Best 5
Five roles, from a small heated flat to a laundry workhorse
Short answer: for most heated UK flats we’d start with the MeacoDry Arete One 12L. The rest are picked by job, not ranked. Litre figures are the maker’s, often at a warm test point.
More 20 L and 16 L options from other brands
If none of the five fits your home, these are the other big compressors we'd look at. Each one suits a slightly different job:
What is missing on purpose
The EcoAir desiccants aren’t in this five because they’re the cold-room answer, not the heated-home default. The Meaco DD8L is Meaco’s desiccant for that same cold-room job, sitting alongside the EcoAir DD1 Simple MK3 rather than in this heated-home list. The Arete Two 12 L isn’t here because it’s the same 12 L class as the Arete One, with an app and a faster fan. The Arete Two 20 L is the same app step-up in the 20 L class. It isn’t a Best 5 swap for the Arete One 20 L. The Arete One 25 L is a step-up from the 20 L, not a different role. The Russell Hobbs mini is a shelf collector, not a house machine.
If you’re deciding between the two 12 L compressors or the two 20 L compressors, the comparison pages are here for that:
If your space is cold or unheated, the EcoAir DD3 Classic MK3 is the larger desiccant review.
Common questions
Is the Best 5 a ranked scoreboard?
No. The order is the job each machine is here to do: small flat, quiet everyday 12 L, laundry / damp-house workhorse, whole home, and value 12 L. Extraction figures are what the maker claims, often at a warm test point.
Which dehumidifier for damp walls or a wet laundry airer?
For a damp house and indoor washing, the Pro Breeze 20L is the laundry / damp workhorse on this list. If you’ve got a quieter heated flat with a modest airer, we’d start with the MeacoDry Arete One 12L. A cold unheated room needs a desiccant, not a bigger compressor. The guide explains that.
Why are Arete Two and the Russell Hobbs mini not in the five?
The Arete Two 12 L is the same 12 L class as the Arete One, with an app and a faster fan, not a different role. The Arete Two 20 L is the same step-up in the 20 L class. That’s the app, the DC motor and higher laundry airflow, not a Best 5 swap for the Arete One 20 L. The Russell Hobbs mini is a shelf collector for a bathroom or wardrobe, not a house machine. The full reviews are under Reviews.
What does it cost to run a dehumidifier?
What it costs you to run comes down to the watts and how long you leave it on. An Arete One 12 L is published at 151 W at 20 °C / 60 % RH, and desiccants draw more (the EcoAir DD1 is 300 W on economy). The guide explains why you’d buy a desiccant for a cold room, not because it’s cheaper in a heated lounge.
Will a dehumidifier help damp walls?
It can, if the wet walls come from the air in the room, like condensation on a cold wall or washing drying indoors. A dehumidifier pulls that water out of the air, but it isn’t a cure for mould or a fix for the wall itself. For a damp heated house, the Pro Breeze 20L is the laundry / damp workhorse on this list. If the room is unheated, you’d want a desiccant, not a bigger compressor.
