The best dehumidifiers, compared.
Top pick: CoamoTrail 2.2L mini Best value: ARIBIO 12L/day – Best value on a different ASIN, the ARIBIO 12L/day at about £129.99. Updated 20 October 2026.
A dehumidifier for a UK home collects water from room air so condensation and musty damp are less likely while it runs. People buy one because windows stream, washing will not dry, or mould has appeared. Judge it on extraction at a realistic temperature, a tank or hose you can live with, a humidistat that stops, and a BS 1363 plug. Compressor machines around 8–12 litres/day suit a bedroom or small flat; thermoelectric minis collect a few hundred millilitres in a warm test and will not dry a whole home. A machine does not repair a leak, rising damp, or a missing extractor, and it is not medical treatment. Renters with wet windows need a compressor sized to the room, and still report leaks and broken extractors. Households drying washing indoors want a laundry mode, a shut door, and an airer beside the unit. Cold spare rooms, basements, and unheated caravans are a poor match for a mini or a small compressor bought on stars alone. Heated room and condensation or indoor laundry: compressor. The checks before you buy are in the [Dehumidifier buying guide](/hub/cooling/dehumidifier/sub/dehumidifier-buying-guide).

Question 1 of 2
What do you need it to do?
The CoamoTrail HY25 claims up to 450 ml a day at 30°C and 80% relative humidity, into a 2.2 litre tank, at 22.5 W and £59.99. The listing writes the test point as 86°F. amazon.co.uk shows 5.0 from 50 reviews. UK comments that go beyond one line mention a quiet bedroom, sleep mode, fewer emptying trips because of the large tank, and use beside a clothes airer. Many of the 50 reviews are generic one-liners, and the saved listing also mixes in a non-UK review, so the 5.0 is a weak guide. The box list says a charging cable, which is an odd phrase for a mains unit. No IP rating is stated.
Pros
Cons
Best for: You want a quiet mini with a large tank for a bedroom, and you will not treat 5.0 from 50 short reviews as a test.
Less suitable: You need litres a day or a review file with specific complaints you can weigh.
Specifications
Common questions
Is 2.2 litres the daily extraction?
No. 2.2 litres is the tank. The daily claim is up to 450 ml at 86°F and 80% relative humidity.
What happens when the tank is full?
The listing says a full-water icon, a red light for 3 seconds, then automatic shut-off.
Does sleep mode change the power?
The listing says sleep mode turns the lights off and halves the power, with noise claimed under 30 dB.
The Devola DV8L is a compact compressor at £99.99 and 160 W, with laundry, auto and sleep modes, a 1.7 litre tank and a drainage tube. amazon.co.uk shows 5.0 from 7 reviews. In that small sample, one garden office dropped from 65% to 57% relative humidity in about 30 minutes, and owners also used it beside indoor washing. The water tray is slightly tricky to open and hard to clean. The title says 8 litres a day and another listing field says 12 litres a day, and the room-size field says 1 square foot, which is not a usable figure. Seven reviews are not enough to treat the 5.0 as settled. The Good Housekeeping line on the listing was not checked independently.
Pros
Cons
Best for: You want a compact compressor with a hose under £100 and you can accept that the daily rate is printed twice.
Less suitable: You need a settled extraction figure or a review sample larger than seven notes.
Specifications
Common questions
Is the extraction 8 or 12 litres a day?
The title and capacity field say 8 litres/day. Another field says 12 litres/day. Both are on the listing, so neither figure is cleaned up here.
Does it include a hose?
Yes. Included components are the dehumidifier, a drainage tube and a manual, plus a 1.7 litre tank.
How solid is the 5.0 score?
It is from 7 reviews. One of them says the water tray is fiddly to clean. That is a small sample.
