Description of Blueair 402 Air Purification System

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

The air purifier's HEPASilent filter technology is geared towards a more environmentally friendly design as well. Its nontoxic polypropylene filter contains millions of ultra-thin fibers that trap tiny particles as they pass through the pleats. One of the least harmful plastics for human health and the environment, polypropylene works without outgassing or shedding irritating microscopic fibers into the air. Because polypropylene is waterproof, the filter resists contamination from bacteria, viruses, and mold naturally, without chemical additives. And as used filters are discarded and decompose, the filter media converts into harmless carbon dioxide and water.

Not only does the unit clean air with environmentally friendly filters, it's HEPASilent filter technology also allows for extremely quiet operation. On the lowest setting, the unit emits no more sound than a desktop computer. With its HEPASilent filter technology, particles are trapped with both mechanical and electrostatic filters so that in combination, the two filters create a filter system through which air flows freely and the fan doesn't have to work so hard. The unit's design is also geared towards quiet operation with its noise-muffling steel housing. Not only quiet, but the air purifier is energy efficient as well, using less power than a 20-watt light bulb, or 80 watts on high.

The air purification system operates efficiently, quietly, as well as inoffensively. Instead of discharging a windy stream of filtered air, the unit diffuses air gently through an area six times greater than the average air cleaner. Its 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. Operating on its lowest setting, the system produces virtually no noticeable draft, while still providing an exceptional air exchange rate.

The air purifier features a sleek, contemporary, Swedish design and is easy to use and maintain. Simply plug it in, select the speed setting, and it is ready to go, with a bright blue power "on" light to show that it's working. The grilles and powder-coated steel exterior are easy to wipe clean, and when the filter needs to be replaced (twice yearly), just open the side, slide out the old filters, and drop the new ones in. This quiet, efficient, easy-to-use air purifier measures 23 by 20 by 11 inches and carries a 10-year warranty. --Catie Unger
