Why it sits behind the MeacoDry Arete One 20L Dehumidifier and Air Purifier

The MeacoDry Arete One 20L Dehumidifier and Air Purifier (8.4) beats the EcoAir DD1 Classic MK6 Desiccant Dehumidifier (8.2) because it does a little better with the review sites and leaves owners a little happier. The EcoAir DD1 Classic MK6 Desiccant Dehumidifier is the newer design, but not by enough to close the gap.

About the EcoAir DD1 Classic MK6

The DD1 Classic MK6 uses a desiccant rotor, not a compressor, to pull moisture from the air. That is why it keeps working in cold rooms: EcoAir rates it from 1 to 40°C. It removes up to 7.5 litres a day at 20°C and 60% relative humidity and is rated for areas up to 60m².

The unit weighs 6kg, measures 290 × 475 × 175mm and has a carry handle. Noise is listed as 34/46 dB(A), the lower figure being the quiet setting. Power draw is 25W when sampling, 300W on low and 580W on high. One retailer works that out at about 8p an hour on low and 15p an hour on high.

Controls are electronic. It has a laundry mode with turbo, a 2, 4 or 8 hour off timer, overdry protection, auto-restart after a power cut and tilt-over protection. It switches between full power, economy and standby by itself. An ioniser, a silver nano filter and an adjustable louvre are built in. The tank holds 2 litres, with a full alert and automatic shut-off, and a 1m drainage hose is supplied for continuous draining.

What owners report about the EcoAir DD1 Classic MK6

We found little owner feedback for this exact model. The reports we could read come from a small number of Currys owners and a single owner of a refurbished unit.

Owners say it dries laundry faster than hanging it up and pulls out a lot of moisture quickly. One described the running sound as a steady hum they found pleasant, and the refurbished unit's owner rated it as quiet and easy to move. Another owner found it noisier than other dehumidifiers they had tried.

The complaints are practical. The small tank needs emptying often, and one owner could not find instructions for taking out the filter to clean or replace it. Nothing we found says how the unit holds up after a year or more.

Who the EcoAir DD1 Classic MK6 suits

Buy it for a bedroom, boat, garage, conservatory or any cool space where a compressor model slows down. It also suits drying washing, and the 6kg weight makes it easy to move between rooms. If the tank is a nuisance, the included hose lets it drain continuously.

Look elsewhere if you need to clear a large, warm, very damp home. The 12L and 20L compressor models remove more in a warm room, and a desiccant unit gives off warmth as it runs. For a bigger desiccant machine, the Meaco DD8L Pro is the one to compare. For a larger tank with a quiet bedroom focus, the Pro Breeze OmniDry 12L is worth a look.

How we score it

Every score here comes from our ranking model; no editor sets the order. Most of each score is what the review sites say: the scores their own reviews give each model, and whether their best-of lists name it. For this guide we read Expert Reviews, Ideal Home, T3 and Woman & Home. The rest is how happy owners are, held back where few owners have rated a product, and how new it is. Value for money earns its own badge rather than a higher place. We compared 22 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in November 2026.
