 Simple Desiccant Dehumidifier or Meaco DD8L Pro Desiccant Dehumidifier will be a better choice.

Best compact dehumidifier

Despite being only 40cm in height, the MeacoDry Arete One 6L Compact dehumidifier packs a punch when it comes to performance. When Homebuilding’s Web Editor Amy Willis put it to the test, she was particularly impressed with how well it dried her laundry, how easily it could be moved from room to room, and how conveniently it could be placed on worktops out of the way of foot traffic.

It might have a smaller tank size than regular dehumidifiers, but you shouldn’t underestimate its power – Amy found it plenty big enough for her double-sized bedroom and helpful for tackling condensation, drying clothes and reducing humidity levels in her bathroom.

The model is quiet enough for an undisturbed night’s sleep (running at 32 dB) and comes with a free HEPA filter, allowing it to double up as an air purifier.

This dehumidifier also has excellent energy efficiency, running at 101 watts and costing around 3p per hour based on 26.35p/kWh energy pricing. When you compare it to the 12L model, which uses 151 watts, and the 25L model, which uses 67 watts, it puts into perspective how efficiently it runs considering it’s only a six-litre unit.

If you think you'll need a bigger tank size, the Meaco 20L Low Energy Dehumidifier and Air Purifier is a great alternative.

Best dehumidifier for drying laundry

Although the De'Longhi DEX212F 12L Tasciugo AriaDry Dehumidifier is on the more expensive side, its sleek appearance is matched by its performance when it comes to drying laundry.

Fast, surprisingly quiet and efficient at drying clothes – leaving them feeling softer than when dried on a heated airer – our tester, Sarah Harley, found that a few downsides are that it's on the heavier side (10.3kg) and doesn't have a humidity level display like some of the other models.

If you're after something more lightweight, the MeacoDry Arete One 6L Compact Dehumidifier is an excellent alternative that can also be used for laundry but weighs just 7.9kg.

However, if you live in an apartment, meaning your drying options are limited to heated airers or tumble dryers, we feel that it is definitely a purchase worth considering.

Best dehumidifier for cold rooms

The EcoAir DD2 Simple Desiccant Dehumidifier is suited to colder spaces and has a powerful, yet relatively energy-efficient, wattage. With an automatic shut-off, anti-tilt safety function and a continuous drainage outlet, our tester Amy Willis believes that it's a good option if you are looking to leave it running in spaces such as garages.

Although it doesn't show humidity readings of the space you use it in, we found it to be, nonetheless, fast, efficient and light enough to move around if you're struggling with damp in a number of areas.

It's also fairly quiet to run, operating at 37-46dBa, making it suitable to use inside if your property struggles to get warm. Amy was also impressed by its "very powerful" laundry mode which extracted moisture from the air and was easy to select on the settings.

Best dehumidifier for bedrooms

Specifically chosen for testing in the bedroom due to its Quiet Mark rating and sleep function, we found this dehumidifier to be suitably quiet. While initially noisy when starting up, the fan quickly reduced to a low hum, making it easy to fall asleep while it works – even for light sleepers!

If you're looking for an affordable solution to window condensation in the bedroom, this could be a great option to consider. It also made the room feel warmer and the generous 12L tank capacityDe'Longhi DEX212F 12L Tasciugo AriaDry DehumidifierDe'Longhi DEX212F 12L Tasciugo AriaDry Dehumidifier meant it was still working when our tester, Sarah Harley, woke in the morning.

There are two options for reducing humidity: continuous extraction until you turn it off (which is recommended for drying laundry), or auto switch-off, which turns off once you've reached your desired humidity level and tests the air every 30 minutes.

Best dehumidifier for garages

If you're looking for a solution for a cold, damp garage, the Meaco DD8L Pro Desiccant Dehumidifier comes highly recommended by Amy Willis. She put it to the test to see if it could prevent condensation, damp and mould from damaging her stored items in the garage, and was very impressed with the results.

One of her favourite things about this model – and a big reason why it's so good for garages – is that it comes with a wall mount to help keep it out of the way. This was particularly handy considering the dimensions were quite bulky, measuring 38cm x 36cm x 23cm.

It can extract up to eight litres of water per day and has a two-litre collection tank, as well as the option for continuous drainage. While it doesn't come with a hose, Amy says that you can fit a garden hose as an alternative.

The Meaco DD8L Pro can also be connected to your phone, allowing you to monitor the water tank and humidity levels remotely, which Amy found "useful but not essential".

It might be on the expensive side of dehumidifiers, but Amy says this model is "perfect for garages" and liked how you can tailor it to your space via the adjustable power settings. For something (slightly) more affordable, we also recommend the EcoAir DD2 Simple Desiccant Dehumidifier.

Best smart dehumidifier

There’s a lot to like about the Duux Bora 20L Dehumidifier, which features an eight-litre daily extraction, a quick-drying laundry mode and a practical, portable design. But what makes this model stand out are its advanced smart features, which let you control it remotely from your phone or voice assistant.

When Homebuilding's news editor Joseph Mullane put it to the test, he connected the dehumidifier to the Duux app, which allowed him to set up to seven schedules and track his indoor air quality. He also liked how it integrates with Google Assistant and Amazon Alexa for easy, hands-free control.

Smart features aside, this dehumidifier has been a “game-changer” for reducing damp in Joseph’s home, thanks to its 20-litre extraction capacity and the hygrostat, which ensures humidity levels stay perfectly monitored.

He also found this dehumidifier fantastic for drying laundry and appreciated the continuous drainage hose for easy emptying and the roller wheels that make it easy to move from room to room.

The only drawback is that it can be slightly noisy when on the highest extraction rate, so if you plan on sleeping with a dehumidifier, the MeacoDry ABC 12L Compressor Dehumidifier is a better choice.

How to choose the best dehumidifier

Finding a dehumidifier that meets your needs and wants depends on the type of moisture that you’re trying to remove. A general rule of thumb is the larger the dehumidifier, the more powerful it’ll be.

According to Chris Michael, co-founder of Meaco, you'll need to consider the following factors:

1. Size of the property
You'll need to match the extraction rate to the size of the property:

• 6L: room only dehumidification 
• 10L: suitable for a small, two-bedroom flat
• 12L: recommended for a two-bedroom house
• 20L: suitable for a three-bedroom house
• 25L: recommended for properties with more than three bedrooms

2. Moisture levels
"If the property has high moisture levels due to damp issues, a high number of occupants, or regular indoor clothes drying, it’s best to choose the next size up. A more powerful model will remove moisture faster and more effectively."

3. Room temperature
"Compressor dehumidifiers perform best in heated homes, while desiccant dehumidifiers are better suited to cooler conditions, such as in a basement, conservatory or garage. The key temperature is 15°. Below this, go for desiccant, above 15°, go for compressor."

4. Energy efficiency
"Electricity consumption is an important consideration for an appliance that may run for much of the year. Models with a built-in humidistat are recommended, as they can be set to reach a target humidity level and then switch off automatically."

5. Noise levels
Be sure to check the decibel rating before investing in a dehumidifier. Models with Quiet Mark accreditation are a good choice for places like bedrooms.

6. Quality versus low-cost models
"While cheaper models may have a lower upfront cost, they are often less energy efficient and may not last as long. A higher-quality model can offer better long-term value through lower running costs and greater durability. Indicators of quality include longer warranty length, independent media reviews, and strong consumer ratings."

When won't a dehumidifier be suitable?

If your damp issue is the result of bad ventilation and lots of condensation, a dehumidifier can definitely help. That said, if damp is a persistent issue, caused by other factors concerning the structure of your home, a different and more involved solution is going to be required long term.

A dehumidifier will still help the situation but building work to fix the issue will be a better solution. Start by looking at the causes of mould in a house to help you figure out what could be the root of the problem.

Dehumidifiers play a crucial role in maintaining a healthy and comfortable living environment, especially in homes grappling with damp and humidity issues. But if you're in the market for a new dehumidifier, selecting which one to buy can be a bit of a headache.

The choice between a budget dehumidifier versus a premium dehumidifier isn't exactly straightforward, as both options have their pros and cons. To help solve this dilemma, we put two popular dehumidifiers on both sides of the price scale to the test: The ProBreeze 20L Premium and The Hysure 700ml Automatic.

So, which one will come out on top in the battle against damp? Keep reading to find out how these two models compare in terms of price and performance.

