Contents
Every figure below comes from the maker's own product page, read on November 14, 2026, or from the B&Q listing for the two brands whose UK sites we could not read. We have not tested these dehumidifiers. Our picks above follow written rules: for each need, the cheapest model in stock that meets the condition, or the lowest published figure.
Read this before comparing litres a day
The litres a day in a model's name is measured in a warm, very humid test room. Meaco says so: its Arete One 10L removes 10 litres "at 30°C and 80% RH" and 6 litres at 27°C and 60%, and its own performance table gives 4.34 litres at 20°C and 60%. EcoAir rates its desiccant models at 20°C and 60%, which is why a 7.5-litre EcoAir is not a smaller machine than a 10-litre compressor model in a cool house. Pro Breeze, Ebac, Princess and Russell Hobbs do not publish their conditions. We print each figure with its conditions and never convert one into another. More on 12L vs 20L.
All 47 models
Sorted by type, then litres a day as printed, then price. Cost per hour = published watts × 26.32p per kWh [calc]; for EcoAir desiccants, the high setting.

How we compare: criteria, sources and dates
How the picks are made
- Cheapest 10 L+ compressor with a laundry mode: the lowest price among models in stock, compressor type, 10 litres a day or more as printed, with a laundry mode named on the product page.
- Lowest watts at 10 L/day or more: the lowest published power among compressor models of 10 litres a day or more in stock; a tie goes to the cheaper one.
- Quietest published figure: the lowest "from" noise figure among the same models. Makers do not publish how they measure it, so treat a 1 or 2 dB gap as no gap.
- Cheapest 20 L+ and cheapest desiccant: the lowest price in stock meeting that condition.
Commission plays no part: at the time of writing, no brand's affiliate programme has accepted this site, and the links carry no tracking.
Head to head
- Meaco vs Ebac: the two British makers, watts and prices side by side.
- Meaco vs Pro Breeze: the same stated sizes, a price gap and what you get for it.
- Compressor vs desiccant: watts against cold-room performance.
- 12L vs 20L: what the extra litres cost to buy and to run.

Frequently asked questions
Which dehumidifier is cheapest to run?
Per hour, the Meaco Arete One 6L (101 W, 2.7p an hour at 26.32p per kWh). At 10 litres a day or more, the Meaco Arete One 10L and 12L (151 W, 4.0p an hour) [calc]. Running cost also depends on how long the compressor runs, which a humidistat shortens.
Are litres a day comparable between brands?
No. Meaco publishes its name plate figure at 30°C and 80% relative humidity and a second figure at 27°C or 20°C and 60%; EcoAir publishes its desiccant models at 20°C and 60%; Pro Breeze, Ebac, Princess and Russell Hobbs do not say. A Meaco 10L at 20°C and 60% is rated 4.34 litres a day by Meaco itself.
Why are some prices from B&Q?
When B&Q (diy.com) listed the same model, matched by barcode or exact name, for less than the brand's own store, or when the brand's store showed it out of stock, the button goes to the cheaper seller in stock. Both prices are shown on each card.

- Meaco vs EbacTwo British brands, same stated sizes. Meaco publishes more numbers and quieter figures; Ebac publishes a lower working temperature and sells on its Smart Control.
- Meaco vs Pro BreezePro Breeze is cheaper to buy; Meaco's Arete One draws fewer watts at 12 and 20 litres. We worked out how many winters the difference takes to even out.
- Compressor vs desiccantA desiccant model draws two to four times the watts of a compressor model of similar size, but keeps working near freezing. Where the line falls, from the makers' own figures.
- 12L vs 20LThe number on the box is measured in a hot, very humid test room. In a heated UK home a "12L" removes about 5 litres and a "20L" about 8.5, by Meaco's own figures.
- Drying clothes in a flatIn a flat, the washing is often the biggest source of moisture in winter. What to look for on the spec sheet, and what a load costs to dry.
- Quietest for a bedroomIs there such a thing as a silent dehumidifier? Not on paper: the lowest figure any maker publishes in our list is 32 dB, on the quietest setting.
- Cost per hourWatts ÷ 1,000 × your unit rate. Here is that sum for every model we found that publishes its watts, at the Ofgem cap rate for October to December 2026.
- Run all night?Leaving it on overnight is a question of noise, cost and control. Eight hours flat out cost 32p to 42p for the ten quietest compressor models of 10 litres or more; a humidistat or a timer cuts that.
- Cold room or garageBelow about 15°C a compressor dehumidifier removes far less water. The makers' own tables show how much less, and which models are rated down to 1°C.
