The Blueair 402 is the system for people living with allergies, asthma, or
other respiratory conditions, or for anyone who wants cleaner, more breathable
air. This unit 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
Cleans Air Quietly
Sophisticated materials and precision engineering allow the filter to clean
indoor air without the noise associated with less advanced units. On the lowest
setting, the units emit no more sound than a desktop computer. To achieve
exceptionally quiet operation, this air cleaner's patented HEPASilent™ filter
technology traps particles two ways: with mechanical and electrostatic filters.
This combination creates a filter system through which air flows freely. Most
air cleaners require a powerful, noisy fan to pull air through densely packed
filters. Since air passes easily through the filter media, the fan doesn't have
to work as hard or as loud. Even the housing is designed with quiet operation in
mind, replacing sound-sonant plastic with noise-muffling steel.
Surround Air
Instead of discharging a windy stream of filtered air, the Blueair 402
diffuses air gently through an area six times greater than the average air
cleaner of the same class. Operating on its lowest setting, the 402 produces
virtually no noticeable draft, while still providing an exceptional air exchange
rate. The SurroundAir™ system achieves peak performance without annoying drafts
by drawing in dirty air from the sides and bottom, moving it through a less
dense filter media, and releasing clean, filtered air from the sides and top.
Low Energy Cost
A phenomenally low power usage means that you can run this air cleaning
system 24/7 without a jump in electricity consumption. In fact, it costs about
the same to clean the air in your home as it does to power a single lightbulb:
only 15 watts on low to 80 watts on high.
10-Year Warranty
Blueair warrants that your air purifier will be free from defects in material
or workmanship for a period of ten (10) years from the date of purchase provided
that you have completed and returned your warranty registration to Blueair, and

reimburse any shipping charges. After 30 days, Blueair's obligation and
liability under this Limited Warranty is limited to repairing or replacing (at
its sole discretion) the defective unit and paying the freight cost of returning
the unit to you. The Limited Warranty does not cover replacement filters.
