Experience the crisp feeling of cleaner air brought to you by the model that made Blueair a world leader in air purifier design and technology.

Although this unit is designed to clear the air in mid-sized rooms, there’s nothing middle of the road about the Blueair 403. Ingeniously designed and brilliantly engineered, the Blueair 403 is based on the absolute original Blueair air purifier first tested at the prestigious Karolinska University Hospital in Stockholm over a decade ago.

The Blueair 403 continues to deliver outstanding performance that has withstood the test of time. Using patented HEPASilent™ technology, it captures 99.97% of the tiniest 0.1 micron particles on level one, including allergy-provoking pollen grains, dust mites, mold spores and pet dander particles.

Design

The union of visually pleasing form and effective function is a hallmark of Swedish design, and Blueair is no exception. The Blueair 403 is designed for maximum performance in mid-sized rooms. Available in white/dark grey, it suits your distinct style of living.

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.
