Our verdict
Our verdictResearched

Genuine cold-space capability — desiccant, rated to 1°C, with a three-year warranty — for sensible money, and it quotes 7.5 L/day at an explicitly stated 20°C/60% so the figure means something. The trade-off is in the name: 'Simple' is the rotary-dial version, with no electronic controls or display. If you want the machine to sit in a cold space and just run, that is a fair swap.

Best for The best-value way to dry a cold garage, conservatory or caravan.

Good
  • Rated to 1°C — works where the compressor units aren't rated to
  • 7.5 L/day at an explicitly stated 20°C/60%, so it's genuinely comparable
  • 34 dB(A) on its energy-saving setting, and a three-year warranty
Worth knowing
  • Rotary-dial control only — no electronic controls or display
  • 47 dB(A) on turbo, so the fast setting is a noisy one
  • The silver-treated filter is marketed as antibacterial, but EcoAir publishes no test standard

Who shouldn't buy it: Don't buy it if you want digital control and a readout — the Pro Breeze 12L has an automatic humidity sensor and display, though only for heated rooms.

Our verdict
Our verdictResearched

Meaco's newer Arete Two in its 10L size, with app and voice control, an on and off timer, a DC fan motor and a 5-year warranty. The 10.75 L/day headline is at 30°C and 80%, and Meaco's own table gives 4.19 L/day at 20°C and 60%, so it suits a small heated room rather than a whole house. Against the Arete One 12L on this page it adds app control, a louvre and a fuller display, but extracts less at 20°C and 60% (4.19 against 5.23 L/day).

Best for Small flats and bedrooms where you want app control and a quiet unit.

Good
  • 35 dB(A) on the lowest fan speed, 44 dB(A) on high
  • Five-year warranty, matching the Arete range
  • App, Alexa and Google control, plus a 1–24 hour on and off timer
Worth knowing
  • Only 1.38 L/day at 10°C and 60% in Meaco's own table, so it needs a heated room
  • 2.5 litre tank, slightly smaller than the ABC 12L's 2.6 litres
  • Wall-mountable, but the wall brackets and drain hose are sold separately

Who shouldn't buy it: Don't buy it if you need to dry a large home quickly. The Meaco 20L Low Energy has far more capacity, and a desiccant unit is the right choice for a cold room.

Our verdict
Our verdictResearched

EcoAir's largest domestic desiccant model, rated by the maker at 11 L/day, and the figure is quoted at a stated 20°C and 60%, so it is directly comparable with other units on this page. It suits 3 to 6 bedroom homes by EcoAir's own sizing, has a digital humidity display, 2 to 12 hour timer and a three-year warranty. Desiccant units give off warmth and draw more power than compressors, so it fits cold spaces and winter use better than a hot summer room.

Best for Cooler rooms, garages and whole-home use where a compressor unit struggles.

Good
  • 11 L/day at a stated 20°C and 60%, a clear and fair test point
  • 4.2 litre tank and a continuous drainage hose option
  • Light for its capacity at 7.5 kg, with a three-year warranty
Worth knowing
  • EcoAir lists 420 W on low and 735 W on high, noticeably more power than a compressor unit of similar output
  • 47 dB(A) on the high setting
  • It warms the room as it runs, which EcoAir pitches as a winter benefit but is unwelcome in a warm summer room

Who shouldn't buy it: Don't buy it if you only need to dry a warm, heated living space at the lowest running cost. A compressor unit such as the Meaco 20L Low Energy on this page draws less power there.

MeacoDry Arete One 20L

The big sibling of the Arete One 12L: the same quiet design and five-year warranty, with 20 L/day at 30°C/80% and a 4.8-litre tank, nearly twice the 12L's. It was £259.99 at Meaco on 1 November 2026, the same as Meaco's older 20L Low Energy, and weighs 15kg. For one damp room or a flat the 12L is enough; this is for a larger house or a lot of laundry dried indoors.

Best for Damp and indoor laundry in a larger heated home

Good
  • 20 L/day at 30°C/80% and 12 L/day at 27°C/60% (Meaco)
  • 4.8-litre tank, nearly twice the 12L's
  • H13 HEPA filter and an air-purifier mode; five-year warranty (Meaco)
Worth knowing
  • 15kg: heavier to move between rooms than the 12L-class units
  • Rated only to 5°C, like every compressor unit here
  • No hose in the box: continuous drainage needs a standard garden hose

Who shouldn't buy it: Don't buy it if the room is an unheated garage or caravan in winter: a desiccant such as the EcoAir DD1 Simple MK3 keeps working in the cold. And for a flat or one damp room, the Arete One 12L does the job for less.