Budget dehumidifier vs Premium dehumidifier

The ProBreeze 20L Dehumidifier is available to buy on Amazon this Black Friday for £219.99 (ordinarily £249.99), firmly placing it in the category of a 'premium' dehumidifier.

In contrast, the Hysure 700ml Automatic Dehumidifier is currently available to buy on Amazon for only £49.99. You can also purchase the same model of the Hysure in black on Amazon Prime or get a larger 2L Hysure on Amazon for a bit more money

On price tag alone, the budget Hysure model takes an early lead.

First impressions of both dehumidifiers

Once you get over the premium price tag, there's no doubting that The ProBreeze 20L Dehumidifier is an impressive piece of kit. It's large (350 x 200 x 608mm) but not too heavy, and setting it up is a breeze (no pun intended). Wheels at the bottom are also a nice touch – making it easy to move it from room to room when required.

By comparison, the Hysure 700ml Automatic Dehumidifier is small but promising (163 x 107 x 267mm). It’s super lightweight and the design is pretty sleek. What's more, even though it's small in size, it doesn’t feel flimsy or poorly made.

When it comes to first impressions, both dehumidifiers are evenly matched.

Specifications

The ProBreeze is a bit of a powerhouse, pulling 20L of moisture from the air each day. It's got a hefty 5.5L tank and various modes, including a special laundry mode for drying clothes when you can't hang them outside. Its large capacity makes it perfect for reducing humidity in your home. 

The much smaller Hysure model extracts about 300ml of moisture a day with a 700ml tank. There are no special modes on this model, so it's better suited for modest damp issues, such as window condensation.

In terms of specs, the ProBreeze is a clear winner.

How well do they work?

As someone who lives in a listed building, the ProBreeze was a game-changer. It was able to reduce the conditions in my home to normal humidity levels, making the air feel fresher. The noise of this model is noticeable, but it's a small price to pay for dryer walls and cleaner air.

The Hysure, while not as mighty, held its own in smaller rooms and had a positive impact on reducing the mould on my skirting boards. However, its relatively small capacity makes it ineffective in larger spaces.

In terms of performance, the premium dehumidifier wins again.

How much do they cost to run?

Dehumidifier running costs will vary depending on the size and spec of your model.

According to the website, the premium ProBreeze dehumidifier claims to cost just 14p per hour in operation costs. However, mine seemingly cost around 8p per hour, making it an extremely cost-effective model for its size and performance.

Similarly, the Hysure 700ml Automatic Electric Dehumidifier is fairly inexpensive to run, costing mere pennies each day.

When it comes to running costs, both dehumidifiers score highly.

Which dehumidifier is best?

The ProBreeze is ideal for more serious damp issues and is a valuable investment when you consider the long-term savings you would make as a household fighting high humidity and condensation. 

The Hysure 700ml compact dehumidifier performs well for its size and the budget price. However, I don't feel that it made a significant impact on my mould or damp issues. It has also since broken, which may be due to my lack of dehumidifier maintenance and cleaning – or it might be a symptom of being the cheaper option. Either way, had I registered my warranty online, I would have been entitled to a replacement unit.  

Based on the above comparisons, it's clear that the premium dehumidifier comes out on top overall. However, both models have their place depending on your budget.

Whether you opt for a budget model or a premium one, dehumidifiers are a great way to reduce condensation and mould in your home. However, to truly eradicate these issues, you need to address any underlying issues by treating damp at the source and ensuring you have proper home ventilation. 

As much as I love period properties, with all their charm and history, as anyone living in one will tell you, they are not without their issues — condensation on windows being one of them. 

My house is an Edwardian cottage and, despite having renovated it and brought it largely up to modern standards, it is a cold house, with cold floors and, in all honesty, could probably do with an insulation upgrade. In short, it is draughty, pretty badly insulated and has single glazing in several rooms. 

As such, once the temperatures start to fall, our windows in the bedrooms and living room are running with condensation, which pools on the window cills and around the glazing bars. We have to mop them up every single morning to prevent damp forming, although black spotty patches around the windows and behind curtains are not a rare sighting.

Having written extensively on the subject of condensation, damp and mould over the years (the glamour!) I have often come into contact with industry experts, all of whom sing the praises of dehumidifiers and the role they can play in helping to reduce or eliminate condensation — so I decided to see if they were right. 

What was the condensation in my house like?

As I've said, the condensation problem on our windows is pretty dramatic on a cold morning. All the bedroom windows on the first floor are running with condensation from about the beginning of October onwards (depending on the temperatures of course). 

We duly open the windows in the hope of reducing the risk of more damp, before getting to work with old cloths to mop up the running water and protect cills and walls. 

Although the ground floor is not as badly affected, at times the single-glazed bay window in the living room is also streaked with condensation when we pull up the blind in the morning.

The newer, extended section of the house mostly seems to escape the problem.

How did I test the dehumidifier?

Having looked at the Meaco 20L Low Energy dehumidifier review, this is the one I decided to give a go.

This model costs around £259.99. Despite my fears, it was really easy to set up and before I knew it I was staring at a relatively humidity reading of almost 90. Given that the average humidity inside UK homes should be around 50-55%rh, this left me feeling a little alarmed in all honesty and keener than ever to get the machine up and running. 

I switched it on, set a relatively humidity target of 55% and let it do its thing. In fact, I left it running the whole afternoon and then refused to turn it off at bedtime, much to the annoyance of my husband who said he wouldn't be able to sleep with the fan running. 

We compromised and set the fan to low — honestly, the noise didn't bother me one bit. However, I was woken in the early hours of the morning by my husband fumbling around in the dark to turn it off...

Despite these nocturnal activities, when I opened the curtains in the morning, there was not a single drop of condensation on our windows! Interestingly, there was also none to be found on my son or daughter's windows where there usually is, despite both their bedroom doors being shut overnight.

The following day I placed the dehumidifier on the landing during the day, for around six hours and turned it off at bedtime. I admit I had a problem with this. We all sleep with our bedroom doors closed and I couldn't wrap my head around how this would work. And you'll never guess what — still no condensation in the morning. Witchcraft. Clearly the moisture the machine had been dealing with during the course of the day and into the evening had been contributing to the morning condensation.

Did the dehumidifier help dry our laundry?

Our other problem in our home is a lack of space in which to dry laundry. While we have an airing cupboard with a hanging rail which is great at drying out some clothes, with two sports-playing teenagers, the dirty washing basket is never empty so we also have to use radiators and a sizeable drying rack in addition to the airing cupboard. 

I had previously wondered do dehumidifiers dry clothes and having asked Meaco they were keen to stress that they can. All this damp washing hanging around does nothing to help with the condensation and moisture levels in the air so it is fair to say I couldn't wait to test out this aspect of the dehumidifier. 

Although Meaco suggest placing the dehumidifier in a small room with the wet washing and state it is best to keep the door closed, the best I could do was to pop the machine in our bedroom, around a metre and a half away from the clothes rack.

Where a clothes rack-full of washing would normally take around a day and a half to get fully dry inside in our house, with the dehumidifier running, the washing took roughly five hours to dry. Strangely I also noticed that the washing hanging in the airing cupboard, which has louvred doors and is also located on the landing, was drying much quicker. 

Did the dehumidifier cost us much to run?

One of the main concerns we had was over dehumidifier running costs — would our newly condensation-free house cost us a fortune?

When calculating dehumidifier running costs, you need to take the model's power rating and find out how much you pay for electricity per kWh. The new Energy Price Cap rates from 1 October to 31 December 2023 stand at 27.35p per kWh.

Dehumidifiers are rated in Watts (W) — this is the amount of power they use. 

Our model has a power consumption of 219 watts at 20°C and 60% relative humidity.

To establish how much it would cost to run, we used the following calculation:

0.219kWh x 27.35p = 6p per hour. We have been running the dehumidifier for between 8-10 hours per day, meaning we are spending roughly 48-60p per day. I was really pleased to hear this and felt that the results were well worth it. 

How often did the water tank need emptying? 

I was worried I would spend all day running to and from the bathroom to empty the water tank to begin with. For the first few days, when running the dehumidifier for between 6-8 hours, we were having to empty the tank around once a day. After a month of using it, however, it only needs emptying once about every three days. 

When the tank is full, the machine sounds a beep and switches itself off. 

Will I continue to use the dehumidifier? 

