Design
The union of visually pleasing form and effective function is a hallmark of Swedish design, and Blueair is no exception. The Blueair 402 is designed for maximum performance in mid-sized rooms.
Technology
Blueair’s patented HEPASilent technology combines the best features of electrostatic and mechanical filter technology to enable the delivery of more clean air at a faster rate with less noise. Phenomenally low power usage minimizes energy consumption. Plus Blueair air purifiers actually reduce the levels of ozone in indoor air.
How it works
Air is drawn into the unit via an ultra-quiet fan. 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.