The TEYIAN Dh-2 lists up to 660 ml in 24 hours at 30°C and 80% relative humidity, with a tank given as both 1800 ml and 1600 ml, at £34.99. amazon.co.uk shows 5.0 from only 3 reviews, which is too small a sample to treat as stable. Those three notes are short and positive: plug in, a tank that lasted the day, and faster drying beside an indoor airer. The specification table says 9 W, far below other semiconductor minis in this set, and it also claims 40 m², which does not sit with a 660 ml daily rate. Quiet mode is claimed at 32 dB. There is no repeated complaint in three reviews, and there is also no evidence yet of how it behaves after a winter.
Pros
Cons
Best for: You are curious about a cheap semiconductor mini and you will not treat three reviews or the 9 W line as settled.
Less suitable: You need a known running wattage or evidence past the first week. This file cannot give you either.
Specifications
Common questions
How much water does the listing claim per day?
Up to 660 ml in 24 hours at 30°C and 80% relative humidity, into a tank listed as 1800 ml or 1600 ml.
Is 9 watts the settled power figure?
The table says 9 watts. That is far below other semiconductor minis in this set, so treat it as an unresolved listing figure.
How many reviews support the 5.0 score?
Three. That is too small a sample to treat the score as stable.
The TOIOVCU D11A is a 22.5 W mini whose title claims 360 ml a day, at £49.99. amazon.co.uk shows 4.8 from 59 reviews. UK comments that match the product describe a quiet box room, wardrobe or bathroom, a timer for overnight use, and easier carrying at about 1.15 kg. Some users report less window condensation and faster indoor drying, which is a lot to ask of 360 ml a day, so treat those reports as small-space results. The tank size is not listed separately from the daily claim. The review file also contains a humidifier comment and a mention of castors this listing does not specify. Auto defrost is claimed, with no extraction figure for a cold room.
Pros
Cons
Best for: You want a light mini for a box room or wardrobe and you will judge it on 360 ml a day, not on a room-sized headline.
Less suitable: You need a known tank capacity or a machine for a streaming bedroom.
Specifications
Common questions
How much water does the title claim?
360 ml a day. The listing does not separate a larger tank size from that figure.
Will it treat a large room?
The extraction claim is 360 ml a day at 22.5 W. That is a small-space rate, not a whole-flat compressor.
Does it defrost itself?
Auto defrost is claimed. No extraction figure at a low room temperature is given.
The QERILAY is a dual-semiconductor mini, not a compressor, claiming up to 800 ml a day at 70 W, with a timer out to 48 hours, at £59.98. amazon.co.uk shows 4.7 from 38 reviews. UK reviewers call it quiet enough for a bedroom or bathroom and say it collects a noticeable amount for its size. One person said it keeps a 3 × 4 m bedroom damp-free but “works badly” for the money. The listing tank is 2500 ml, while some UK reviews measure about 1.7 litres. Auto defrost is claimed, with no litre rate at a low temperature. Non-UK reviews in the saved listing were not used here.
Pros
Cons
Best for: You want a larger mini than a 22.5 W unit for one bedroom, and you can check the tank size when it arrives.
Less suitable: You expect 2.5 litres of tank or compressor extraction in a cold flat.
Specifications
Common questions
How often would you empty it?
The listing claims up to 800 ml a day into a 2500 ml tank, so not every few hours if those figures hold. Some UK reviews describe a tank nearer 1.7 litres.
Does it work in a cold room?
Auto defrost is claimed. No extraction rate at a low temperature is given, and 800 ml/day is still a mini-class figure.
Can the lights be turned off?
Yes. The bullets say the RGB light can be fixed, gradient, or fully off.
The finade SC1 is a 22.5 W semiconductor mini with an 1800 ml tank and a 4 or 8 hour timer, at £43.69. The title says 400 ml a day, the bullets say up to 500 ml in 24 hours at 30°C and 85% relative humidity, and the table says 0.4 litres, so all three stay on the listing. amazon.co.uk shows 4.7 from 20 reviews. UK comments call it quiet in a small room or bathroom, and one user said indoor laundry dried faster and smelled less musty. A table room size of about 215 square feet does not match a half-litre daily rate. Twenty reviews, several of them one line, are a thin base. German-language reviews in the file were ignored.
Pros
Cons
Best for: You want a 22.5 W mini with a large tank for a bathroom or small bedroom, and you can ignore the large-room line.