Yes, yes and yes. I can't tell you how nice it is not to have to set aside 30 minutes or so every morning to mop down windows of their condensation. In terms of mould spots on the walls, we tend to wipe these off as soon as they have appeared and while it is perhaps too soon to say whether or not the dehumidifier has helped with this, no new ones have cropped up in the time that we have been testing it. 

Laundry is drying faster, the air quality in the house somehow feels better, upstairs feels noticeably warmer (something that greatly pleased our son on getting out of the shower and stepping into our usually chilly landing) and our windows are no longer sodden. 

When Kevin McCloud said a cheap air conditioning trick was to mop a floor, I was intrigued. 

The logic is to do with evaporative cooling, a natural process that also happens to be how air conditioning works. What happens is that as the liquid water evaporates into a gas, it uses heat in the air as an energy source. As a result, the heat loss causes the air to cool.

But it got me thinking – could similar be true with higher humidity in a house during winter? Could more water in the air make it feel colder? And. therefore, could less water in the air be a bit of an energy saving tip?  

I decided to test the theory using a dehumidifier to lower the humidity levels in my home and see if it helped me keep the thermostat turned down and the central heating off, saving energy and potentially money on my energy bills.

Does high humidity in cold weather make it feel colder?

First things first, I did some investigating to see if there was any truth in this idea of higher humidity in cold weather making a room feel colder. And apparently this is true – although not, as I initially thought. It turns out that humidity levels can not alter the temperature of a room, but, while higher humidity won't change the room's temperature, it will change how warm you feel.

This is because humid air has a higher water content. This makes it more difficult for a body to keep warm because it is harder to transfer body heat to water than it is to air, a blog for Brennan's Heating and Air Conditioning explains.

"The process of moisture evaporating off your skin naturally cools you down. Your body won’t sweat when it’s cold, but humidity from the air can place moisture on your skin and give you the same chilly effect," it said.

Essentially, the warmth from your skin is being used as the energy source for evaporative cooling, which is great in hot weather but that heat loss doesn't feel so great with colder conditions. 

Did running a dehumidifier make me feel warmer?

The next step was to put the science to the test. My home is a classic example of a historic cottage that generally feels cold all year around – great in summer but much less beneficial in winter. I have single glazing too, with large air gaps around the windows downstairs and large, cold stone flagstones in my kitchen, where I usually work. 

To test the theory, I ran a Meaco 20L low energy dehumidifier 24/7 in my home for two weeks. I was immediately surprised to not feel cold as temperatures started to gradually drop during that time. The humidity reading on the dehumidifier came down to 55-60%rh after an initial and rather alarming reading of 88%rh. I later discovered that a high initial reading is not unusual when first turning on a dehumidifier.

As my hallway thermostat nudged 15°C, I didn't feel the need to turn the heating on or light the log burner until it dipped to 12°C. Meanwhile, overnight, I happily left the heating off all night without feeling cold getting up in the morning. 

Having felt comfortable during the first two weeks of using the Meaco 20L low energy dehumidifier, I dared to switch it off overnight and into the next day to see if I noticed the difference. 

And I've got to say that despite the thermostat still reading a similar temperature, a positive chilly 14°C, I felt like I was sitting in a large industrial fridge as I tried to get on with my day's work. I was not only shivering but the air felt cold inside my clothing. In fact, five minutes into my day, I gave up and switched the heating on because frankly shivering while you try to type is not a lot of fun. Switching the dehumidifier back on, it was reading around 72%rh so I do put this discomfort down to the humidity level rising back up.

How expensive was the dehumidifier to run?

The cost of running the dehumidifier 24/7 does of course come with a price tag, and this was something I was conscious of throughout the experiment.

Dehumidifier running costs do vary between models but the Meaco 20L low energy dehumidifier that I was using has a power consumption of 219 watts at 20°C and 60% relative humidity. 

With the energy price cap standing at 27p per kWh, from 1 October to 31st December 2023, this put the running cost of the dehumidifier at 5.9p an hour (0.219kWh x 27p = 5.9p).

So for 24 hours worth of use, the dehumidifier cost me £1.42, and for 14 days of use 24/7 it cost £19.88. However, that's not taking into account the dehumidifier automatically shutting off when it reached the desired humidity of 55%rh or when the 20L tank became full. It's also worth pointing out that my house is particularly leaky so a more modern, well insulated house is likely to only need the dehumidifier on for perhaps 12 hours rather than 24 hours like I was running it.

Were there other benefits to running the dehumidifier?

During the two weeks running the Meaco 20L low energy dehumidifier, I also stopped needing to use my tumble dryer. Instead, I could set up a clothes horse in the kitchen near the dehumidifier and be confident that the items would be dry by morning. 

Prior to the dehumidifier, clothes would often take a good two or three days to dry like this, making the tumble dryer essential to avoid musty smelling socks and tops.

I have a condenser tumble dryer, so my tumble dryer running cost is around £1.44 a full load (based on an estimated 5.34kWh wattage) meaning that running the dehumidifier did save me money on this. To put a figure on this, I was using the tumble dryer about three times a week without the dehumidifier at an estimated cost of £8.64 over a two week period. With the dehumidifier running, I only used it once (due to speed mainly) costing me £1.44. 

The other benefits were difficult to put a value on but included reducing condensation on the windows upstairs (downstairs the huge gaps sort this out) as well as reducing any chance of mould taking up residence in the home. This particular dehumidifier also has an air purifier on it too, which given that I live next to a busy road, I felt was a nice added bonus.

Did the dehumidifier save me money on energy bills?

Running the dehumidifier 24/7 for two weeks cost me an estimated £19.88 in energy.

Working out the saving on central heating was a little more tricky, as I generally put more jumpers on, light the log burner and try to endure the cold rather than turning the heating on in the days before using the dehumidifier. This of course isn't helpful when trying to draw a comparison, however, looking back at my Nest report for November 2022, I used 97 hours of heating, which works out at three and a half hours a day or 46.2 hours for two weeks.

Meanwhile, over the two-week period running the dehumidifier, looking at my Nest report, I used an average one-and-a-half hours a day of central heating, which worked out as roughly 22 hours of heating for two weeks — under half the amount.

With central heating costs per hour based on an average 10,000kWH usage an hour,  boiler running costs are 8p an hour with both gas or oil, based on the current energy price cap gas rate of 7p per kWh and an oil price of 77p per litre.

Therefore with tumble dryer costs, central heating costs and dehumidifier running costs considered, my energy cost without the dehumidifier was a total of £12.34 — £3.70 in oil central heating and £8.64 in tumble dryer costs.

Meanwhile, my energy costs with the dehumidifier running were a total of £23.08 — £19.88 for the dehumidifier, £1.76 for oil central heating, and £1.44 for the tumble dryer. 

Essentially the dehumidifier cut my energy usage by a half, but despite this, did not reduce my energy bills.

Will I keep using the dehumidifier?

Interestingly and perhaps surprisingly, based on current energy prices, running the dehumidifier did not save me any money on my energy bill. It cost me more. 

That said, if the price of oil and gas went up and the price of electricity went down, this might become more of a saving than a cost, as running the dehumidifier definitely reduced my energy usage, not to mention feeling much warmer and comfortable while working from home.

Ultimately, however, the additional cost to run the dehumidifier — taking into account my energy savings (mainly on the tumble dryer) — was £10.74 for the two-week period. For that price, I will definitely be continuing to run it. Not only to feel warmer while working from home but for drying laundry and getting rid of that condensation upstairs.

Although the overall purpose of a humidifier vs dehumidifier is in essence the same – both manage moisture levels in your home to help improve air quality – there's a fundamental difference that can cause problems for you, and your home if you pick the wrong product.

With one adding moisture and the other removing it, pick the wrong appliance and you could end up exacerbating issues such as damp, or compounding problems with dry air that can impact both you, and your home's structure.

So how do you know which one you need? We explain the key differences between a humidifier vs dehumidifier to help you make a considered purchase.

Humidifier vs dehumidifer — what's the difference?

As identifying the difference in the products by name is only marked by the use of two different letters 'de', understanding how each one works is important to establish the main differences between a humidifier vs dehumidifer.

"In basic terms, a humidifier adds moisture to the air, while a dehumidifier removes it," explains Chris Michael, managing director of Meaco.

A humidifier’s primary function is to introduce moisture into the air, creating a more hospitable and health-friendly environment, particularly in settings where dry conditions prevail.

On the flip side, a dehumidifier works by extracting moisture from the air, a crucial function in damp indoor spaces to prevent the growth of different types of mould and mildew.

