Superior Quality

Blueair 501 air purifiers are designed, engineered and built for people who expect the very best and don't want to compromise on health, design or function. The Blueair air purifier 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 501 air purifiers 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 air purifier 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-resonant plastic with noise-muffling steel.

Surround Air Technology

Instead of discharging a windy stream of filtered air, the Blueair 501 air purifier 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 Effici

Blueair 501 air purifiers 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 light bulb: only 15 watts on low to 95 watts on high.

Environmentally Aware

Blueair 501air purifiers offer exceptional performance without polluting the environment. Blueair replaces standard triclosan-coated paper or glass filter fibers, which can harm the environment when released into the waste stream, with safer, nontoxic polypropylene. This revolutionary filter media is one of the least harmful plastics, producing only carbon dioxide and water as it decomposes. Because polypropylene is waterproof, the filters naturally resist contamination from bacteria, viruses and mold, without chemical additives or washes. Blueair even uses a special powder coat finish that produces no chemical out gassing.

Award-Winning Swedish Design

The union of visually pleasing form and effective function is a hallmark of Swedish design, and the Blueair 501 is no exception. Its sleek contemporary look has earned Blueair air purifiers one of the most prestigious design awards in Scandinavia, the Excellent Swedish Design award. In fact, the Blueair unit resides in a permanent exhibit at The National Museum in Stockholm. At Blueair, we design air purification systems to meet your home's aesthetic standards without sacrificing performance.
