Condensation on the windows every morning, a musty smell in the bedroom, black mould creeping into the corners of the bathroom: damp is one of the most common winter problems in UK homes. A good dehumidifier pulls that extra moisture out of the air, which helps stop condensation, damp and mould before they take hold.

Compressor vs Desiccant Dehumidifier: Which Do You Need?

There are two main types of dehumidifier, and picking the right one matters.

• Compressor (refrigerant) dehumidifiers work best in heated rooms, like a living room or bedroom with the heating on. They're usually the cheapest to run in a warm home.
• Desiccant dehumidifiers keep working well in cold spaces, like an unheated bedroom, a garage, a conservatory or a caravan. They also give off a little warmth while they run.

Simple rule: if the room is heated, choose a compressor model. If the room is cold, choose a desiccant model.

The Best Dehumidifiers for Damp and Mould

1. Pro Breeze 12L Low Energy Dehumidifier: Best Budget Pick

An affordable compressor dehumidifier that removes up to 12 litres of moisture a day. It has an automatic humidity sensor and display, a sleep mode for bedrooms, and a 24-hour timer. A great choice for a flat or a few damp rooms.

2. Pro Breeze OmniDry 20L Dehumidifier: Best for Bigger Homes

Need more power? The OmniDry removes up to 20 litres a day and has a laundry mode for drying clothes indoors, which is a big help when washing has to dry inside all winter.

3. Meaco Arete One 10L: Best Dehumidifier and Air Purifier in One

Meaco is one of the best-known dehumidifier brands in the UK. The Arete One 10L is also a HEPA air purifier, so it removes moisture and filters dust and allergens at the same time. It's made for smaller houses and flats.

4. Meaco DD8L Zambezi: Best Desiccant Dehumidifier for Cold Rooms

The DD8L is a desiccant dehumidifier designed for unheated rooms, including spaces below 10°C where compressor models struggle. Choose this one for a cold bedroom, garage, conservatory or outbuilding. It also has an ioniser.

5. Duux Bora Smart 20L: Best Smart Dehumidifier

A stylish, modern dehumidifier with a clothes drying mode that you can control from your phone. It's Quiet Mark certified, so it's a good pick for living spaces and bedrooms.

6. Pro Breeze 1000ml Mini Dehumidifier: Best for a Bathroom or Wardrobe

A small, quiet dehumidifier for one small space: a bathroom, a wardrobe, a cupboard or a small bedroom. It won't fix damp in a whole house, but it's great for one problem spot.

Cheap Extras That Help With Damp and Condensation

Kärcher WV 1 Window Vacuum

If your windows are dripping with condensation every morning, a window vacuum sucks the water off in seconds. Clearing it daily stops it from soaking into the window frames and sills, where mould starts.

UniBond Aero 360 Refill Tabs

Moisture absorbers are perfect for cupboards, wardrobes and small rooms. These refill tabs fit the UniBond Aero 360 unit. Tip: choose Subscribe & Save on Amazon to save a little extra on refills you'll use all winter.

Digital Hygrometer (2-Pack)

A hygrometer shows the humidity level in a room, so you know whether you have a damp problem and whether your dehumidifier is working. This 2-pack also shows the temperature.

HG Mould Remover Spray

A dehumidifier helps stop new mould, but it won't remove mould that's already there. This mould remover spray tackles black mould and mildew on walls, tiles and grout.

Window Condensation Absorber Strips

Stick these along the bottom of your windows to catch condensation drips before they reach the sill.

How to Stop Damp and Mould in Winter

• Keep humidity between 40% and 60%. A hygrometer tells you where you are.
• Run a dehumidifier in the dampest rooms, especially bedrooms and rooms where you dry washing.
• Ventilate. Open windows for a few minutes a day and use extractor fans when cooking and showering.
• Wipe condensation off windows every morning.
• Keep furniture slightly away from outside walls so air can move behind it.

If damp keeps coming back, or there's a lot of mould, the cause could be a leak or a building problem. In that case, speak to your landlord or a damp specialist.

Dehumidifier FAQs

What size dehumidifier do I need for a UK house?
A 10–12 litre dehumidifier suits most flats and small homes. For a larger house, or if you dry washing indoors, choose a 20 litre model.

What is the best dehumidifier for black mould?
For a heated home, a compressor dehumidifier like the Pro Breeze 12L or OmniDry 20L. For cold rooms, a desiccant model like the Meaco DD8L. Remove existing mould with a mould spray first, then use the dehumidifier to stop it coming back.

Which dehumidifier is best for a cold room or garage?
A desiccant dehumidifier. Compressor models lose efficiency in cold rooms, while desiccant models like the Meaco DD8L keep working.

Can a dehumidifier dry clothes indoors?
Yes. Models with a laundry or clothes drying mode, like the Pro Breeze OmniDry 20L and Duux Bora Smart, help washing dry faster indoors and stop the moisture from causing condensation.

Where should I put a dehumidifier?
In the room with the most condensation or damp, usually a bedroom, bathroom or the room where you dry clothes. Keep it away from walls and furniture so air can flow around it.

Do dehumidifiers help with condensation on windows?
Yes. Lowering the humidity in a room means less moisture settles on cold windows. A window vacuum is a quick fix for the condensation that's already there.

Will Dehumidifiers Be on Sale for Black Friday?

Dehumidifiers often drop in price during Amazon's Black Friday Week. Black Friday 2026 is on 27 November, so check the current price before you buy.