Signs you need a humidifier

While dry air may feel less problematic than damp air, it can still be a problem, particularly from a personal health point of view, and also if you have a lot of timber in your home – including as part of its structure.

Indications that the air in your home is too dry include:

• Respiratory issues
• Dry eyes or throat
• Frequent static electricity
• Cracking wooden furniture and fixings like solid oak doors
• Wilting houseplants

In these scenarios, a humidifier,can help restore your home to normal levels of humidity, creating a more comfortable living environment.

Signs you need a dehumidifier 

While a humidifier increases levels of humidity in your home, a dehumidifier works by reducing humidity levels in your home.

According to Chris Michael, signs you may need a dehumidifier include:

• Condensation on windows, particularly in the mornings
• Pooling water on windowsills and walls that feel damp to the touch
• A musty smell that lingers
• Mould or mildew on walls, ceilings or behind furniture
• Wet washing takes a long time to dry when hung indoors
• Worsening allergy symptoms triggered by mould spores or dust mites

"Perhaps the most obvious red flag you need a dehumidifier is if you see any black mould forming on your walls or ceilings," confirms Katie Lilywhite, air treatment expert at AO.com. "This shows your home is struggling with humidity and a new dehumidifier might just be the breath of fresh air your home needs.”

And, if you have already spotted signs of damp, there's no doubt a dehumidifier will help, adds Katie.

“Dehumidifiers are the perfect appliance to get rid of and help prevent damp from reforming. They work by drawing in excess moisture from the air and collect this in a tank rather than recirculating it like a humidifier. This can help to stop mould growth, and reduce any damp patches that may have formed on your walls and ceilings.”

To accurately determine whether a dehumidifier is the right choice for your home, also consider factors such as climate, season, and specific areas of your home. Basements which are cold, for instance, are prone to dampness and might benefit from a dessicant vs compresser dehumidifier.

Humidifier vs dehumidifier – which is better for allergies?

If you're experiencing respiratory issues, you could be looking at ways of making the air in your home cleaner. While products such as the Molekule Air Pro will certainly help, managing the moisture levels will also bring comfort if you're suffering with allergies.

If you’re experiencing persistent dry skin, nose bleeds, irritated eyes, or throat discomfort, these could be signs that your indoor air is too dry and you require a humidifier. A humidifier can also reduce the likelihood of nosebleeds and help alleviate symptoms of the flu or common cold.

However, sometimes respiratory issues and allergies are actually indicators of damp and excess moisture in the air, not dry air. In such cases, a dehumidifier would help alleviate these issues more effectively than a humidifier.

“If you’re perhaps suffering from hayfever then a dehumidifier will always be the ideal appliance to help comfort you at home," says Katie Lilywhite. "Cleaner air can be hard to come by in the summer months when pollen is up, but this is made short work of by a HEPA filter. These are designed to catch pollutants in your home and help to provide hayfever or asthma sufferers relief.”

Identifying the cause of your allergies with a medical expert is always recommended too, as this will impact on your choice of humidifier vs dehumidifier.

"Some allergens thrive at low relative humidities and some at high relative humidities," advises Chris Michael, "but maintaining a steady relative humidity (rh) around 55%rh will be the best compromise for everyone's health and to prevent static, damp and condensation issues."

A hygrometer, like this inexpensive ThermoPro hygrometer from Amazon, can be a useful tool in measuring indoor humidity levels, helping you maintain a normal level of humidity within the home.

FAQs

Will putting both appliances in the same room negate their purpose?

"Where you use both a dehumidifier and a humidifier in the same room you would set the humidifier humidistat to 50%rh and the dehumidifier humidistat to 60%rh," advises Chris Michael.

"You then have a ‘dead’ zone between 50-60%rh where neither machine is on. This is the proven technique that museums have used for control for decades which can be applied in the home."

Will using a humidifier make your home damp?

"Only ever use a humidifier that has a humidistat on it to prevent it from over-humidifying your space," warns Chris Michael. "There are two types of humidifiers available on the UK domestic market, ultrasonic and evaporative.

"Museums only ever use evaporative humidifiers, because, if the humidistat fails, the physics behind the technology means that they will never over humidify the space, whereas an ultrasonic can take the room's relative humidity up to dangerous levels."

While humidifiers offer numerous benefits, they are not without their potential downsides. If not cleaned regularly, they can also become a breeding ground for mould and bacteria, which are then dispersed into the air, potentially leading to respiratory issues. Proper maintenance, regular cleaning, and monitoring humidity levels are essential.

Are there spaces where you shouldn't use a dehumidifier?

“For the most part, dehumidifiers are safe and useful in most parts of the house but there are a few exceptions and things to be mindful of," advises Katie Lilywhite.

Your kitchen can get quite warm and steamy so while a dehumidifier can help, good ventilation is far more effective. A good cooker hood will do a better job, but should your kitchen have a persistent damp issue then this is where a dehumidifier can excel," she explains.

Using dehumidifiers in a bathroom also needs to be treated with care. The UK electrical guidelines permits items being plugged in and used within the room. While it can be placed outside the door and will certainly extract moisture, "steam from showers can overwhelm some dehumidifiers," says Katie. "As such you’d be better off using the best bathroom extractor fan you can and opening a window after running it.”

In summary, choosing the right appliance has tangible benefits for both your health and comfort. You should purchase a dehumidifier if you want to help treat damp and prevent mould growth in your home. A humidifier is required for particularly dry conditions, and can soothe irritated skin and respiratory passages, as well as preserving the condition of your belongings.

The Meaco 20L Low Energy Dehumidifier/Air Purifier is designed to help control humidity levels in a house, reducing or even eliminating window condensation and, subsequently, minimising the risk of damp.

It also offers further benefits. It can help to dry laundry quicker and, thanks to its HEPA filter, can also purify the air — ideal for those with allergies, but also a great way to create a fresher-feeling indoor air environment in general. 

This dehumidifier is perfect for those living in medium to large homes —  spaces up to 64m² are well served by this particular model. It can also be used in unheated basements or cellars. 

So, just how well does it live up to its claims, is it easy to use and is it worth the initial outlay and running costs further down the line? 

Does the Meaco 20L Low Energy Dehumidifier/Air Purifier work well?

Having tested the 20L Low Energy Dehumidifier, available to buy on Appliances Direct, over the course of four weeks at the time of writing this review, we can confirm that it has performed brilliantly, both at reducing condensation and also in reducing the drying time of damp laundry. 

It was easy to set up and proved excellent at pretty much eliminating the condensation on the windows of the first floor bedrooms in the house we tested it in. 

While it is a sizeable piece of kit, being set on castors made it easy to move around and the water tray couldn't have been simpler to remove and empty. While we were mainly focussed on the effect that this dehumidifier would have on the condensation problem the house was suffering from, we were also impressed with the way in which it sped up the time it took to dry wet washing. 

While not the cheapest product on the market, this is one high-quality and well-made piece of equipment with a host of useful extra features — plus its low running costs make it far cheaper to use than many of the alternatives out there. 

Is the 20L Low Energy Dehumidifier easy to set up?

While this dehumidifier is pretty large, it isn't too heavy and comes in a box with carry handles. Once it is out of the box, it is easy to move around thanks to the castors underneath. 

Set up couldn't be simpler. The instruction manual is clear and the controls are simple and, in all honesty, pretty self-explanatory. 

Once plugged in, the machine can be switched on, activating the digital display. The target humidity level can then be set — another very simple task. So, what is normal humidity in a house? 

“The average humidity inside UK homes should be around the 50-55%rh range and be slightly lower in winter months,” says Chris Michael, MD of Meaco. “Maintaining a humidity target of 40% in the winter will keep condensation from forming on your windows.”

With that in mind, by using the up and down arrows, we set the target at 55. We also selected the 'CO' mode. On this mode, the dehumidifier runs continuously. You could also choose to select 'AP' mode, although this just purifies the air as opposed to collecting any water. 

We were testing this dehumidifier in an old house that was prone to condensation and when the machine first started running, the relatively humidity showed as being 80%.

How does the Meaco 20L Low Energy Dehumidifier work?

How do dehumidifiers work? At a very basic level, they remove excess moisture from the air — something that helps reduce condensation and, in turn, damp. They can also help to dry wet laundry faster.

"A dehumidifier removes moisture from the air — excess moisture that you do not want to condense and hang around your home," says Chris Michael. "It helps to ease damp problems, gives you healthier air to breath and can even make your energy use more efficient.

