Best Dehumidifier for Home in 2026: 10 Ranked by Extraction and Running Cost

With 5,662 ratings this has more customer feedback behind it than every other unit on this page put together, and it holds the Which? Best Buy award for dehumidifiers in 2025. Which? described it as quiet enough that it should not bother you if you are working at home with it running nearby — which matters more than it sounds, because a dehumidifier is not something you switch on for an hour.

The numbers behind that are solid. It extracts 12 litres a day into a 1.8L tank, runs at under 38dB, and Pro Breeze puts the running cost as low as 7p per hour. Over a British winter that is the figure that decides whether you leave it on. The humidity sensor lets you set a target between 30% and 80% and shuts the unit off once it gets there, so it is not running pointlessly at 3am.

Three operating modes cover auto, continuous and sleep, there is a 24-hour timer, and a removable hose gives continuous drainage if you would rather not empty the tank at all. Four wheels are included. The one thing to weigh is capacity: 12 litres a day suits one damp room or a small flat. If you are fighting condensation across a whole house or drying laundry indoors regularly, the 20L Pro Breeze at number three is the better fit.

If the machine is going to run through a British winter, this is the one that costs least to do it. Devola quotes 5p per hour based on 24p/kWh, the lowest published figure on this list, and at 36dB it is also the quietest at full speed. Against the Pro Breeze at number one, those 2p an hour work out at roughly £15 over a winter of heavy use.

It carries two independent endorsements rather than one: Which? named it a Great Value dehumidifier in November 2025, and it is approved by the Good Housekeeping Institute for 2026. Extraction is 12 litres a day into a 2L tank, with a drainage hose included for continuous running, four castors and a carry handle. It weighs 10.5kg and measures 47 x 25.5 x 22cm.

The specification that sets it apart is temperature. Devola states it extracts effectively down to 5°C, which most compressor dehumidifiers struggle with — and an unheated garage, conservatory or hallway in January is exactly where damp forms. Worth knowing about the listing itself: its spec table gives the floor area as 1 square foot, which is obviously wrong for a 12L machine and a good illustration of why that field is worth ignoring.

This is the step up when one room is not the problem. It extracts 20 litres a day and, crucially, pairs that with a 5.5L tank — the second largest here — so the extra capacity does not turn into emptying it three times a day. Pro Breeze rates it for rooms up to 325 square feet.

It is the second Which? Best Buy on this list, and the citation is worth reading: Which? noted that unlike many refrigerant models it works reasonably well in colder rooms too. That is the standard weakness of compressor dehumidifiers, and it is precisely the condition — a cold, unheated room in winter — where damp actually appears.

Five operating modes cover strong, natural, ventilation, continuous and laundry, and the laundry mode is claimed to extract up to 600% more water than the previous generation. A carbon filter tackles musty odours alongside a washable dust filter, and an auto-swing louvre rotates 120 degrees to circulate air rather than drying one corner of the room. There is a child lock and a sleep mode that kills the lights. At £161.49 it is the third most expensive here, but per litre of extraction it is better value than the 12L units above it.

Almost every dehumidifier sold is 12L or 20L, which forces a choice between not quite enough and more than you need. The KNKA sits at 16 litres a day, and for a two-bedroom flat with condensation on the windows that is often exactly right.

With 1,980 ratings it has the third largest sample on this list, behind only the two Pro Breeze units. It draws a maximum of 260W and KNKA puts the running cost at £0.06 per hour, which sits between the Devola's 5p and the Pro Breeze's 7p. The 3L tank is proportionate to the extraction, and KNKA rates it for 35 square metres, roughly 375 square feet.

Physically it is unusual: at 48 x 28 x 20cm it is wide and shallow rather than tall, and KNKA points out it takes up less floor space than a sheet of A4. A removable soft handle makes it easier to carry between rooms than the wheeled units here. Sleep mode turns off all the indicator lights, which matters in a bedroom. Note one small inconsistency in the listing: the title mentions a 3.3L tank while the spec table says 3 litres.

Honeywell is the most recognisable name in this ranking, and the unit is approved by the Good Housekeeping Institute for 2025. It matches the Devola on running cost at 5p per hour, calculated at 25p/kWh, and its 2.5L tank is larger than both 12L units above it, so it needs emptying less often.

