The NEW Blueair 403 Air Purifier effectively purifies air in rooms as large as 365 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.
This same filter technology earned the larger BlueAir units Best of Class ranking in independent AHAM testing of Clean Air Delivery Rates. The 403 provides comparable performance for small-sized rooms.
Value-adding features include quiet operation, low energy use, galvanized steel construction, a 3-year warranty, and a convenient Change Filter Indicator that reminds you to change your filters every six months.