Less suitable: You are sizing a lounge from the 215 square foot field. The daily claims are under half a litre.
Specifications
Common questions
Is it suitable for a large room?
The table lists about 215 square feet, but the daily claims are 400–500 ml. That extraction does not support a large room.
Does it need constant emptying?
The tank is 1800 ml and the daily claim is under 500 ml, with shut-off when full. You would not empty it several times a day at the claimed rate.
Can it run continuously?
The timer options listed are 4 and 8 hours, plus auto shut-off when the tank is full. A humidistat that holds a setpoint is not listed.
The Pro Breeze PB-18-UK is a 200 W compressor listed at 12 litres a day, with a 30–80% humidistat, a 24-hour timer, a 1.8 litre tank and a hose, at £134.99. amazon.co.uk shows 4.6 from 5,685 reviews, the largest file in this set. In the first 50 UK reviews, owners describe it as quiet for a compressor, useful beside indoor washing, and able to cut condensation and a damp smell. Wheels and a handle come up often, and some buyers add a second unit. The compressor clicks when it stops, and a few owners still find it heavy to move. It does not replace damp-proofing. The amazon title says Which? Best Buy, while Pro Breeze’s own 12 litre page describes a Which? Great Value award, so this comparison does not treat the title as a verified Best Buy.
Pros
Cons
Best for: You want a 12 litre compressor for a heated flat, with a humidistat and a hose, and a review file large enough to read.
Less suitable: You need a verified Which? Best Buy, or a unit that stays quiet enough for a very light sleeper. The click is a repeated note.
Specifications
Common questions
Is the Which? Best Buy title confirmed here?
No. The amazon.co.uk title says Which? Best Buy. Pro Breeze’s own 12 litre page describes a Which? Great Value award. This comparison does not treat the title as a verified Best Buy.
Can you leave the hose connected?
The bullets describe a removable hose for continuous drainage and a 1.8 litre tank. You still need a drain the water can run down to.
What humidity can you set?
30–80% on the listing. Once the target is reached the unit is described as turning off.
The ARIBIO D015R2E-12L is a 210 W compressor listed at 12 litres a day, with a 2 litre tank, a drain hose and a 30–80% target, at £129.99. amazon.co.uk shows 4.6 from 1,139 reviews. In the first 50 UK reviews, owners report a lot of water, less window condensation and useful indoor laundry, and one owner had kept a unit for three years. Sleep mode is claimed at 35 dB, and one small rental found the night setting quiet enough. Several other reviewers still call it noisy in sleep mode. The humidity limit is not remembered, so the machine can keep running, and at 10.5 kg it is heavy on stairs. One buyer added a separate hygrometer because they doubted the built-in reading.
Pros
Cons
Best for: You want a 12 litre compressor with a hose and a child lock, and you can live with resetting the humidity target.
Less suitable: You need a bedroom machine that stays quiet in sleep mode, or a setpoint that is still there the next morning.
Specifications
Common questions
Can you set a humidity target?
Yes. The listing lets you set 30–80%, with blue, green and red lights around 45% and 65%. Reviews say the chosen target is not remembered.
Is a drain hose included?
Yes. The box list includes a drain pipe and a 2 litre tank that shuts the unit off when full.
Is there a child lock?
Yes. The listing says press and hold the child lock to turn it on or off.
The Bosch Dry 1000 is listed for rooms up to 17 m², with a claimed 10 litres a day into a 2.5 litre tank, at 175 W and 240 V, for £159.00. Across the first UK reviews in a file of 165 at 4.6 stars, owners use Night and Laundry modes while drying clothes indoors, and one leak-drying report collected about 2.5 litres in 24 hours. A bungalow owner found it quieter than an older EcoAir. The same sample includes bedroom noise, a night-mode light that is not fully dark, and tank dividers that make emptying fiddly. One long bathroom run did not approach the 10 litre claim, and automatic mode will not run if the room is too cold. A filter is an extra cost, and continuous drainage is not stated on the listing.
