Pro Breeze 12L/Day Dehumidifier with Automatic Humidity Sensor
The best-value small-to-mid dehumidifier on Amazon.co.uk — a genuine Which? Best Buy winner with an unusually large, consistently positive review base, at a price well below the equivalent 20L models on this site.
Devola DV12L Low Energy Dehumidifier
The best-value small dehumidifier on the market right now for a single room or a flat — a genuine Which? award winner that costs less to buy and run than almost anything else in its class, without cutting corners on the basics.
NETTA 12L Dehumidifier
A low-energy 12 litre compressor dehumidifier with a humidistat, timer and drain tube at a budget price, best for a hallway, bathroom or box room where capacity and running cost matter more than silence.
Pro Breeze 500ml Premium Mini Dehumidifier
The best budget dehumidifier for a small bathroom, wardrobe or caravan — not a replacement for a full-size unit, but excellent value for light, localised condensation control.
STARWAX Moisture Absorber Box 25 m² with 500g Tablet
A tidy, silent absorber for light condensation in a bedroom, wardrobe or small room. It is good value upfront, but it is a prevention tool, not a substitute for an electric dehumidifier in a properly damp home.

Best dehumidifier UK under £100 — what's the catch?
Under £100 you're almost always looking at a Peltier mini unit rather than a compressor model — extraction rates around 250-500ml a day rather than 12-20 litres. That's genuinely useful for a small bathroom, wardrobe or caravan, but won't touch a damp bedroom or dry laundry. If your problem is genuine room-wide damp, it's worth saving for a compressor unit rather than buying a budget model that won't solve it.
