Owning one of best bathroom extractor fans will make you wonder why you didn't invest in one sooner. 

Bathrooms are damp rooms, and a lot of humidity is produced when we take showers. Once the air cools, this trapped humidity turns into water and can encourage mould and fungus to grow, which is not good for our health and can cause problems such as skin irritation and allergies. 

The health benefits alone can make an extractor fan a key part your bathroom design. These machines suck out the moisture that builds up in your bathroom, quickly removing harsh odours and preventing mould growth, as well as staving off rusting and paint peeling.

It is not a legal requirement to own an extractor fan if your bathroom has an openable window, but buying a bathroom extractor fan is still a good idea - plus, they come in different shapes and size so you can find the right fit for your home

Take a look at the best bathroom extractor fans available now to prevent humidity building up in your bathroom.

Specifications

Installation: Walls and ceilings
Air extraction rate: Up to 96 m3/h / 26 l/s

Adjustable humidity sensor

Installation could be easier

The highly-stylish Envirovent SIL100T Silent Extractor Fan is our overall winner for many reasons. 

This is another low-noise machine, releasing just 26.5 dB at 3m noise output, which is achieved through the motors being mounted on silent elastic blocks.

It comes with an adjustable humidity sensor that lets you set the relative humidity level (between 60-90%), and this will turn the fan on when required to help prevent condensation. It will then continue to operate until the relative humidity level is achieved (it doesn't take long, circulating air at the rate of 96 m3/h), and will turn off when the moisture level drops below your set level. 

The run-on timer is another practical feature, which automatically calculates how long the fan should operate based on how long it has been running. The timer delay can be set manually for up to 30 minutes.

Humidistat isn't the most reliable

The Xpelair C4TS is one of the quietest bathroom extractor fans around. You can relax in the bathroom bother-free while it's doing its thing, and it also means any family in close proximity (such as sleeping children) won't be disturbed. 

It can be easily installed on a wall, ceiling or panel - it simply requires a 'twist and click' to secure the lock it into place. And during installation you can select from two motor speed settings - 15 litres per second (l/s) and 21 l/s, or 54 metres cubed per hour (m3/h) and 75 m3/h. The slower speed is very quiet, but takes a bit longer to demist your bathroom.

Plus, while looks aren't always everything, this is a beaut that will easily fit with most modern bathroom ideas. Sleek and smooth, the white finish will blend in with any type of bathroom decor. 

The timer can be adjusted between periods of 30 seconds and 30 minutes, and the fan comes with a two-year manufacturer's guarantee.

Rich with features and comes with a 3-year guarantee

Specifications

Noise level: 27dB
Installation: Walls and ceilings
Air extraction rate: Up to 75 m3/h / 21 l/s

Reasons to buy

+
Turning vane technology
+
Energy efficient
+
Backdraught shutter

Reasons to avoid

Can be noisy when turned off

While not as powerful or quiet as the top two fans on this list, Manrose's QF100T fan boasts performance-enhancing design credentials that make it a really excellent product.

One of these features is a turning vane system, which smoothly directs air in the duct and reduces resistance when there is a change of direction. This ultimately helps to deliver high output. 

A backdraught shutter is included too, which prevents air flowing in the wrong direction when the fan is turned off. This is a really energy-efficient design choice, with the motor consuming a maximum of 4.8W.

The fan is made from ABS thermoplastics so it's very durable - handy in busy bathrooms where it is likely to be knocked - and it comes with a three-year manufacturer's guarantee.

A tad noisy

It won't be winning any design awards, but if you're willing to overlook it's aesthetic quirks, the Blauberg UK Turbo-150 is a high-power extractor fan that offers good value for money.

This is an in-line fan (more on this below) which means it's specifically designed to fit in your ceiling when your bathroom is very far away from an external wall. It fits several different duct diameter sizes, so there should be something suitable for your home. 

It can be electrically wired directly into 240V mains power with a 50W motor, and has an efficient range of mixed flow extractor fans - it can reach an impressively high air flow rate of up to 560 m3/hour. It takes roughly 30 minutes to install, including the wiring.

Air extraction rate: Up to 80 m3/hr / 22 l/s

Not the most stylish

Centrifugal fans can generate more pressure than axial wall fans, and because they can extract down much longer duct runs it makes them a great choice for bathrooms which are much further away from an external wall. 

The versatile Solo Plus T from Vent-Axia is our top centrifugal fan pick for a few reasons. Firstly, it offers a choice of two boost motor speeds at installation - medium (17l/s) or high (22l/s) - and you can also select an optional constant trickle speed (9l/s) so there's always some flow through the room (even when no one is in there). You can revert back to your chosen setting via a pull cord, light switch or the humidity sensor.

It also comes with a 'delay' option, which means the fan won't kick in for around five minutes after the light is turned on. If you were to have a shower, for example, then it will continue to run for 20 minutes after the light is turned off to clear the humidity.

It can be mounted on a surface or installed flush, and the impeller allows for installations with longer duct runs using 100mm ducting. It comes with a two-year manufacturer's guarantee.
