BlueAir is the system for people with allergies, asthma, other respiratory conditions, or for anyone who wants cleaner, more breathable air. The 501 effectively purifies air in rooms as large as 580 sq. ft. Using patented two-stage HEPASilent™ Technology and the 3-stage progressive filter structure, it captures 99.97% of the tiniest 0.1 micron particles on Speed One, including allergy-provoking pollen, dust mites, mold spores and pet dander.

Our efficient SurroundAir™ vent system delivers exceptional air exchange (up to 500 cu. ft. per min.) without annoying drafts. This performance earned the 501 Best of Class ranking in independent AHAM testing of Clean Air Delivery Rate.

Value-adding features include a 10-year warranty and easy maintenance: simply open the unit's lid, lift out and drop in filters every six months. Choose the optional SmokeStop Filter Kit for better protection from smoke and other airborne gases.
