If the damp and drizzly weather has left your home in desperate need of a quality dehumidifier, then look no further. We’ve just found one of our highest-scoring models in our latest group test.
Damp, condensation and mould can be a nightmare for homeowners when the rain arrives, leaving walls wet and windows steamy. But the constant downpours can be offset by using a good dehumidifier.
As well as looking at the latest dehumidifiers on test, we’ll run through how the two types of dehumidifier work and when it’s best to use one.

How do dehumidifiers work?
Dehumidifiers draw excess water from the air, helping to minimise condensation and damp, while also preventing mould growth.
You can get two different types:
- Refrigerant (or compressor) – the most common type of dehumidifier in the UK, refrigerants work by creating a cold surface. The condensation forms on the cold surface and then drips into a water tank.
- Desiccant – these types use an absorbent material to extract water from the air, which then heats up so the moisture drips into the tank. Designed to work better in lower temperatures than refrigerants, these make a good choice if you need a dehumidifier for an unheated garage, conservatory or basement. That said, we have found dehumidifiers of both types that work well in warm and colder conditions.

When should you use a dehumidifier?
Here’s a few scenarios when a dehumidifier can prove invaluable:
When your windows are covered in condensation – interior window condensation is caused by excessive moisture in the house. A dehumidifier will remove this, therefore reducing condensation and the risk of damp forming.
When a room smells musky – this is normally a sign of mould spores or damp conditions.
When you find dark spots on your ceiling – this is the start of mould or mildew. You’ll typically find them on your walls and ceilings, and the areas around your toilet and shower.
When you keep getting colds – using a dehumidifier properly can help with minor respiratory problems by reducing dampness and mould. Humidity density should be between approximately 30-50% for optimum health within the home and a good dehumidifier can help regulate this.
When the warmer weather arrives – dehumidifiers are not just for the colder months. You can use one when the air in your home feels humid and sticky and you don’t want to let more warm air in through open windows.
When you’ve just showered or you’re drying clothes – both of these will increase the moisture in the air dramatically, making it one of the best times to turn on your dehumidifier. Some models come with a laundry drying setting – but don’t pay extra for this. You’ll get the same effect by turning up the dehumidifier to full power.
Here’s our top tips on getting the most out of your dehumidifier.
