Devola DV12L Low Energy Dehumidifier Review: price, specs and verdict (2026)

For a bedroom or box room with condensation on the windows, run the DV12L with the humidistat set to around 50-55%, the level most UK health guidance treats as the ceiling for avoiding dust mites and mould growth. The unit will cycle on and off automatically to hold that target rather than running continuously, which is what keeps the running cost down to roughly 5p an hour.

For drying laundry, switch to Laundry mode and place the unit next to a clothes airer with the door closed — reviewers consistently report a full wash load drying in under a day, some in as little as five or six hours in a small closed room. Because the tank is only 2 litres, expect to empty it once during a laundry-drying session on a full load.

In a static caravan, garage or unheated conservatory, this is one of the few compressor dehumidifiers in its price bracket rated to keep working down to 5°C — several verified buyers specifically bought it for exactly this use case (a garage recording studio and a static caravan both feature in genuine owner reviews) and reported it held humidity around 50% even when starting from over 80%.

Best placement is a central spot with a few centimetres of clearance for airflow, on a hard floor rather than carpet if possible, since the tank can drip slightly when removed for emptying.

Devola built its dehumidifier range specifically around the everyday British damp problem — condensation on bedroom windows, a laundry room that never quite dries, a static caravan or box room that smells musty by October. The DV12L is the entry point into that range: a straightforward compressor dehumidifier without the air-purification extras of the flagship DVHA20L, aimed squarely at buyers who want one job done well rather than several done adequately.

That focus shows in the independent recognition it's picked up: a Which? Great Value Award in November 2025 and Good Housekeeping Institute approval for 2026, both awarded on tested performance rather than marketing claims. For a 12-litre unit costing under £150, that combination of independent validation is unusual — most budget dehumidifiers in this price bracket carry no third-party endorsement at all.
