Blueair 503 HepaSilent Air-Purification System

Perfect for larger rooms, up to 580 square feet, the Blueair 503 air purifier uses superior HEPASilent technology to capture 99.97% of harmful particles such as dust, pollen, and bacteria, down to 0.1 microns in size. Uses both electrostatic and mechanical filtration to deliver clean air efficiently. The Blueair 503 is independently tested and certified by the Association of Home Appliance Manufacturers (AHAM) for a Clean Air Delivery Rate (CADR) of 375 cubic feet per minute for smoke, dust, and pollen, at five air changes an hour. Utilizing SurroundAirTM technology, the 503 takes in air from three sides, releasing clean air from the top and sides, reducing draft and maximizing clean air delivery. Easily change filters from the top of the unit and keep track of filter changes with the included magnetic filter timer. A trusted air purifier, the 503 was tested alongside 22 other air purifiers by The Consumer Rights Protection Commission of Shanghai and rated the best in performance for removal of fine particles (PM2.5) and formaldehyde.
