This Costway 24 L/day dehumidifier is an efficient, mid-size choice in the dehumidifier UK range, removing up to 24 litres of moisture per day (at 35°C, 90% RH) and covering spaces up to 30 m². That makes it a reliable pick for basements, large bedrooms, lounges and utility rooms where damp, condensation and black mould take hold. Its three modes set it apart: Dehumidify for general humidity control, Continuous for non-stop drying, and a dedicated Dry Clothes mode for drying laundry indoors without a tumble dryer, a real winter money-saver. Power ranges from 345 W to 415 W depending on conditions, so at 26p/kWh expect roughly 9p to 11p per hour, and as a compressor unit it cycles off once your set humidity (30% to 80%) is reached, keeping daily cost low. Both auto drainage (via the included 1 m hose) and manual emptying of the 2.5 L tank are supported, so you can run it hands-free or tip it out as you go. An easy-to-read LED display, a 24-hour timer and a child lock add convenience, scheduling and family safety. At 13 kg it is straightforward to move between rooms. In the box you get the dehumidifier, drain hose and instruction manual.
