12L Ultra-quiet, Portable, Electric Dehumidifier with 3 Modes

If noise is your priority, this Costway 12 L/day ultra-quiet model is one of the calmest options in the small dehumidifier UK category, running at just ≤36 dB, hushed enough for a bedroom, nursery or home office where you barely notice it. It removes up to 12 litres of moisture per day (at 30°C, 80% RH) and is sized for small to medium rooms of around 12 m², so it is aimed at bedrooms, en-suites and studies rather than whole houses. The low-energy 185 W motor sips electricity, costing only about 5p per hour at 26p/kWh, which makes day-and-night running genuinely affordable. You can set target humidity from 80% down to 30% to keep condensation, window damp and black mould at bay, and a washable dust filter traps airborne particles for cleaner air. Coloured humidity indicator lights show conditions at a glance, and a childproof lock keeps settings safe around little ones. The simple control panel handles modes, fan speed and timer, while the 2 L tank suits its compact size; a 100 cm hose lets you switch to continuous drainage when needed. In the box you get the dehumidifier, drain hose and instruction manual, ready to dry out a damp bedroom quietly.
