Blueair - 403 Air Purification System (HEPA)

Replacement filters available for the Blueair 403 include: Particle Filter and the  Smokestop Filter.

The 403 effectively purifies air in rooms as large as 365 square feet. Using patented two-stage 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.

This same filter technology earned the larger Blueair units Best of Class ranking in independent testing of Clean Air Delivery Rates. The 403 provides comparable performance for mid-sized rooms.

Value-added features include quiet operation, low energy use, galvanized steel construction and easy maintenance: simply open the side, slide out used filters and drop in replacements every 6 months.

The Blueair 403 features a limited 10 year parts and labor warranty.
