The Pro Breeze 12L Dehumidifier with built-in humidistat is a small-but-mighty dehumidifier that keeps your home fresh and dry while sipping power, clearing window condensation, damp walls and stubborn black mould. Removing up to 12 litres a day, it suits medium-sized homes and flats where moisture is a recurring problem. Its standout feature is the built-in humidistat, which lets you set and monitor a target humidity (40 to 60% is recommended), so the unit only works when it needs to rather than running constantly, keeping the cost as low as 5p an hour. It's also notably quiet, described as less intrusive than a quiet dishwasher, so it's comfortable to run in living spaces and won't dominate a room. A 1.8L tank needs around 16.6% less frequent emptying than some rival brands, a small convenience that adds up over weeks of use. As a compressor dehumidifier it performs best at normal room temperatures, drawing plenty of moisture while staying energy-efficient. Independent recognition backs it up: it was named a Which? Great Value Winner in January 2025. At 9.6kg it's easy to move between rooms as damp shifts around the house. Quiet, controllable and genuinely cheap to run, it's a dependable everyday defence against damp.

12L Dehumidifier with Built-in Humidistat — FAQs
How much does the Pro Breeze 12L dehumidifier cost to run per hour?
As little as 5p an hour. Because the built-in humidistat lets it switch off once your target humidity is reached, it only runs when needed, which keeps the running cost low.
What does the built-in humidistat do?
It lets you set and monitor a target relative humidity, with 40 to 60% recommended. The dehumidifier then maintains that level automatically, running only when humidity rises above your setting, which saves power and prevents over-drying.
Is the Pro Breeze 12L dehumidifier quiet?
Yes. It's described as less intrusive than a quiet dishwasher, so it's comfortable to run in living spaces and bedrooms without dominating the room. It was named a Which? Great Value Winner in January 2025.
What size home does this 12L dehumidifier suit?
With up to 12 litres a day of extraction it suits medium-sized homes and flats with recurring condensation, damp or mould. For larger 3 to 4-bedroom houses with heavy moisture, a 20-litre model is a better fit.