Our verdict
Our verdictResearched

One of two 20L-class units on this page with the Russell Hobbs RHDH2002, it has the bigger 6 litre tank, and Meaco prints the whole extraction table rather than one flattering number. The 20.38 L/day headline is at 30°C and 80% humidity, and the figure at a more typical 20°C and 60% is 8.48 L/day, so judge it on that second number. It is louder than the 12L-class units and, as a compressor machine, it belongs in heated rooms.

Best for Drying a whole 3–4 bedroom house or a big laundry load in a heated home.

Good
  • Meaco publishes extraction at six temperature and humidity combinations
  • 6 litre tank means fewer trips to the sink
  • Continuous drainage outlet (hose not included) and a 2-year warranty
Worth knowing
  • Meaco quotes up to 46 dB(A) at one metre, louder than the ABC 12L
  • Meaco's own table gives 2.52 L/day at 10°C and 60%, so it is weak in a cool room
  • About 13.6 kg, heavier than the 12L-class units

Who shouldn't buy it: Don't buy it if the space is a cold garage or outbuilding. Meaco rates it for 5–35°C and its own table shows output falling steeply in a cool room, so a desiccant unit such as the Pro Breeze 10L Desiccant or EcoAir DD1 Simple MK3 fits better.

MeacoDry ABC 12L
Compressor, rated 5–35°C · 12 L/day (30°C/80%) · 7.5 (27°C/60%) · 2.6 L · 36–40 dB(A) at 1 m

Our verdict
Our verdictResearched

A plain, well-documented 12L compressor unit with a digital display, a variable humidistat and a 6-hour laundry mode. Meaco quotes 12 L/day at 30°C/80% and says plainly that the figure at 27°C/60% is 7.5 L/day, so the label is easy to read honestly. Compared with the MeacoDry Arete One 12L on this page it has no air purifier filter and a two-year rather than five-year warranty.

Best for A quiet, compact unit for a flat or small house with a heated living space.

Good
  • Meaco states the test conditions for both of its extraction figures
  • 36–40 dB(A) at one metre, quiet enough for a bedroom or landing
  • Digital display, variable 30–80% humidistat and a timed laundry mode
Worth knowing
  • Two-year warranty, against five years on the Arete range
  • Meaco's table gives 1.88 L/day at 10°C and 60% (high fan), so it needs a warm room
  • 2.6 litre tank fills quickly in a damp home unless you use the drain hose

Who shouldn't buy it: Don't buy it if the room is unheated. Meaco rates it for 5–35°C, and the desiccant EcoAir DD1 Simple MK3 or Pro Breeze 10L Desiccant are built for cold rooms.

EcoAir DC12 MK3

Our verdict
Our verdictResearched

The value compressor pick: 12 L/day at a stated 30°C/80%, 39 dB(A), and — unusually — a published power draw of 210W low and 240W high, so you can work out the running cost before you buy. The catch is the 15°C floor, the highest of any full-size unit here, which rules out exactly the unheated spaces people most often have in mind.

Best for A cheap, compact compressor unit for a heated room.

Good
  • The cheapest full-size unit here
  • Publishes its power draw: 210W low, 240W high
  • 39 dB(A) from a genuinely compact body
Worth knowing
  • Rated only from 15°C — not for an unheated garage or a cold conservatory
  • Two-year warranty, shorter than EcoAir's own three-year desiccant cover
  • 2L tank fills quickly when the unit is working hard

Who shouldn't buy it: Don't buy it if the space drops below 15°C — EcoAir's own DD1 Simple MK3 is rated to 1°C for broadly similar money.

Our verdictResearched

The slimmer, lighter sibling of the DD3 Classic: 10 L/day at a stated 20°C and 60%, 6.8 kg and a footprint of about 32 by 21 cm, according to EcoAir. EcoAir pitches it at homes and unheated spaces up to 85 m². It gives up some tank size and a little capacity against the Classic MK3 on this page, in return for being easier to move and to fit into a narrow space.

Best for Smaller or unheated rooms where you want desiccant drying in a lighter, slimmer body.

Good
  • Stated 10 L/day at 20°C and 60%, so the figure is comparable
  • 6.8 kg and a narrow footprint, easier to carry than the Classic MK3
  • Washable antibacterial filter, and stockists list a three-year warranty
Worth knowing
  • About a 3 litre tank (EcoAir's own page gives both 3 and 3.5 L), so it fills sooner than the Classic MK3's 4.2 litres
  • 49 dB(A) on high, and retailers disagree on its quietest figure, so check the manual
  • EcoAir lists up to 670 W on high, much more than a compressor unit

Who shouldn't buy it: Don't buy it if you want the most daily extraction for a large heated home. A 20L compressor model such as the Meaco 20L Low Energy on this page covers more ground.

