Best Dehumidifier UK (2026)

As a rule of thumb: 10-12L/day for a flat or 1-3 bedroom house, 20L/day for a 3-5 bedroom house, and 25L+ for larger or particularly damp properties. If you mainly want to dry laundry indoors, size up rather than down.

Compressor units are cheaper to run and best for normal room temperatures (above roughly 15°C). Desiccant units cost more to run but keep working in cold, unheated spaces like garages — below about 10°C a compressor loses most of its effectiveness.

Most UK health guidance recommends keeping indoor humidity between 40-60%, with 50% as a comfortable target that discourages both dust mites and mould growth.

Desiccant models are the right choice for a cold garage, unheated loft or static caravan over winter, since — unlike a compressor — they keep working effectively below about 10°C. Meaco's desiccant range (the DD8L Pro) is the model most commonly recommended by UK reviewers for this use case. We haven't sourced and verified a desiccant model on this site yet — every model compared above is a compressor unit, which is the right type for a normally heated room.

Under £100 you're almost always looking at a compact Peltier unit rather than a compressor — see our dedicated comparison of the best budget dehumidifiers under £100, including the Pro Breeze 500ml, for what that budget can realistically solve.

For damp walls and condensation, prioritise extraction rate — a 20L compressor unit like the Meaco Arete Two clears excess moisture fastest and stops fresh mould forming, though it won't remove mould that's already established on the wall. See our full comparison of the best dehumidifiers for mould and damp.

For a small room, wardrobe or caravan, a compact Peltier unit like the Pro Breeze 500ml is the best mini option — silent, cheap to run, and sized for a single small space rather than a whole room. See our full small dehumidifier comparison.

Which?, the UK's leading independent consumer testing body, has given its Best Buy Dehumidifier award to several Pro Breeze models, including the 20L OmniDry and the 12L/Day — both compared above. A Which? Best Buy is one of the more trustworthy independent UK-specific endorsements a dehumidifier can carry.

Pro Breeze is the strongest value dehumidifier brand in the UK, regularly picking up Which? Best Buy awards and undercutting Meaco on price for comparable extraction rates — the trade-off is a 1-year warranty versus Meaco's 5 years. See our full Pro Breeze 20L OmniDry review.

The Pro Breeze 20L OmniDry (April 2025) and the Pro Breeze 12L/Day have both won the Which? Best Buy Dehumidifier award, recognising strong extraction performance, low noise and good value against competitors tested by Which?.

The Pro Breeze 20L OmniDry WiFi is our top pick from the Pro Breeze range — a Which? Best Buy winner with smart app control, laundry mode and a larger 4L tank than Pro Breeze's smaller models, at a lower price than the equivalent Meaco.