Four operating modes include a one-click laundry drying mode that Honeywell positions as a cheaper alternative to a tumble dryer, using higher fan speed for airflow. There is a 24-hour timer, a filter cleaning alert, auto defrost and auto restart, plus a carry handle and four castors. Honeywell suggests it suits a two to three bedroom house or flat.

Two things keep it at number five. It is the loudest unit here by its own figures: 40dB normally, rising to 42.5dB in laundry mode, against 36dB for the Devola and under 38dB for the Pro Breeze. In a bedroom that gap is audible. And at £159.50 it is the most expensive 12L machine on this list, £44.76 more than the Pro Breeze that carries a stronger award and seven times the reviews. Its spec table also lists the floor area as 1.5 square feet, another example of that field being unusable.

If you need 20 litres of extraction and £161 for the Pro Breeze is more than you want to spend, this does the same daily volume for £21.50 less. The 4.5L tank is only a litre smaller, it covers the same 325 square feet, and its 4.6 average is the joint highest rating on this list.

The feature worth having is the colour-coded humidity indicator. Rather than making you interpret a percentage, the LED shows blue below 45%, green in the optimal 45-65% band and red above 65%. For anyone who is not going to learn what a healthy humidity level is, that turns the machine into something you can actually act on. The target humidity is adjustable from 30% to 80%.

Three modes cover auto, continuous laundry and sleep, with sleep running at under 41dB. Two fan speeds, a 24-hour timer, auto defrost to stop collected water freezing, a removable washable filter, 360-degree wheels and a child lock round it out. The reservation is evidence: 444 ratings is respectable but a fraction of the Pro Breeze units, and there is no independent award behind it.

The endorsement on this one is the strongest in the ranking. PureMate quotes Which? directly: this is the highest-scoring dehumidifier they have tested, and if you want a fantastic refrigerant dehumidifier, look no further. That is a stronger claim than a Best Buy badge, which several units here also hold.

The hardware supports it. A 6.5L tank is the joint largest on this page, so at 20 litres a day you are emptying it roughly once every eight hours rather than constantly, and continuous drainage is available if you would rather never touch it. PureMate rates it for 30 square metres. The humidity sensor is paired with both an LED readout and a three-light indicator system, and four castors clip on or off depending on whether you want it to roll.

Two things place it at seven rather than higher. At £169.99 it is the most expensive unit in this ranking, £8.50 above the Pro Breeze 20L that holds a Which? Best Buy and has ten times the customer feedback. And with 259 ratings its own sample is among the smallest here, so the Which? verdict is doing most of the work. If you trust Which? over crowd data, move it up your own list.

At £85.48 this is the cheapest dehumidifier in the ranking, £29.26 below the Pro Breeze at number one, and with 675 ratings it is better evidenced than several units costing twice as much. For a single damp bedroom on a tight budget it is a sensible entry point.

It extracts 12 litres a day and runs at under 36dB, matching the Devola as the quietest here, with a night mode on top. Three modes include a dedicated laundry drying setting, there are three fan speeds rather than the two most units here offer, and it moves 108m³ of air per hour. Castors and hidden side handles make it easy to shift between rooms.

The compromise is the tank. At 1.6 litres it is the smallest on this list, which means that at full extraction you would be emptying it roughly seven times a day — so in practice this is a unit you set up with the continuous drainage hose near a drain, not one you carry around. Its bullets say it covers 15m², while its spec table claims 2,000 square feet, which is about 186m². The bullets are the believable figure, and the gap between the two is a good reason to treat that spec field as noise.

On the headline figure this is the best value on the page: 25 litres a day is the highest extraction in the ranking, and £119.98 is below the price of most 20L units here. It uses a brushless DC inverter motor and a high-efficiency piston compressor, which is more advanced than the fixed-speed compressors in the cheaper units, and AEOCKY rates it for 50 square metres.

The problem is the pairing. A 25L/day machine with a 1.9L tank would need emptying roughly thirteen times a day if it ever hit its rated extraction. Compare that with the Pro Breeze 20L, which pairs slightly less capacity with a 5.5L tank, or the PureMate at 6.5L. Continuous drainage solves it, but only if you have somewhere to run the hose — otherwise the extraction figure is theoretical.

Two smaller points. The castor wheels are not pre-installed, which AEOCKY frames as flexibility but does mean assembly. And at 11.2kg it is the heaviest unit here despite the compact 26.7 x 20.4 x 43.2cm frame. With 247 ratings the evidence base is the second smallest on this list. Buy it if you can plumb it to a drain; skip it if you cannot.
