The Blueair 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 0.1 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 units Best of Class ranking in independent testing of Clean Air Delivery Rates. The Blueair 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.

Superior Quality - 10-Year Warranty

Blueair is designed, engineered and built for people who expect the very best and don't want to compromise on health, design or function. The Blueair system housing is made of galvanized steel, rather than less durable plastic. The fan and blower are manufactured by EBM, a maker of telecom and medical equipment. Blueair systems offer an exceptionally long product life and carry a 10-year limited warranty.

Cleans Air Quietly

Sophisticated materials and precision engineering allow Blueair 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, Blueair'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 Blueair 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.

SurroundAir

Instead of discharging a windy stream of filtered air, the Blueair 501 diffuses air gently through an area six times greater than the average air cleaner. Operating on its lowest setting, Blueair produces virtually no noticeable draft, while still providing an exceptional air exchange rate. Blueair's 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.

Energy Efficient

Blueair's low power usage means you can run the 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 light bulb: only 15 watts on low to 95 watts on high.

Easy to Use and Maintain

Plug it in, select the speed setting, and forget it. Blueair works so quietly, at first you may find yourself wondering if it's turned on. Just check the bright blue power on light. Blueair filters require no weekly additives or filter washing. The grills and powder-coated steel exterior are easy to wipe clean, and won't pick up grime and oily stains the way plastics can. When the filter needs to be replaced (every six months), just open the lid, lift out the old filters and drop the new ones in. No screws, hooks or tools and less than one minute of your time are required. Used filters are 100% recyclable, and release no toxins into landfills or the air.
