Product Overview

The 501 Blueair Air Purifier is the system for people living with allergies, asthma, or other respiratory conditions, or for anyone who wants cleaner, more breathable air. This filter effectively purifies air in rooms as large as 550 square feet. Using patented two-stage HEPASilent™ technology, the 501 captures 99.97% of the tiniest .1 micron particles, including allergy-provoking pollen grains, dust mites, mold spores and pet dander particles.

Our efficient SurroundAir™ vent system delivers exceptional air exchange (up to 500 cubic feet per minute) without annoying drafts, performance that earned this purifier the Best of Class ranking in independent AHAM testing of Clean Air Delivery Rate.

Easy maintenance: This unit requires replacement of three filters every six months: simply open the side, slide out the used filters and drop in replacement filters. Choose the optional SmokeStop Filter Kit for better protection from smoke and other airborne gases.

Cleans Air Quietly

Sophisticated materials and precision engineering allow this purifier 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, the 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 501 diffuses air gently through an area six times greater than the average air cleaner. Operating on its lowest setting, Blueair air purifier 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

Phenomenally 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 lightbulb: only 35 watts on low to 90 watts on high.
