Best dehumidifiers UK (2026) — compared & price-tracked
Damp in a UK home is usually a cold-weather problem: warm, moist air meeting cold surfaces. A dehumidifier is a genuinely useful tool for managing that, but the headline litres-per-day on the box is a lab figure, and the type you buy matters far more than the number. We've compared seven units against the manufacturers' own published documentation and price-tracked them for UK buyers. The single most useful thing on this page is the temperature rating, because it decides whether a machine will do anything at all in the room you had in mind.

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%. That is roughly a sixfold spread from one machine, published by the brand that sells it. It also means two units can only be compared when both quote the same condition. Pro Breeze's 12L claim comes with no stated test condition at all, so it cannot honestly be lined up against the Meaco and EcoAir figures.
The type matters more than the litres. Compressor (refrigerant) dehumidifiers condense moisture onto a cold coil and lose efficiency as the room gets colder, which is why manufacturers set temperature floors: the EcoAir DC12 MK3 is rated from 15°C, the Meaco Arete One 12L and Pro Breeze 12L from 5°C, and the Russell Hobbs RHDH2002's manual says not to place it where the temperature will fall below 5°C. Desiccant units use a moisture-absorbing rotor instead and barely notice the cold — the Meaco DD8L Pro drops only from 7.97 to 6.89 L/day between 20°C and 10°C, and both it and the EcoAir DD1 Simple MK3 are rated down to 1°C. So: heated house, compressor. Unheated garage, conservatory, caravan or cold spare room, desiccant. A frost or defrost function on a compressor unit protects its own coils from icing; it does not turn it into a cold-room machine.
Then the everyday things, which decide whether the unit gets used or resented. 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 DD8L Pro at 50 dB on speed 3 and the Russell Hobbs at 47.5 dB belong in a garage or a closed utility room rather than a bedroom. Quieter settings also extract less, so a unit run quietly is a slower unit. Tank size decides how often you empty it — 1.8L on the Pro Breeze against 3L on the Russell Hobbs is a real difference when a machine is working hard — and most full-size units will take a continuous drain hose if you can site them near a drain. And check the wattage while you're comparing, because that number, not the sticker price, is what you pay every winter.
Finally, size to the job rather than to the biggest number. Damp and mould in homes is recognised in UK government and NHS guidance as something to deal with rather than live with, but 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 unit like the Russell Hobbs 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 no amount of patience will make it dry a room.
Top pick: MeacoDry Arete One 12L Dehumidifier & Air Purifier. 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.

Who it's for: Everyday condensation and damp in a heated home.
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.
- Publishes the full extraction matrix, not just the 30°C/80% headline
- 35–38 dB(A) — liveable on a landing or in a home office
- Five-year warranty, the longest here
- Rated only to 5°C, and Meaco's own data shows 1.95 L/day at 10°C/60%
- The filter is HEPA-type; Meaco publishes no filter grade or test standard
- RRP sits above the EcoAir and Pro Breeze compressor units
Don't buy if the room is an unheated garage, conservatory or caravan — the desiccant EcoAir DD1 Simple MK3 is rated to 1°C and holds its output in the cold.
EcoAir DD1 Simple MK3 Desiccant Dehumidifier
Who it's for: The best-value way to dry a cold garage, conservatory or caravan.
The same cold-space capability as the Meaco DD8L Pro — desiccant, rated to 1°C, three-year warranty — for meaningfully less 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.
- 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
- 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
Don't buy if you want digital control and a readout — the Pro Breeze 12L has an automatic humidity sensor and display, though only for heated rooms.
Meaco DD8L Pro Desiccant Dehumidifier
Who it's for: Unheated garages, workshops and caravans where a compressor unit gives up.
The strongest cold-weather performer here, and Meaco substantiates it with dual-condition data: 7.97 L/day at 20°C/60% and still 6.89 L/day at 10°C/60%, a loss of about 14% where compressor units fall away sharply. Rated down to 1°C with a three-year warranty. You pay for that — it is the dearest unit on this page — and at 50 dB on speed 3 it is not something to sleep near.
- Only about 14% output lost from 20°C to 10°C, on Meaco's own figures
- Rated down to 1°C — genuinely suited to an unheated space
- Three-year warranty
- 50 dB on speed 3 is too loud for a bedroom; the quiet 40 dB setting costs output
- The most expensive unit here, with little discounting available
- Includes an ioniser, but Meaco publishes no test data or standard for its antibacterial claim
Don't buy if you're drying a heated living space — the quieter, cheaper Meaco Arete One 12L does that job better for the money.
EcoAir DC12 MK3 Compact Dehumidifier
Who it's for: A cheap, compact compressor unit for a heated room.
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.
- The cheapest full-size unit here, at roughly £129–£140
- Publishes its power draw: 210W low, 240W high
- 39 dB(A) from a genuinely compact body
- 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
Don't buy if the space drops below 15°C — EcoAir's own DD1 Simple MK3 is rated to 1°C for broadly similar money.
Russell Hobbs RHDH2002 20 Litre/Day Dehumidifier
Who it's for: Drying out a larger or wetter heated space, or a room after a leak.
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.
- 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
- Around £155–£190, comfortably under the desiccant units
- 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
Don't buy 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.
Who it's for: A heated room where you want automatic humidity control and a display.
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.
- 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
- 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
Don't buy if the space is unheated — a desiccant unit such as the EcoAir DD1 Simple MK3 is the right tool for a cold room.
Pro Breeze 500ml Premium Mini Dehumidifier
Who it's for: A wardrobe, cupboard or small enclosed cabin — not a room.
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.
- £39.99 and 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
- 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
Don't buy 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.

Common questions
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 and Meaco DD8L Pro are 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 the Meaco DD8L Pro are rated down to 1°C. The compressor units are not: the EcoAir DC12 MK3 is rated from 15°C, the Meaco Arete One 12L and Pro Breeze 12L 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. Damp and mould in homes is taken seriously in UK government and NHS guidance, and the consistent advice is 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. Others are not: the Meaco DD8L Pro reaches 50 dB on speed 3 and the Russell Hobbs RHDH2002 is stated at 47.5 dB, the loudest here. 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.
