BlueAir is the system for people with allergies, asthma, other respiratory conditions, or for anyone who wants cleaner, more breathable air. The Blueair 501/510B effectively purifies air in rooms as large as 620 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 501/510B Best of Class ranking in independent AHAM testing of Clean Air Delivery Rate.
Value-adding features include a 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.
