Diagram On How It Works


Air is drawn into the unit via an ultra-quiet fan from one side of the unit. Airborne particles pass through an ion chamber and are charged to ensure that they adhere effortlessly to Blueair’ s progressive three-stage filter. Cleaned air that is free of impurities is recirculated into the room.
