Verdict

The Korona 82100 is a compressor dehumidifier for rooms up to 30 m², with a maximum extraction rate of 20 litres per day, 370 W input, and R290 refrigerant. It has a removable 6.5-litre tank with overflow protection, 30-80% humidity control in 5% steps with a three-colour LED indicator, laundry-drying mode, a washable dust filter, a 24-hour timer, and continuous drainage through the supplied hose. At 14.62 kg it is heavy to carry between floors, and compressor performance can fall or icing can occur in very cold rooms.