"There are two main types of dehumidifier — the desiccant dehumidifier and the compressor dehumidifier," explains Chris. The Meaco Low Energy Dehumidifier we are testing is a compressor model.

Compressor dehumidifiers are best for anyone aiming to prevent damp and help clothes dry quicker. They are ideal for use in areas with temperatures above 15˚C and they are cheaper to run than desiccant.

"They have two sets of coils, the first cools to create the condensation, which is collected into the water tank, the second warms the dry air back to just above room temperature," says Chris. "This helps to create the dry air needed to combat condensation, mould and damp problems."

How did we test the dehumidifier?

As mentioned previously, testing of this dehumidifier was carried out in a house that was suffering from window condensation and, as a result, signs of damp. The dehumidifier was initially placed in the room that the problem was worst — the master bedroom.   

The fan was set at high speed with a the target humidity of 55%rh and was left to run for around six hours, before being switched off overnight. 

Meaco suggest placing the dehumidifier was placed in a central position such as the landing or hallway, so the following day the machine was moved to the landing of the house where it was left to run for six hours once again. 

Did the dehumidifier solve the condensation?

Results time. Did the dehumidifier clear up the condensation problem? In a word — yes. When placed in both the bedroom and the landing and have been running for between 6-8 hours during the day, there was no window condensation the following mornings. 

Despite being on the landing for some of the testing and all bedroom doors being shut overnight, it still worked to reduce the moisture in the air to such a degree that the bedroom windows remained condensation free and were clear in the morning. 

The next day we kept the dehumidifier off all day. The result of this? The condensation was back the following morning .

How much does the Meaco 20L Low Energy Dehumidifier cost to run?

One of the main concerns of many people is dehumidifier running costs. 

When calculating dehumidifier running costs, you need to take the model's power rating and find out how much you pay for electricity per kWh. The new Energy Price Cap rates from 1 October to 31 December 2023 stand at 27.35p per kWh.

Dehumidifiers are rated in Watts (W) — this is the amount of power they use. 

Our model has a power consumption of 219 watts at 20°C and 60% relative humidity.

To establish how much it would cost to run, we used the following calculation:

0.219kWh x 27.35p = 6p per hour. We have been running the dehumidifier for between 8-10 hours per day, meaning we are spending roughly 48-60p per day. 

Does the dehumidifier dry clothes faster?

To test this we placed the dehumidifier in a room with a clothes horse-full of damp washing — around a metre or so away. Meaco suggest that to dry laundry quickly, the dehumidifier should be placed in as small a room as possible with the doors and windows closed.

We selected the louvre swing button mode to set the louvre in motion, distributing the air around. Meaco recommend using the louvre to direct the airflow towards laundry. The air coming out in this mode is a little warm.

With the dehumidifier running, the washing took roughly five hours to dry — a good four to five hours less than without. 

How often did the water need emptying?

When the water tank is full, the dehumidifier lets out a series of beeps and then switches itself off. There is also a series of three wavy lines that lights up on the digital display to indicate the tank is at its limit.  At this stage, you simply pull out the water tank at the front of the unit and empty it out — you can use it to water your plants if you like.

There is a carry handle on top of the water tank which make it easy to transport and tip out. 

This model has a tank with a capacity of 6L. Running on full speed for six hours, my dehumidifier collected 2.17 litres.

What is the HEPA filter for?

This dehumidifier comes complete with a HEPA filter, in addition to the regular filter that it was fitted with.

HEPA stands for High Efficiency Particulate Air. A HEPA air filter is made up of thousands of very fine fibres compressed into a mat which can grab both microscopic particles as well as bigger ones. The HEPA filter that comes with the Meaco dehumidifier I am using can capture up to 99.97% of particles that are 0.3μm or more. It is really simple to pop the HEPA filter in and, once in place, all the air going through the dehumidifier is purified — great for anyone who might be allergic (or would just prefer to avoid) mould spores, pollen, dust, pet dander or dust mites. 

What extra features does the dehumidifier have?

Aside from those already noted, this dehumidifier comes with several other useful functions that are worth noting. These include: 

• Memory function/Auto re-start: This one was very useful. It means that even when you turn the machine off, when you switch it back on it will continue to run in the same settings you previously had it running on meaning you don't need to reset the whole thing. 
• Meaco Control Logic: This useful features means that when the relative humidity in your room is at more than 3%rh below your target, the dehumidifier will stop drying the air. If the relative humidity is then stable, the dehumidifier will go to sleep for 30 minutes. After this time, it wakes up, samples the air and if it senses the air is now more than 3%rh above your set point, it will start to dehumidify again. If all is well however, it will go to sleep for another 30 minutes. Great for saving energy. 
• Child lock: This would be really useful for those with little ones who might be tempted by flashing lights and an array of buttons. With the child lock activated the functions of the dehumidifier cannot be changed. 

Is the dehumidifier noisy?

According to the manufacturer's specifications, this dehumidifier has a noise level at one metre of a maximum of 46dB(A) — but what is that like to live with?

During the day, being located upstairs, the noise was barely noticeable. At nighttime, when all was quiet, the low humming could obviously be heard. However, it wasn't overbearing and as we found there was no need to run the dehumidifier overnight to achieve the desired results this proved not to be an issue. 

Do we recommend the Meaco 20L Low Energy Dehumidifier?

The Meaco 20L Low Energy Dehumidifier and Air Purifier costs approx. £259.99. They also do a smaller model, the Meaco 12L Low Energy Dehumidifier and Air Purifier, which costs £189.99 and is more suitable for small homes and flats. 

While it is definitely not the cheapest model on the market, you need to factor in the fact that this is a low energy dehumidifier, making it cheaper to run than many of these lower cost products. For example, we also  recently carried out a ProBreeze 20L Premium Dehumidifier Review. While this model only costs £199, the website states it has running costs of 14p/hour — more than double our model.

As someone who lives in a listed building, getting rid of mould is often top of mind. As I mentioned in my recent review of the ProBreeze 20L Premium Dehumidifier, I've been fighting a constant battle with humidity levels and condensation causing mould on my walls for years, so I finally decided to invest in some decent dehumidifiers to tackle the problem. 

Having successfully got on top of condensation and mould in my home office, I turned to our guest bedroom where I required a much more affordable and compact solution. Thankfully, the Hysure 700ml Automatic Dehumidifier is available to buy on Amazon  for under £50 and it promised to be more energy-efficient, lighter and quieter than its competitors. 

Below, I share my thoughts on the performance of this affordable dehumidifier and whether I think it's worth the purchase. 

First impressions of the Hysure 700ml Automatic Dehumidifier

When I first opened up the box I was astonished by how lightweight this dehumidifier was – you can literally hold it up with one finger! It's a fairly sleek and modern looking dehumidifier, so it won't be out of place in a lot of homes. However, I believe you can also purchase the same model in black on Amazon Prime  if that's more your style. You can also buy a larger 2L version on Amazon for a bit more money too.

It's incredibly easy to assemble and get up and running. However, I wasn't too impressed by the short length of the power cable, as this made it difficult to position anywhere but against the wall. 

Specifications

• Brand: Hysure
• Material: ABS plastic
• Voltage: DC 9V
• Power: 23W
• Dimensions: 163 x 107 x 267mm
• Volume of tank: 700mL
• Efficiency: 300ml/day (at 30 ℃, 80% RH).
• Coverage: 15㎡
• Working temperature: 10-50 ℃

What features does the Hysure 700ml Automatic Dehumidifier have?

The Hysure 700ml Automatic Electric Dehumidifier is fairly limited in terms of its spec. However, it does boast the following features:

• Ultra-Quiet Technology: The Hysure dehumidifier uses 'peltier technology' with no compressor, making it extremely lightweight and quiet. It operates with minimal noise, allegedly allowing you to run it throughout the night without disturbing your sleep.
• Compact Size: This mini dehumidifier's small dimensions make it a convenient choice for a children's nursery or other small indoor spaces.
• 700ml Capacity Tank: The dehumidifier can extract up to 300 ml of moisture daily to help purify the air in small spaces.
• Energy Saving: The model brands itself as an environmentally friendly solution for absorbing damp and condensation in your home.
• Auto Shut Off: This portable moisture absorber automatically shuts itself off when the tank is full and ready for water to be emptied.

How well does it work?

In our guest bedroom we've been suffering from mould on our skirting boards. This is most likely caused by poor home ventilation allowing a build up of condensation and moisture to form in corners and behind furniture, resulting in mould growth. So I plugged in the Hysure 700ml Automatic Electric Dehumidifier and let it do its thing. 