Pros
Cons
Best for: You dry washing in a heated room up to about 17 m² and want named night and laundry modes.
Less suitable: You need a hose left on a drain, or the room is cold enough that automatic mode refuses to start.
Specifications
Common questions
What room size does Bosch state?
The listing limits the Dry 1000 to rooms up to 17 m², with a claimed extraction of 10 litres a day into a 2.5 litre tank.
Does it have a laundry mode?
Yes. The listing names Auto, Night and Laundry modes, plus castors and a handle. A clock timer is not listed.
Will automatic mode run in a cold room?
One UK review says automatic mode will not run if the room is too cold. The listing does not give a minimum temperature.
The EasyAcc lists up to 400 ml a day at 30°C and 80% relative humidity, with a 1200 ml tank and automatic shut-off, at £48.99. amazon.co.uk shows 4.3 from 3,472 reviews, the second-largest file in this set. Buyers use it in a bedroom, studio or utility room and describe a visible amount of water day to day. The specification table says 790 W while a bullet says 0.79 kW after 24 hours, so the running power is unresolved and should not be read as a 790 W heater. Noise is claimed under 35 dB. UK reviews include both “not too noisy” and a unit that became very noisy after about two months. One unit arrived not working.
Pros
Cons
Best for: You want a widely reviewed mini for a bedroom or utility room and you will ignore the 790 W table line.
Less suitable: You need a known wattage for a running-cost sum, or compressor performance in a damp flat.
Specifications
Common questions
Does it use 790 watts?
The specification table says 790 watts. A bullet says 0.79 kW after 24 hours. Those cannot both be the running power, so the figure is left unresolved.
How quiet is the claim?
The listing says under 35 dB. UK reviews include both “not too noisy” and complaints that a unit was not quiet or became noisy after about two months.
What is the tank size?
1200 ml, with automatic shut-off and a red light when it is full. Daily extraction claimed is 400 ml at 30°C and 80% RH.
The GW MD307B is a Peltier mini, not a compressor. The listing claims up to 300 ml a day at 30°C and 80% relative humidity, into a 1000 ml tank, at 22.5 W, for £37.99. amazon.co.uk shows 4.2 from 1,024 reviews. Reviewers use it on a shelf, in a wardrobe or in a small bedroom, and the tank lid makes emptying less messy. It is not enough for heavy window condensation, and one run on full power did not clear condensation after several hours. Sleep mode is called inefficient by one reviewer, and the beep at the end of the timer is loud enough to wake someone. Units in the sample stopped collecting water after about six months or failed inside a year.
Pros
Cons
Best for: You want a small Peltier unit for a wardrobe, windowsill or single bedroom, and you accept a millilitre daily rate.
Less suitable: You are trying to dry a flat or clear streaming windows. The listing says it is not for whole floors.
Specifications
Common questions
Is this enough for a whole flat?
No. The listing says 5–15 m² and not for whole floors, and the extraction claim is 300 ml a day at 30°C and 80% relative humidity.
Does it shut off when the tank is full?
Yes. The listing describes a red light and a beep, then shut-off, on the 1000 ml tank.
Can you use it in a caravan?
The bullets name caravans, wardrobes and windowsills. No IP rating is stated, so keep it out of splashes.
The Senelux X600B is a 21 W Peltier mini claiming about 250 ml a day at 30°C and 80% relative humidity, into a 500 ml tank, at £26.99. amazon.co.uk shows 4.2 from 632 reviews. Owners put it in a cupboard, porch, en suite or spare bedroom, and one report of Velux condensation improved. A bedroom test in the file collected about 50 ml in 8 hours, which is well under the daily headline. It can freeze in an unheated room, and one wall adaptor ran too hot to hold. Units in the sample stopped after a few months or inside a year, including a repair that a reviewer says was never completed. Stop using a plug that overheats.
Pros
Cons
Best for: You want the cheapest unit in this set for a closed cupboard or a small spare room, and you will unplug a hot adaptor.
Less suitable: You need litres a day, or the space is unheated. A 250 ml claim will not dry a wash.
