| Blueair is the system for people living with allergies, asthma, or
other respiratory conditions, or for anyone who wants cleaner, more
breathable air. The 402 effectively purifies air in rooms as large
as 365 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. |

This same filter technology earned the larger Blueair 501 Best of Class
ranking in independent testing of Clean Air Delivery Rates. The 402
provides comparable performance for mid-sized rooms.
Value-added features include quiet operation, low energy use, steel
construction and easy maintenance: simply open the side, slide out used
filters and drop in replacements every 6 months
