The NEW Blueair 503 Air Purifier effectively purifies air in rooms as large as 580 sq. ft. 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 using patented 2-Stage HEPASilent™ technology and 3-stage progressive filter structure.

The 503’s efficient SurroundAir™ vent system delivers exceptional air exchange (up to 450 cu. ft. per min.) without annoying drafts. This same performance and filter technology earned earlier BlueAir units Best of Class ranking in independent AHAM testing of Clean Air Delivery Rates. The 503 provides comparable performance for large-sized rooms.
Value-adding features include quiet operation, low energy use, galvanized steel construction, a 5-year warranty, and a convenient Change Filter Indicator that reminds you to change your filters every six months.
