How Do Extractor Fans Work


An extractor fan is usually fitted to a hole in an outside wall, or window and it extracts damp, stale air from the room. This is transferred to the outside and replaced in the room via another opening (usually an open window). Extractor fans have a simple design, a fan is connected to a motor powered by electricity. As the fan spins it draws air from the room and expels it outside via a hole in the wall/window/ceiling.

What Are The Benefits Of An Extractor Fan

The benefits of an extractor fan are not all as obvious as you might think, here in no particular order are the benefits of having an extractor fan installed.

Keeping Mould In Check

A build-up of black mould is a sure sign your home is too damp. Many homes suffer from this problem and in most cases, it can be solved by having an adequately powered extractor fan. Mould thrives in warm, moist conditions so the kitchen or bathroom are the usual places where mould is most evident.

There are many products that remove mould, but to keep it away you need to deal with the problem of how it grows. By installing the right extractor fan, you will remove moist air, steam, and humidity. As the room dries out you will notice a marked improvement in the amount of growth of mildew and mould.

Less Steam, fumes, And Smells

It’s not just steam and moist air that is removed by an extractor fan, it’s also any fumes and smells. Particularly handy for kitchens but also very useful for bathrooms too.

Improved Air Quality

Less smells, less moisture, and fresh air. These will all be achieved by installing the correct extractor fan.

Keep Homes Cooler In Summer

Extractor fans can be used in the Summer to expel hot air from the home, although this is not as good as air conditioning, it can make a difference to the overall temperature of the home.


If mould and mildew are allowed to spread unchecked, it will damage your possessions. Which will need to be replaced, costing money. Plus if the problem is not dealt with correctly, it will be a continuous process.

A Comfortable Environment

As the air quality improves in your home and feels fresher, you will notice your overall outlook will be more positive. A comfortable environment makes for a peaceful mind.

Removal Of Harmful Gases And Pollutants

Especially with kitchen fans, every time you light a gas cooker, gas is released into the room. If there is a smoker in the home, extractor fans will help to remove the pollutants associated with smoking.

Protecting Walls And Furniture

Again cigarette smoke contains harmful tar and other chemicals that over time, build up on walls and furniture fabric. Extractor fans will remove some of these chemicals and preserve your fabrics and walls, giving you longer between redecorating and replacing furniture.

Law Abiding

Since 2018 in the UK it is law that an adequate extractor fan is installed in every home. Most homes have an extractor fan but is it powerful enough?

What Are The Disadvantages Of An Extractor Fan

The main disadvantage of an extractor fan is it is not powerful enough to cope with the condensation and steam that build up in the average bathroom. This is of course easily remedied by installing the correct fan.

Another disadvantage is that to work properly, extractor fans need ventilation, usually in the form of an open window. This is fine in Summer but in the middle of Winter, it’s pretty uncomfortable.

Most extractor fans are wired into the light switch, this means every time the bathroom light is turned on, the extractor fan comes on whether it’s needed or not. Of course, the better quality extractor fans have humidity sensors that only cut in when excessive moisture is detected.

Extractor Fan Buyers Guide

Here are the main points to consider before purchasing an extractor fan, in no particular order:

Noise Levels

Sadly all extractor fans become noisy over time. This is due to the motor bearing wearing down. Even cheap extractor fans are quiet straight out of the box, but these will get noisy quicker. Most decent extractor fans will last at least 2 years before they get too noisy to bear.

At some point though you will need to replace your existing extractor fan.


The higher the power, the better the extractor fan works. Under UK law extractor fans have to extract 17 litres per second and most range between 17-25 litres per second.

Method Of Fixing 

Most extractor fans can be reinstalled by the average DIYer, obviously, if you’re not comfortable messing with electrics, or if it’s a first-time installation you should employ a professional. If you are going to fit one yourself, consider how much effort will be needed to reinstall it.

Some fittings are easier than others. Most makes and models show their specifications online.

Run On Timer

This is almost like a delay switch in reverse, what happens is you turn on the light, and the fan clicks on. When you turn off the light the fan stays on for a preset time. Not all units have this feature, and it’s well worth having as it helps to remove extra moisture.


A humidistat (hygrostat) is used to measure the levels of moisture in the air, if fitted to an extractor fan, it allows the fan to cut in as soon as moisture levels rise. It will also cut the extractor fan out when humidity levels fall below the desired levels.


Where is the most effective position to situate your extractor fan? The choices are window fans, wall fans, and ceiling fans. It’s probably best to get expert advice on where to place an extractor fan for maximum moisture control.

How Much Is An Extractor Fan

Bathroom extractor fans start at around £14 for a cheap and cheerful model, you can expect these cheap models to be noisier than some of the more expensive models. Fairly decent models can be purchased for around £50, but the most expensive models can be well over £700.

It’s not just the cost of the unit though, if you don’t feel confident enough to replace your extractor fan yourself, you’ll need the services of an electrician. A fully qualified electrician will charge on average between £150-£300 to install an extractor fan.