The room is roughly 4m2 and I'm not sure if that strictly qualifies as a 'small' space, but based on the overall results, I'd say it doesn't. After running this dehumidifier in our home for the past 6 months, I've drawn the following conclusions:

Pros

• I've been impressed by its consistent performance. Unlike a similarly priced dehumidifier we had to return within 2 weeks of purchase as it broke, this one shows no signs of stopping anytime soon.
• This small dehumidifier lives up to its promise of quiet operation. The minimal ambient noise it generates doesn't disrupt a good night's sleep.
• Its compact and lightweight design makes it easy to disassemble and empty every few days.
• The automatic shut-off feature eliminates worries about your dehumidifier leaking all over the floor when you forget to empty it.
• In the corner where it was running I did notice a visible improvement to the mould on our skirting boards (see photos above). 

Cons

• The power cable is extremely short, so it has to be positioned close to a power source. 
• This model is suitable only for very small rooms. I ended up moving it into our 2m2 bathroom, as it didn't massively improve the condensation in the bedroom overall.
• If the noise doesn't affect your sleep, the LED light might. Unfortunately, there's no option to turn it off, so if you place this model in your bedroom, it will serve as an unintended night light as well
• 700ml is not a great deal of moisture and it takes roughly 2.5 days to extract this from the air.
• After 6 months of use I noticed a lot of discolouration inside the dehumidifier (see photos above).

How much does it cost to run?

Dehumidifier running costs will vary depending on the size and spec of your model. The Hysure 700ml Automatic Electric Dehumidifier is fairly inexpensive to run, costing mere pennies each day. This is particularly handy when you need to run it consistently. 

My thoughts on the Hysure 700ml Dehumidifier

This compact dehumidifier performs well for its size and has helped remove mould from the wall in places. However, if you have a serious underlying mould or damp issue in your home this is not the dehumidifier for you. The Hysure 700ml Automatic Electric Dehumidifier is an affordable dehumidifier priced under £50 and you should adjust your expectations accordingly. 

If price point is the main factor in your buying decisions then you can't go wrong with this model - especially if you're dealing with a minor condensation or occasional damp issues in a small bathroom or spare room. This dehumidifier is perfect if you're trying to achieve normal humidity in a house or you only have a small room to cover.

However, if you have significant issues with condensation then you should invest in a more serious piece of kit to ensure you have the best dehumidifier for the job. I recently reviewed a much larger and more expensive dehumidifier - the ProBreeze 20L Premium Dehumidifier available on Amazon - and I would recommend purchasing this model over the Hysure if you have a bigger home. 

An important update

Since I wrote this review my Hysure dehumidifier has broken. This is most likely because I failed to maintain the unit – following the manufacturer's instructions for cleaning and troubleshooting the problems I was experiencing. 

To avoid experiencing these issues with your own dehumidifier, I recommend weekly maintenance and cleaning. You should also ensure that you register your warranty online. If your dehumidifier breaks within its warranty you may be entitled to a replacement model free of charge. 

Dehumidifiers are a great way to reduce humidity, mould and condensation in your home. However, it is crucial to address any underling issues first by treating damp at the source and ensuring you have sufficient home ventilation to begin with. 

As someone who lives in a listed building, the ProBreeze 20L Premium Dehumidifier promised a solution to the pervasive nuisance of damp and mould that was plaguing my home.  

For the past few years, I've been fighting a constant battle with humidity levels in my home office, failing to get on top of the problem with cheap dehumidifiers and damp absorbers. So, when I read that the ProBreeze 20L Premium Dehumidifier – available to buy on Amazon – can remove up to 20L of moisture per day, I knew I had to give it a whirl. 

Below, I share my thoughts on the performance of this 'premium' dehumidifier and whether I think it's worth the price tag. 

First impressions of the ProBreeze 20L Premium Dehumidifier

The ProBreeze 20L Premium Dehumidifier is a sleek and surprisingly lightweight unit. I found the unboxing process to be hassle-free, as the box contained just the right amount of packaging, ensuring there was no damage to the product and avoiding excessive waste. 

Getting the dehumidifier setup was straightforward and intuitive. The ProBreeze comes with a clear drainage tube, a user manual, and four wheels that make manoeuvring the product around your home a breeze. I simply had to wheel it into my home office, remove the main power cord from the back and plug it in. 

It was a good first impression. Though this dehumidifier is not small, it's easy to move about and setup, and it isn't too much of an eyesore. 

Specifications

• Name: ProBreeze 20L Premium Dehumidifier with Special Laundry Mode 
• Type: Compressor 
• Filter: Washable nylon filter +carbon filter 
• Timer: 24 hr Max 
• Extraction: 20L 
• Dimensions: 350 x 200 x 608mm (LWH) 
• Weight: 13g 

What features does the ProBreeze 20L Premium Dehumidifier have?

With its promise of premium quality, I was keen to see what features the ProBreeze has. Overall, I'd say that the spec of this product really does hold water (and not just in the literal sense). Amongst its many functions, the ProBreeze has the following features: 

• 5 operation modes: Including 'strong', 'natural', 'ventilation', 'continuous', and 'laundry'. There's also a child safety lock for safeguarding these settings from little fingers. 
• Special laundry mode: During cold and wet months this mode is useful for drying your clothes indoors, as it absorbs atmospheric moisture and allegedly extracts up to 600% more water than other leading dehumidifiers (according to the ProBreeze website). 
• Cost-effective operation: The ProBreeze is an energy-efficient workhorse, extracting up to 20 litres of water daily, costing as little as 14p/hour to run.
• Automated humidity detection: Intelligent colour-changing LED humidity sensors monitor the rooms moisture levels, auto-regulating the unit for optimal humidity.
• Large water tank: The ample 5.5L water tank conveniently shuts off when full and the ProBreeze comes with a continuous drainage hose that can be inserted directly into a drain if required.
• Carbon filter: A detachable, washable carbon filter at the back of the machine ensures the air stays clean and healthy.

How well does it work?

Our old home, with its single-glazed windows and substantial granite walls, has long been a bastion for dampness. Over the years we've haemorrhaged money on cheap dehumidifiers and damp absorbers to no avail. 

Pre-ProBreeze, our home office was practically uninhabitable at times with damp walls collecting mould and condensation. But after one week of introducing the ProBreeze 20L Premium Dehumidifier we've experienced a marked improvement. There is visibly less dampness, a palpable freshness to the air, and crucially, dry floors and walls.

We didn't run the dehumidifier continuously but we still managed to empty the 5.5L tank five times and I was shocked to see that our humidity level had consistently been at an 80% rh level for some time (UK homes should be around the 50-55% rh range and be slightly lower in winter months). 

However, it's worth noting that the ProBreeze does generate a bit of noise – bearable during the day, but perhaps too intrusive for night-time operation.

How much does it cost to run?

When my friend first saw the size of the 20L ProBreeze she scoffed that it would cost me a small fortune to run, but the change to my electricity bill has been unnoticeable. Although the website proposes a 14p / hour operation cost, ours is seemingly costing us a mere 8p/ hour.

We typically never run the dehumidifier for longer than 2-3 hours at a time, due to its noisy nature. However only running it for a few hours a day still seems to do the trick and saves us quite a bit of money in the process. 

Should you buy the ProBreeze 20L Premium Dehumidifier?

As a long time damp sufferer, I absolutely recommend The ProBreeze 20L Premium Dehumidifier. Not only has it protected our belongings from the pervasive menace of mould but it has helped us to reduce humidity levels, and allowed us to use our home office again without worrying about our belongings being ruined by damp. 

At £199.99, it doesn’t position itself as the budget option and this may be a barrier to some homeowners. However, I view this dehumidifier as a valuable investment in regards to the long-term savings we'll make a a household fighting damp. 

A palpably fresher home and peace of mind makes this a 4.5 / 5 stars for me and worthy of a place on the best dehumidifier list! 

‘Does a dehumidifier heat a room’ is becoming a very common question as we look to find cheaper ways of heating our homes, and this question has a very simple answer: yes, it does, but only some very specific models.

Dehumidifiers are a surprisingly versatile appliance. As well as removing humidity and damp, they can be useful if you’re looking at how to stop condensation in your home as outdoor temperatures start to drop. But how effective are they as heaters?

