Blueair 402 HEPASilent™ Medium Room Air Purifier
365 Sq. Ft. Coverage
The new Blueair 402 in-room air purifier is the only air purifier with its room capacity to use HEPASilent™ technology, a combination of the best features of electrostatic and mechanical filter technology that allows delivery of more clean air, at a faster rate, with less noise.
Particles that mechanical filtration alone might miss are captured by the electrostatic component of Blueair's HEPASilent™ system. HEPASilent technology filters out 99.97% of particles at 0.1 micron, when operating at its lowest speed!
The 402 is among the highest energy efficient and quietest operating air purifiers in its class, with a room capacity of 365 sq. ft. The unit is available in silver and white.
Blueair is the system for people living with allergies, asthma, or other respiratory conditions, or for anyone who wants cleaner, more breathable air.
This same filter technology earned the larger Blueair units 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, galvanized steel construction and easy maintenance: simply open the side, slide out used filters and drop in replacements every 6 months.