Our verdictResearched

A desiccant machine rated down to 1°C, where the compressor units on this page lose most of their output. Pro Breeze states its 10 L/day at 20°C and 60% in the manual, which is the fair way to read it, and the built-in humidistat, 12-hour timer and 3 litre tank make it practical to leave running. Against the EcoAir DD1 Simple MK3 it has a higher stated extraction figure at the same 20°C and 60%, a larger tank and digital controls, though the DD1 is quieter on its eco setting.

Best for Drying a cold garage, cellar, outbuilding or unheated spare room.

Good
  • Rated to run from 1°C, so it keeps working in a cold room
  • Built-in humidistat, 12-hour timer and a 2 m drain hose in the box
  • 10 L/day stated at an explicit 20°C and 60% in the manual
Worth knowing
  • The manual lists 620 W on high and 370 W on low, well above a compressor unit's draw
  • Pro Breeze quotes 44 dB, louder than the 36–40 dB(A) of the MeacoDry ABC 12L
  • Only one extraction figure is published, with no results at colder temperatures

Who shouldn't buy it: Don't buy it if the room is already heated and you want the lowest running cost. A compressor model such as the MeacoDry ABC 12L uses far less power in a warm room.

Pro Breeze's 20L smart compressor model, with Wi-Fi app and Alexa or Google control, a 24-hour timer, a laundry mode and two drain hoses in the box. Pro Breeze quotes up to 20 L/day but does not state the temperature and humidity it applies to, so treat it as a best-case figure and expect less in a normal room. It is an app-controlled alternative to the Meaco 20L Low Energy on this page, but with a thinner published evidence trail.

Best for A heated home that wants 20L capacity and app control without paying for a premium brand.

Good
  • Two 1 m drain hoses included for continuous drainage
  • App and voice control, with a 24-hour timer
  • 36 dB stated noise level and 4 litre tank
Worth knowing
  • The 20 L/day maximum comes with no stated test conditions
  • Pro Breeze publishes a 5–32°C working range, so it is not for cold rooms
  • B&Q lists a 1-year warranty, shorter than the 5 years on the Meaco Arete range

Who shouldn't buy it: Don't buy it if you want an extraction figure at stated test conditions; the Meaco 20L Low Energy on this page publishes one. For an unheated room, a desiccant unit such as the EcoAir DD3 Classic MK3 fits better.

Our verdict
Our verdictResearched

The most capacity per pound here: 20 L/day at the industry-standard 30°C/80% condition, into the largest tank in the group, for well under what the desiccant units cost. Two honest caveats. At 47.5 dB it is the loudest unit on this page, and its own manual says not to place it where the temperature will fall below 5°C — so it is not the big garage machine its capacity implies. The defrost function protects its coils; it does not make it a cold-room unit.

Best for Drying out a larger or wetter heated space, or a room after a leak.

Good
  • 20 L/day — the highest capacity here and the cheapest per litre
  • 3L tank, the largest in this group, so fewer trips to empty it
  • Comfortably cheaper than the desiccant units
Worth knowing
  • 47.5 dB — the loudest here; fine in a utility room, wrong for a bedroom
  • The manual says don't place it where temperature falls below 5°C
  • Russell Hobbs doesn't publish the test condition or refrigerant on its own pages, so the 30°C/80% figure is attributed to the industry standard rather than the maker

Who shouldn't buy it: Don't buy it if you need it in an unheated garage — capacity doesn't help when the manual rules out the temperature, so choose a desiccant unit instead.

A capable, widely stocked compressor unit with an automatic humidity sensor and display, rated for rooms up to 20 m² and from 5°C to 32°C. The weakness is comparability: Pro Breeze quotes 12 L/day but publishes no test temperature or humidity for it, so that number cannot be set against Meaco's or EcoAir's stated-condition figures. Pro Breeze also advertises a Which? award for this model; we could not verify it with Which? directly, and the brand's own listings describe it two different ways.

Best for A heated room where you want automatic humidity control and a display.

Good
  • Automatic humidity sensor and display — set a level and leave it
  • Rated for rooms up to 20 m², with 80 m³/h airflow
  • 38 dB and easy to find at UK retailers
Worth knowing
  • The 12 L/day claim has no published test condition, so it isn't comparable with the others
  • 1.8L tank — the smallest of the full-size units here, so more emptying
  • Rated 5–32°C: like every compressor unit, output falls away as the room cools

Who shouldn't buy it: Don't buy it if the space is unheated — a desiccant unit such as the EcoAir DD1 Simple MK3 is the right tool for a cold room.

