The W200 air washer merges air purification and humidification into one single device. Stretched over a rotating drum, a 3D fabric first actively moves through water and then through the airflow. This cleans and humidifies the room air at the same time. The water tray can be conveniently filled, while all water-bearing parts can be disassembled in a few simple steps for cleaning in a dishwasher. When there is no more water in the device, it switches off automatically.
