Devola 12L/day Low Energy Dehumidifier Review

The Devola 12L Low Energy Dehumidifier is a compressor-based unit specifically marketed towards the UK's damp climate. It is designed to extract up to 12 litres of moisture per day, making it suitable for small to mid-sized houses or flats. Its compact design allows it to be moved between rooms easily, and the inclusion of a dust filter helps improve air quality while protecting the internal components. It positions itself as a 'buy once, use often' appliance for those struggling with window condensation or slow-drying clothes.

In typical UK conditions (around 18-20°C and 60-70% humidity), this unit performs reliably, though users should note that as a compressor model, its efficiency drops in very cold spaces like unheated garages. The laundry mode is particularly effective, noticeably reducing the time clothes spend on a drying rack. Noise levels are impressively low, making it one of the few models in this price bracket that can be used in a hallway overnight without disturbing sleep.

Devola claims running costs of less than 5p per hour based on current UK average energy tariffs (approx. 24.5p/kWh). For a household running the unit 6 hours a day during the four winter months, this equates to roughly £36 a year. By reducing the need to turn up central heating to 'burn off' dampness and eliminating use of a 2500W tumble dryer, many households could see a net saving of £50-£100 per season on their energy bills.

No complex setup required. Simply unbox, let the unit sit upright for 6-12 hours to allow the compressor refrigerant to settle, and plug into a standard UK 3-pin socket.

Expected running costs are approximately 3.5p to 5p per hour depending on the compressor load and local electricity tariffs.