Dehumidifiers naturally create a small amount of heat as they operate, and depending on the size of your room and how often you run your dehumidifier, you might experience a few degrees increase. 

It’s best to consider this heat as an effective source of background heating, rather than a primary heating source, but in certain situations you might be able to reduce the amount of heat required from other forms of heating, therefore lowering your heating costs.

How do dehumidifiers heat a room?

A dehumidifier naturally heats and cools air as it removes moisture, pulling moisture from the air then returning dried hot air which circulates through your room. This warming process is particularly noticeable in damp rooms with higher humidity, which will feel colder to be in.

But while dehumidifiers can make most rooms feel a little warmer, the differences between the two types of dehumidifiers are important to consider if you’re looking for more heating for your buck and to justify your dehumidifier’s running costs. 

A desiccant dehumidifier is the optimal choice for increasing your room temperature because it has an in-built heating element, which ensures that warm air is passed back out at a higher temperature than the air that is taken in. 

A compressor, meanwhile, features a rotary design that will still make a room more comfortable and less humid, but ultimately will not noticeably warm the air. 

When is a dehumidifier better than a heater?

You might think that a space heater is the clear, obvious choice when it comes to warming a room, but this is not always the case.

In particularly humid rooms - where it will feel colder than expected - a desiccant dehumidifier can be better value because it removes moisture as well as heating the air. A heater will warm you up, but it will not address the problems behind colder rooms. This can also be the case for older houses with poor insulation, where cold walls and windows can increase the risk of damp. 

However, in rooms that are generally well-insulated or larger spaces that require more heat, a space heater may be a better option. And in very cold periods, it is unlikely that a dehumidifier alone will be able to sufficiently warm larger spaces. 

Black Friday 2022 is the perfect time for anyone struggling with condensation on windows to snap up a bargain on dehumidifiers. 

Now that temperatures have really begun to drop, window condensation can be a real problem — not only does it look ugly, but it can also lead to all kinds of other issues, such as mould, damp patches and damage to window frames and sills.

Dehumidifiers can make a big difference when it comes to dealing with condensation, removing excess moisture from the air and replacing it with air at a slightly warmer temperature. 

Not only does this help tackle condensation, but if you are struggling to get wet clothes dry now that the outside washing line has been consigned to the garden shed for the winter, dehumidifiers can help speed up the drying process too.

We've been busy scouring the best Black Friday deals on dehumidifiers and have carefully selected the top five — get your hands on one fast and banish that condensation problem for good.

That said, there are, even at this early stage in Black Friday week, still some deals to be found — and we have rounded up five of the best.

Do dehumidifiers stop condensation?

If you have been wondering how to stop condensation, then a dehumidifier is very likely one appliance you will have been considering purchasing. 

But are they worth the money? Before buying a dehumidifier take the time to do your research. Dehumidifiers work by drawing in air, before passing it across a cold surface. This causes moisture in the air to condense, before the now moisture-free air is expelled back out into the room at a warmer temperature. 

To ensure you are pleased with your purchase, check what size of room the model you are interested in is suitable for. You should also be wary of some of the very cheap models around — if the water collection chamber is not properly sealed, the water within will be warmed back to room temperature before evaporating back into the house. 

Here, we answer the question, “How do dehumidifiers work?” so you can decide whether this is an appliance worth investing in.

Whether you're looking to stop condensation in your home, struggling with a damp problem, or – like so many of us right now – searching for ways to dry wet washing without running your tumble dryer, the best dehumidifiers might be able to help.

Whatever your reason for considering a dehumidifier, we’re here to explain the science behind them and how using one in your home could be the answer to all your excess moisture misery.

How do dehumidifiers work?

First things first, if you are thinking of buying a dehumidifier, it makes sense to look into exactly how they work and what they can be used for.

Although this is an appliance that often springs to mind for those looking at how to reduce humidity in a house, many people don't actually understand how it operates or the other benefits it can offer.

"The air in your home contains moisture. And you can add to this moisture by the things you do at home – cooking, showering, drying washing, and so on," says Chris Michael, founder and managing director at Meaco.

"When warmer, moist air hits colder air, the moisture condenses into water. That is when you start to notice damp and mould in houses, sometimes on walls and windows, and sometimes, more worryingly, on soft furnishings and even your clothes.

"A dehumidifier removes moisture from the air – excess moisture that you do not want to condense and hang around your home. It helps to ease damp problems, gives you healthier air to breath and can even make your energy use more efficient."

So, how does this work exactly? The specific process depends whether you have a desiccant vs compressor model (which we explain below), but both follow the same basic principle to extract moisture from the air. Here’s a breakdown of that process:

1. The dehumidifier draws in humid air using a fan
2. Depending on the model, it either absorbs the moisture into a desiccant material or cools the air so the water vapour condenses
3. The dry air is released back into the room, while the collected moisture drips into a storage tank

How do different types of dehumidifier work?

Desiccant dehumidifiers

Desiccant dehumidifiers are perfect for colder areas of the house, such as garages and storerooms – basically spaces where there is little or no heating. Here's how they work, according to Chris Michael:

1. The air is drawn in over a filter and passed over an absorbent material called Zeolite
2. When the material becomes saturated, a heater in the dehumidifier blows warm, dry air across the Zeolite, and the moisture condenses into water, which then drips into a collection tank
3. The warm air is then passed back out of the dehumidifier at a higher temperature than the air that was taken in, so this type of dehumidifier can also act as a gentle heater

Compressor dehumidifiers

If your aim is to prevent damp and help clothes dry quicker, a compressor dehumidifier is the model for you. They work best in areas with temperatures above 15˚C and follow this process:.

1. The dehumidifier draws in air using a compressor with a cold-coil system, like a fridge
2. The first coil cools the air to create condensation, which is collected in the water tank
3. The second coil warms the dry air back to just above room temperature. This helps create the dry air needed to combat condensation, mould, and damp problems

Will a dehumidifier stop window condensation?

Dehumidifiers are a great way to prevent or reduce window condensation. How effective they are at doing this relies on choosing the right type and the size of the model.

Of course, opening the windows in a room will also help with condensation, but in the depths of winter, do you really want to bring freezing cold air gushing into your home?

As we have discussed, dehumidifiers remove excess moisture from the air – moisture that would otherwise be deposited on your windows as condensation. Place your dehumidifier close to the window for maximum effect.

Do dehumidifiers stop damp?

When it comes to what causes damp, there are several culprits. However, a damp problem that has been caused by poor ventilation and excess condensation can most certainly be helped by the use of a dehumidifier.

That said, if damp is a persistent issue, caused by other factors concerning the structure of your home, a different and more involved solution is going to be required long term.

"The permanent use of dehumidifiers is a poor substitute for efficient heating and adequate ventilation when it comes to dealing with damp," says Douglas Kent, a chartered building surveyor specialising in building conservation and the technical and research director at the Society for the Protection of Ancient Buildings (SPAB).

So, now you know how and why the water collects in your dehumidifier, make sure you also understand what size dehumidifier you need to help deal with the excess moisture in your home. And, while there are endless benefits to owning one of these devices, we explore the question of 'can you have too many dehumidifiers' to make sure you don't buy too many

Do dehumidifiers dry clothes? This is a really common question these days, with energy costs and household bills at the forefront of many people's minds.

Now that our outdoor washing lines are being packed away for winter, the most obvious way to get clothes dry fast is to turn to our trusty tumble dryers – but handy though they are, they can also be notoriously energy hungry.

This has led to a rise in people looking for alternative ways to dry wet clothes – and given that dehumidifier running costs are relatively low, using these appliances is a method that many people are considering. So, can this type of appliance be used for this purpose or should they be reserved for keeping condensation and damp at bay?

Do dehumidifiers dry clothes?

We have some good news here – dehumidifiers are not just for dealing with window condensation, you can use a dehumidifier to dry clothes too. Even better, this can be far cheaper than using your tumble dryer.

That said, some dehumidifiers are more effective at drying clothes than others so it is important to check out the various functions of the models you are interested in before buying.

Laura Bradbury, Head of eCommerce at Vonhaus says, "It’s a gentler and more energy-efficient option that also helps reduce condensation and damp in your home.”

How do dehumidifiers dry clothes?

So, how do dehumidifiers dry clothes exactly? Viktor Velikov, Director at Elserve, explains, "As clothes dry, they release moisture, which the dehumidifier captures and condenses into liquid form. This process removes humidity from the space, speeding up drying while also helping to prevent damp and mould from developing."

