The Air Washers humidify and wash the air without the need for filter mats. Specially textured humidification discs turn in the water, which adds moisture to the air. The water acts as a natural filter, which washes the air of impurities (e.g. dust, pollen and particlebound odours). The self-regulating evaporation principle ensures the correct humidity in the room, as the air automatically draws as much moisture as it needs at any given moment. Air Washers can be used all year round and are especially suited for allergy sufferers, due to their natural cleaning principle, without the need for additives.
