The best dehumidifier under £100 UK shoppers can buy, for most people, is the Pro Breeze 12L compressor dehumidifier. It pulls up to 12 litres of water a day from the air (maker claim), has a laundry drying mode, a humidity setting that switches it off when the room is dry enough, and a 2L tank. It was just under £100 when we checked. Want to spend less? The Ometa Pure 12L was about £70. Need it quiet for a bedroom? The slim Duronic 12L claims 36dB.
Under £100 you can still buy a proper compressor dehumidifier, not just a tiny "mini" one. Compressor models work best in heated rooms, which suits most UK bedrooms, living rooms and flats. They help with wet windows, musty smells and washing drying indoors, but they will not fix a leak or rising damp. For premium and desiccant picks, see our best dehumidifiers UK hub. Buying for a bedroom? See the best dehumidifier for damp bedroom UK guide. Only need to dry a wardrobe or cupboard? A moisture absorber costs far less. We have not tested these ourselves.

Power is the listing figure. On auto or humidity mode the compressor switches off once the room reaches your set humidity, so real use is often lower. Your own rate depends on your tariff and region.

Dehumidifier Safety
Stand the dehumidifier upright on a flat floor, and if it has been lying down, leave it upright for the time the manual says before switching on (KNKA says 24 hours). Keep air vents clear. Empty the tank or use a drain hose so water cannot spill. Do not run it in a sealed room with a fuel-burning heater. A dehumidifier helps manage moisture but will not fix leaks, rising damp or serious mould. This is general advice, not building or medical advice.
Research Methodology
How We Chose These Products
We have not tested these ourselves. This is desk research focused on compressor dehumidifiers under £100 on Amazon UK.
We searched Amazon UK for budget compressor dehumidifiers and checked each listing live on 7 October 2026 for price and stock, keeping only models under £100 that day. We left out tiny "mini" dehumidifiers that collect well under a litre a day, because they are not a fair comparison. We read verified UK buyer reviews and compared maker specs: daily extraction claim, tank size, drain hose, laundry and sleep modes, noise claim and power. We never make up prices or test results.

- •Star ratings and review counts change over time

Frequently Asked Questions
Common questions about dehumidifiers under £100
For most people we pick the Pro Breeze 12L compressor dehumidifier, because it has a laundry mode, humidity control and a 2L tank for just under £100. For the lowest price, choose the Ometa Pure 12L. For a quiet bedroom, choose the slim Duronic 12L.
A budget compressor dehumidifier that removes 10 to 12 litres a day can make a real difference to condensation and musty rooms. Be wary of tiny "mini" dehumidifiers under about £50. They often collect less than a litre a day and suit a cupboard, not a room.
A 10L model suits a small bedroom or box room. A 12L model suits most bedrooms, living rooms and small flats. For large rooms, very damp homes or lots of indoor washing, look at bigger models in our main dehumidifier guide. Not sure? Our dehumidifier size calculator suggests a size in a few clicks.
Our five picks list about 187W to 300W. The running-cost table on this page works out a rough cost at the current UK price cap for 6 hours a day. On humidity mode they switch off once the room is dry enough, so real use is often lower.
Compressor dehumidifiers, like all five here, work best in heated rooms and slow down in cold ones. Auto defrost helps. For an unheated garage or conservatory, a desiccant dehumidifier is better, but most cost more than £100. See our main dehumidifier guide.
Yes. Put it in the same room as the washing with the door shut. The Pro Breeze 12L and Shinco 10L have laundry modes. For more laundry-focused picks, see our dehumidifier for drying clothes guide.
Makers measure them in warm, very humid conditions, often around 30°C to 35°C and 80% to 90% humidity. In a normal UK room a dehumidifier will remove less than the headline figure. Use the figures to compare models, not as a promise.
Compressor dehumidifiers hum like a fridge. Duronic claims 36dB and Pro Breeze claims under 42dB, but we have not measured them. Sleep modes on the Ometa and KNKA turn the fan down or the lights off for bedrooms.
Put it in the dampest room with doors and windows closed, at least a little way from walls and curtains so air can flow. Keep it away from heaters, and run it next to washing if you are drying clothes.
It helps stop mould coming back by keeping the air drier, but it will not remove mould that is already there or fix a leak or rising damp. Clean existing mould safely and get serious damp checked. For cupboards, a moisture absorber is a cheap extra.
Ready to tackle damp without spending £100?