The right default for a normal, heated British house: quiet at 35–38 dB(A), the largest tank of the 12L-class units here, and a five-year warranty that is the longest in this group. Meaco is also the only brand on this page to publish its full extraction matrix rather than one flattering number — 12.18 L/day at 30°C/80% falling to 1.95 L/day at 10°C/60% — which tells you exactly where its limits are.

Judged as what it is — a 1kg thermoelectric unit for an enclosed cupboard or wardrobe — it is fine, quiet and cheap. Judged as a room dehumidifier it simply isn't one: up to 0.25 L/day is around a fiftieth of the full-size units here. The real problem is where people put it, because the 15–30°C rating is the warmest and narrowest in this group, while listings routinely picture it in caravans and garages.

Best for A wardrobe, cupboard or small enclosed cabin — not a room.

Good
  • Just 1 kg — sits in a wardrobe or cabinet without fuss
  • 33 dB(A) or below, with no compressor cycling on and off
  • Roughly two days per fill at its rated output, so it isn't constant emptying
Worth knowing
  • Up to 0.25 L/day — about a fiftieth of a 12L unit; it will not dry a room
  • Rated 15–30°C, so it's wrong for the cold garage, caravan or boat it's often marketed for
  • No published test condition for the 0.25 L/day figure

Who shouldn't buy it: Don't buy it if the space is cold, or bigger than a cupboard — a desiccant unit rated to 1°C, like the EcoAir DD1 Simple MK3, is the honest answer.

The honest bit: this manages damp, it doesn't fix the cause
Two things worth saying before you spend anything. First, the running cost is the real cost. A dehumidifier can run for hours a day through a damp winter, so check the stated wattage — EcoAir publishes 210W on low and 240W on high for the DC12 MK3, for example — and work out what that means on your tariff before you compare purchase prices. Second, and more important: a dehumidifier manages the symptom, not the source. If the moisture is coming from a leak, failed pointing, blocked airbricks, a broken extractor fan or rising damp, the fix is that repair plus proper ventilation. Running a machine forever instead is an expensive way to live with a solvable problem. Find the source first, then decide whether you still need the dehumidifier — quite often you'll want one anyway, but for a smaller job than you thought.

Before you buy

Start with the extraction figure, then discount it.

Litres per day is measured at a stated temperature and humidity, and the industry's favourite condition — 30°C and 80% relative humidity — is not a British house in November. Meaco is unusually open about this: the Arete One 12L is rated at 12.18 L/day at 30°C/80%, but the same manufacturer's published matrix shows 5.23 L/day at 20°C/60% and 1.95 L/day at 10°C/60%. So two units can only be compared when both quote the same condition. Pro Breeze's 12L and OmniDry 20L claims state no test condition, so they cannot honestly be lined up against stated-condition figures.

The type matters more than the litres.

Compressor units condense moisture onto a cold coil and lose efficiency as the room cools, hence their temperature floors: the EcoAir DC12 MK3 is rated from 15°C, the Meaco and Pro Breeze compressor units from 5°C, and the Russell Hobbs RHDH2002's manual sets a 5°C minimum. Desiccant units use a moisture-absorbing rotor and keep working in the cold — the EcoAir DD1 Simple MK3 and Pro Breeze 10L Desiccant are rated to 1°C. So: heated house, compressor. Unheated garage, conservatory, caravan or cold spare room, desiccant. A defrost function protects a compressor's coils; it does not make it a cold-room machine.

Then the everyday things.

Noise sets where it can live: 34–39 dB(A) covers the Meaco Arete One, EcoAir DC12 MK3 and the DD1 Simple MK3 on its quiet setting, while the Russell Hobbs at 47.5 dB belongs in a utility room, not a bedroom. Quieter settings also extract less. Tank size decides how often you empty it — 1.8L on the Pro Breeze 12L against 6L on the Meaco 20L Low Energy — and most full-size units take a continuous drain hose. And check the wattage: desiccant units draw more, with EcoAir listing 420–735 W for the DD3 Classic MK3 against 210–240 W for the compressor DC12 MK3.

Finally, size to the job rather than to the biggest number.

None of these machines is a medical device and none should be bought as a treatment for anyone's health condition — the goal is drier air and fewer damp surfaces. For one room, drying laundry indoors, or window condensation, a 12L-class unit is plenty. A 20L-class unit is for a larger or wetter space, or for drying a property out after a leak. At the other end, the Pro Breeze 500ml mini is a wardrobe and cupboard device at up to 0.25 L/day, roughly a fiftieth of a full-size unit, and will not dry a room.

