Compact and affordable, this Costway 15L/day dehumidifier UK pick targets everyday damp in smaller rooms up to 20m² – think bedrooms, box rooms, studies and small flats. It removes up to 15 litres of moisture a day (at 35°C, 90% RH), enough to clear morning condensation, dry washing and discourage black mould in tighter spaces. With just 210W of power it's one of the cheapest in the range to run, costing around 5-6p per hour at 26p/kWh. At ≤45dB with a dedicated sleep mode it's quiet enough to leave running overnight in a bedroom. Four working modes and two fan speeds let you tailor drying, and a smart touch panel with a clear LED display keeps control simple. The 2.5L tank can be emptied by hand – with a water-full alarm so it never overflows – or you can fit the included drain hose for continuous drainage. Family-friendly touches include a 24-hour timer, child lock and auto-defrost, while four universal wheels make the 9.5kg body easy to wheel between rooms. In the box: the dehumidifier, drain hose and instruction manual. As a compressor unit it performs best in warmer, humid rooms.
