What does a dehumidifier do?
Humidity is more than something you experience just before a thunderstorm, at the height of summer or while you’re on holiday in the tropics.
UK homes in the winter can suffer from extra water in the air from drying our clothes indoors rather than on a line outside. Alternatively, some homes are generally more prone to damp or mould in the winter months, so a dehumidifier is a great investment if you need to reduce the water in a building.

Why should you buy a dehumidifier?
If there’s an excess of humidity in your home, then you risk having water stains on the walls, mould on the ceilings or condensation on the windows - all of which can lead to problems.
Typical problems include creaking floorboards, warped wood, peeling paint and insects such as silverfish or spiders coming in. The additional moisture in the air can also have a negative impact on your health.
So, how do dehumidifiers work?
Dehumidifiers pull water from the air, and the best ones do it quickly and at room temperature without using too much energy. There are two types of dehumidifier to choose between:
- Compressor - a dehumidifier which works better in hotter temperatures and higher humidity – which makes it a good choice for most UK homes. These types tend to draw air in over a filter and then direct it over cold coils, which makes the water in the air condense and fall into a water tank
- Desiccant – these dehumidifiers work best in colder environments, like a garage or conservatory. They work by using an absorbent material to draw the moisture from the air, which is then heated to pass the water into the condenser.
There are also various sizes to choose from, based on how much water they can hold. So, whichever you go for will essentially depend on how much space you have.
Bear in mind that the amount a dehumidifier can extract per day is greater than the size of their tank, so you’ll need to think about how you empty the tank, too.
What else do you need to think about before you buy?
- If you don’t fancy emptying the water tank regularly, then look for a continuous drain facility – you can connect a hose to drain the water away
- Consider whether the dehumidifier has a humidistat – it turns itself on and off, maintaining the humidity you’ve chosen
- An alternative to the humidistat is a timer. You can use this to set the unit to run over a set time and save electricity
- How easy it is to move from room to room – some have wheels, so you don’t have to lift!
- Check how noisy the unit is – you don’t want to be disturbed while it works its magic
