An air washer is a 2-in-1 appliance that combines a humidifier and an air purifier. As a humidifier, the air washer increases the air humidity indoors to a pleasant level. The air washer also cleans the air by filtering large particles and pollen from the air.
The technology works by sucking in the room's dry air and passing it over discs turning in water, so that the dry air absorbs moisture. Dirt particles are then washed from the air – they stick to the wet discs and are washed out by the rotation in the water.
An air washer uses the humidification principle of evaporation. Unlike systems that use filter cassettes, the evaporator discs do not need to be exchanged. Most of the air contaminants are filtered in the air washer so it needs to be regularly rinsed out and cleaned. The Stadler Form design air washer Robert ensures clean air at optimal humidity all year round.
