EcoAir DC12 MK3 Compact Dehumidifier review
A cheap, compact compressor unit for a heated room.
By Tom Calder
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
- 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
Who shouldn't buy this
the space drops below 15°C — EcoAir's own DD1 Simple MK3 is rated to 1°C for broadly similar money.
