If you want a BlueAir Air Purifier at an affordable price, the factory refurbished units are a great choice. BlueAir reconditions the units under strict factory specifications and assures BlueAir quality by replacing faulty parts with new, genuine BlueAir components. These units are backed by the standard BlueAir 10-Year Warranty and are in 100% working condition.  Units are less than two years old, and are thoroughly inspected by BlueAir.

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 620 sq. ft. Using patented 2-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 450 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.
