Blueair 503SS


Blueair is the system for people living with allergies, asthma, or other respiratory conditions, or for anyone who wants cleaner, more breathable air. The 503 effectively purifies air in rooms as large as 550 square feet. Using patented two-stage HEPASilent" technology, it captures 99.97% of the tiniest .1 micron particles on level one, including allergy-provoking pollen grains, dust mites, mold spores and pet dander particles.

Blueair's efficient SurroundAir" vent system delivers exceptional air exchange (up to 500 cubic feet per minute) without annoying drafts, performance that earned the 503 Best of Class ranking in independent AHAM testing of Clean Air Delivery Rate.

Easy maintenance: simply open the unit's lid, lift out and drop in filters every 6 months. Choose the optional SmokeStop Filter Kit for better protection from smoke and other airborne gases.
