Patented HEPASilent™ Filter Technology: While a typical HEPA filter removes 99.97% of particles 0.3 microns or larger, Blueair's HEPASilent filters remove particles as small as 0.1 microns in size. Blueair's unique nontoxic polypropylene filter contains millions of ultra-thin fibers that trap tiny particles as they pass through the pleats. The harmless plastic filters eliminate bacteria, viruses and mold naturally, without chemical additives.

Quietest units in the industry: Blueair delivers more clean air at a faster rate, with less fan noise. Designed throughout with quiet operation in mind, on its lowest setting a Blueair air purifier produces virtually no noticeable draft.

Superior Design: The Blueair system housing is made of galvanized steel, has a phenomenally low power usage, and most systems are backed by a 5-year limited warranty.
