The efficient SurroundAir vent system delivers exceptional air exchange (up to 500 cubic feet per minute) without annoying drafts, performance that earned the Blueair 503 Best of Class ranking in independent AHAM testing of Clean Air Delivery Rate.

Easy maintenance: simply open the unit's lid, lift out and drop in filters every 6 months. Choose the optional SmokeStop Filter Kit for better protection from smoke and other airborne gases.

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 503 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.