How we choose

We verify every product's specifications against at least two independent sources, re-check its UK price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labelled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test. When two products are close, commission can decide which one we pick. A clearly better product always wins. Read our full methodology →

Common questions

What's the best dehumidifier in the UK?

For everyday condensation and damp in a heated home, the MeacoDry Arete One 12L. For small flats and bedrooms where you want app control and quiet running, the MeacoDry Arete Two 10L. For a cold garage, conservatory or caravan, a desiccant such as the EcoAir DD1 Simple MK3 is the best-value choice, and the EcoAir DD3 Classic MK3 covers cooler rooms and whole-home use. For a whole 3 to 4 bedroom house or a big laundry load, the Meaco 20L Low Energy.

Is a dehumidifier worth buying for damp in a small terraced house this winter?

Often, yes, if the damp is condensation: warm, moist air meeting cold walls and windows, which is the usual winter pattern in UK homes. In a heated house a compressor unit suits best; in a cold room, a desiccant one. Expect far less than the litres on the box in a British room in winter, and budget for the electricity, because it will run for hours a day. If the damp comes from a leak, failed pointing, blocked airbricks or a broken extractor fan, fix that first: a dehumidifier lowers the humidity mould needs, but it won't remove mould that's already there.

Compressor or desiccant — which one do I actually need?

It depends on how warm the space is, not how big it is. Compressor units condense moisture onto a cold coil and lose efficiency as the temperature drops, so they suit heated rooms. Desiccant units use a moisture-absorbing rotor and keep working in the cold. The manufacturers' own ratings make the split clear: the EcoAir DC12 MK3 is rated from 15°C, while the desiccant EcoAir DD1 Simple MK3 is rated down to 1°C. Heated house, compressor. Garage, conservatory, caravan or cold spare room, desiccant.

Will a 12L dehumidifier really remove 12 litres a day?

No — not in a British home. That figure is measured at a stated lab condition, commonly 30°C and 80% relative humidity, which is far warmer and wetter than a UK room. Meaco publishes the whole curve for the Arete One 12L: 12.18 L/day at 30°C/80%, 5.23 L/day at 20°C/60% and 1.95 L/day at 10°C/60%. Same machine, roughly a sixfold difference. Treat the headline as a comparison tool only, and only when both manufacturers quote the same condition.

Can I put a dehumidifier in an unheated garage over winter?

Only a desiccant one. Of the units here, the EcoAir DD1 Simple MK3 and Pro Breeze 10L Desiccant are rated down to 1°C. The compressor units are not: the EcoAir DC12 MK3 is rated from 15°C, the Meaco and Pro Breeze compressor units from 5°C, and the Russell Hobbs RHDH2002's manual says not to place it where the temperature will fall below 5°C. A defrost or frost-protection function stops a compressor unit's coils icing up — it does not make the machine suitable for a cold room.

How much does a dehumidifier cost to run?

Work it out from the wattage, because that is the only figure that will be true for your tariff and your house. EcoAir publishes 210W on low and 240W on high for the DC12 MK3, for instance: convert to kilowatts, multiply by the hours you expect it to run, then by your unit rate. Over a damp winter these machines run for hours a day, so the electricity is a real ongoing expense — compare it alongside the purchase price rather than after it.

Will a dehumidifier get rid of mould?

It lowers the humidity that mould needs, which helps — but it will not remove mould that is already there, and it does not address why the moisture is arriving. UK government and NHS guidance says to deal with the source. If that is a leak, failed pointing, blocked airbricks, a broken extractor fan or rising damp, the repair plus proper ventilation is the fix. We make no health claims for any of these machines, and none of them should be bought as a treatment for a medical condition.

Is a dehumidifier quiet enough to have in a bedroom?

Some are. The Meaco Arete One 12L is stated at 35–38 dB(A), the EcoAir DC12 MK3 at 39 dB(A), and the EcoAir DD1 Simple MK3 at 34 dB(A) on its energy-saving setting. The Russell Hobbs RHDH2002 is not: it is stated at 47.5 dB. Remember that the quiet settings are also the slow settings, so a unit run quietly will take longer to do the same work.

Do the little 'mini' dehumidifiers actually work?

For a wardrobe, cupboard or small cabin, within their limits. The Pro Breeze 500ml mini is rated at up to 0.25 L/day — around a fiftieth of a 12L unit — which is roughly two days to fill its 0.5L tank. The catch is temperature: it is rated 15–30°C, warmer and narrower than the cold garages, caravans and boats these devices are often pictured in. If the space is cold, a mini is the wrong product and a desiccant unit is the right one.