Specifications
Common questions
What does 500 ml refer to?
The tank. Daily extraction is about 250 ml at 30°C and 80% relative humidity.
Does it turn off when full?
Yes. The listing says it shuts off and a yellow LED comes on.
Any safety note from reviews?
One UK review says the wall adaptor gets too hot to hold. Another reports freezing in an unheated room. Stop using a plug that overheats.
Shelf date: 20 October 2026. Source: the twelve amazon.co.uk listings in this display file and the listing review notes for the same ASINs. Not a lab test. A litre-per-day headline, a decibel claim, or a Which? line in an amazon title is not scored as a UK measurement. Extraction claims at 30°C and 80% relative humidity are kept as listing claims. Weights sum to 100.
Amazon evidence
30%Star rating on amazon.co.uk, plus points for the review count. A 5.0 from fewer than 100 reviews is capped at 14. Fewer than 30 reviews is capped at 10. Fewer than 10 reviews is capped at 8. A 4.6 from 5,685 reviews scores higher than a 5.0 from 3.
Listing fit
40%A coherent litres-per-day figure, a separate tank size, a numeric humidistat or named modes, a drain hose, and a wattage that can sit beside the other units in that class. Conflicts score down: two extraction figures, a room size the daily rate cannot support, or a wattage field that cannot be the running power.
Review outcome
20%UK reviews that describe collected water, less window condensation, or indoor laundry score higher than a file of one-line praise. Repeated noise, a setpoint that is not remembered, a unit that stops within a year, a hot plug, or an empty tank in a cold room score down.
Value
10%Shelf price in GBP against the extraction class and a review file you can read. £26.99 does not score as a room dehumidifier. £99.99 does not score as proven when the sample is 7 reviews and the listing prints both 8 and 12 litres a day.
Job and temperature. Heated room and condensation or indoor laundry: compressor. Unheated cellar or garage that stays below about 10°C: a desiccant, which this twelve-ASIN set does not include. A mini Peltier unit only for a cupboard, wardrobe, caravan corner, or very small closed space.
Refrigerant (compressor) units chill a coil so water condenses. They suit a warm room and weaken when it is cold. Desiccant units use a wheel and a heater, work in the cold, and usually cost more to run; none are in this set. Peltier minis have no compressor, draw roughly 20–70 W when the listing is coherent, and collect millilitres.
Mistakes: trusting a 30°C litre headline; expecting 300 ml/day to dry a flat; running with windows open; wiping mould and ignoring the leak; taking an amazon “Which?
Best Buy” title as proof.
Call the landlord or a professional for a tide mark, a growing wet patch, widespread mould, or a burning plug.
Job and temperature. Heated room and condensation or indoor laundry: compressor. Unheated cellar or garage that stays below about 10°C: a desiccant, which this twelve-ASIN set does not include. A mini Peltier unit only for a cupboard, wardrobe, caravan corner, or very small closed space.
Extraction versus tank. “12 litres/day” is a claimed daily maximum, not the tank size. Tanks on the compressors here are 1.7–2.5 litres. Mini claims are about 250–800 ml/day, usually stated at about 30°C and 80% relative humidity.
Three typical situations, each with a recommendation from this comparison.
Renters with wet windows need a compressor sized to the room, and still report leaks and broken extractors. You want a 12 litre compressor for a heated flat, with a humidistat and a hose, and a review file large enough to read.
Households drying washing indoors want a laundry mode, a shut door, and an airer beside the unit. You want a 12 litre compressor with a hose and a child lock, and you can live with resetting the humidity target.
Cold spare rooms, basements, and unheated caravans are a poor match for a mini or a small compressor bought on stars alone.
The top pick is the Pro Breeze 12L/day at about £134.99. It scores 88, the highest in this set, rated 4.6 from 5,685 reviews. Best value is the ARIBIO 12L/day at about £129.99, a different ASIN, with score 80. Skip the top pick if the limit in its listing is the job you actually have.
ARIBIO 12L/day
Best value on a different ASIN, the ARIBIO 12L/day at about £129.99.