You should look for a dehumidifier with a laundry mode or clothes drying mode. On these settings, a dehumidifier will filter out moisture and blow it back out, running on the highest fan speed and lowering the humidity to normal humidity levels.

In order to get the most out of the dehumidifier on this setting, it is wise to close the door of the room and place the unit close to where the clothes are hanging.

Is a dehumidifier cheaper to run than a tumble dryer?

In short, yes, dehumidifier running costs are less than those for tumble dryers. That said, they can take much longer to dry clothes.

When looking at dehumidifier running costs, you need to look at the model's power rating and how much you pay for electricity per kWh. From October 2025, the national average price of electricity is 26.35p per kWh, according to Ofgem.

Dehumidifiers are rated in Watts (W) – the higher the power, the more energy it uses. So, a model with a power consumption of 151 watts would cost 4p per hour to run – based on the calculation 0.151kWh x 26.35p = 4p per hour.

A model with a wattage of 400W would cost 10.5p per hour.

The cost of running a tumble dryer is usually calculated per cycle – and an average cycle tends to take around an hour. Vented and condenser tumble dryers cost around £1.70 - £1.80 per cycle (heat pump tumble dryers are far cheaper to run) which means that if you use yours twice a week, you will currently be facing bills of around £176 to £187 a year.

How long does a dehumidifier take to dry clothes?

It takes between four and six hours to dry laundry with a dehumidifier, according to Laura Bradbury. However, it will depend on the amount of laundry and the humidity levels in your home.

Pros and cons of using a dehumidifier to dry clothes

Pros:

• Reduced condensation: At the same time as drying your clothes, the moisture produced will be being dealt with by the dehumidifier.
• Additional heating: The heat produced by desiccant dehumidifiers can be used to warm up your home, meaning less reliance on other heating methods.
• Less risk of damp or mould: Wet clothes hanging around can result in damp patches on walls – something that a dehumidifier will prevent.

Cons:

• It takes a long time: While it is certainly much cheaper to use a dehumidifier to dry clothes than it is to run the tumble dryer, it will take longer to get the same results – perhaps up to five or more hours on average. Factor this when looking at running costs.

Where should you position a dehumidifier to dry clothes?

To achieve the best results, Laura Bradbury recommends placing your dehumidifier and laundry in an enclosed space, such as a spare bedroom or utility room. Make sure the device is a few feet away from the clothes, and keep your windows and doors closed. While it might seem like a logical position, you should never put your dehumidifier in the bathroom.

If you don’t mind waiting a little longer for your clothes to dry, switching to the best dehumidifier can be a great way to save money – especially since they offer so many other benefits at the same time.

Still unsure about making the switch? We’ve compared the pros and cons of using a dehumidifier vs a tumble dryer to help you choose the right option for your home.

A drop in temperature can often mean the advent of condensation inside your home. And whether it's moisture on your windows or walls, it's usually time to accept that dehumidifier running costs are going to be adding to your energy bills.

But, how much do the best dehumidifiers cost to run and are there certain models that are cheaper, or ways of using them that can decrease your expenditure?

We've spoken to experts and crunched the numbers to give you a clearer idea of what you can expect from your dehumidifier running costs this autumn and winter.

Calculating dehumidifer running costs

There are many reasons why people choose to use dehumidifiers, particularly as the seasons change and it becomes colder and wetter outside. Not only can they eliminate the issues associated with hanging damp laundry around the house, such as damp, but they can also help to reduce the time it takes for your washing to get dry and help solve and prevent condensation.

So, how can you work out how much dehumidifier running costs are?

When calculating dehumidifier running costs, you need to look at the model's power rating and how much you pay for electricity per kWh. From 1 October – 31 December 2025, following the energy price guarantee, the national average price of electricity will be 26.35/kWh.

Dehumidifiers are rated in Watts (W) and this is the amount of power the they use. The higher the power, the more energy it uses.

This means a model such as the Dreo Dehumidifier 512S from Amazon, which uses 0.4kWh would cost as follows: 0.4kWh x 26.35p = 10.54p per hour.

As another example, the Meaco Dry Arete One 10L Dehumidifier & Air Purifier from Amazon, has a power consumption of 151 watts at 20°C and 60% relative humidity.

To establish how much it would cost to run, you would use the following calculation: 0.151kWh x 34p = 5p per hour.

Which dehumidifiers are cheapest to run?

There are several factors that affect how much a dehumidifier costs to run, including the type you opt for.

"Dehumidifiers generally come in two main types: compressor and desiccant," explains Olivia Xu, chief marketing officer at DREO. "Compressor models will deliver the best balance of efficiency and cost savings.

"Depending on their size, they can remove up to 20 L of moisture per day and reduce relative humidity quickly. They are also highly energy-efficient," she adds. Although the downside is you can expect to may more upfront for a compressor dehumidifier vs a dessicant model.

"Desiccant dehumidifiers on the other hand are the cheapest to purchase and can operate in cold environments," she continues, "but they have low efficiency, deliver the weakest dehumidification performance, and require higher maintenance and often lack smart features."

However, things are not always so straightforward. Bear in mind that desiccant dehumidifiers have benefits that compressor models don't – mainly that they can heat the room they are in as well as getting rid of excess moisture in the air.

In fact, the air they expel can be as much as 12°C warmer that the air it took in. Compressor units, on the other hand, barely warm the air at all. Using a desiccant unit can help with drying clothes quicker and mean you will need to heat the room less – so the extra costs could be seen to be worthwhile.

That said, with many compressor dehumidifiers having a laundry drying mode, when testing the De'longhi DEX212F 12L dehumidifer to dry my laundry, I personally found that that the dehumidifier pushes out warm air as it dries and subsequently did heat the space it was located in.

How to cut dehumidifier running costs

One of the main ways to ensure you are not paying too much for your dehumidifier running costs will be to choose the right one for your home and needs. This will also mean that you are not paying for a dehumidifier that isn't running as efficiently as it should be.

Firstly, think about the type of space you are purchasing the dehumidifier for. As mentioned before, certain types of dehumidifier are better for cold spaces, such as conservatories and garages, while others work best in warm rooms, such as bedrooms or living rooms.

"Compressor units run on a refrigerant. So just like a fridge if they get too cold, they go into defrost – you don’t want to spend your money on a machine that will defrost more then it will dehumidify," says Chris Michael, founder and managing director of Meaco.

"If it is going to be used in a space where the temperature goes below 15 degrees, a desiccant variety will be better. Desiccant models have an internal heating system, so they can function far better in colder temperatures."

Next you need to think about the capacity you will need. "The more people there are, the more washing, showering, cooking, talking and breathing there is. This will add to the humidity in the atmosphere and in the property," explains Chris Michael. "With two or three people in a home, the 10L or 12L models would be suitable. In a larger family, the 12L or 20L will be needed."

Choosing a low cost dehumidifier

There are a number of functions on dehumidifier designed specifically for saving energy, so if you are in the market for a new model, it makes sense to look out for the following:

• Smart humidistats: On a dehumidifier, the humidistat works in a similar way to a thermostat on a heating system – apart from it monitors the humidity level in a room as opposed to the temperature. The more advanced models allow you to set the desired humidity level and will then maintain that, either going into sleep mode once it is reached to conserve energy, or switching off altogether
• Motorised louvres: These are designed to direct the newly dried warm air through a wide angle set of louvres in order to speed up the drying time of laundry. The most advanced models will detect when the humidity levels in the room drop and reduce power consumption accordingly. It is also worth noting that drying laundry this way should save on the cost of running a tumble dryer
• Adjustable speed: It is worth paying a little more for a dehumidifier with more than one speed option – you won't always need it running at full pelt. Some of the most advanced models will adjust the running speed for you

"For optimal efficiency, running a dehumidifier in auto mode, which automatically maintains the ideal humidity level for any space and keeps conditions comfortable without manual adjustments, is a great idea," suggests Olivia Xu .

Choosing a model with an app can also be an advantage adds Olivia. For example, "the companion DREO app adds powerful smart controls, including cleaning reminders, real-time humidity graphs, a timer, customisable schedules (working hours, modes, and speed), and smart voice integration with Google Home or Alexa," she explains.

This can make it easier to manage when and how often you are using it as you can fine-tune the scheduling and settings from anywhere.

Finally, in order to get the very most out of your dehumidifier, be sure to close windows and doors when it is running, clean or change the filters regularly and make sure your bathroom and kitchen extractors are working properly.
