HEPASilent™ Technology

- Air is drawn into the BlueAir system through our ultra-quiet fan.

- Airborne particles pass through an ion chamber and are electrically charged. This causes them to adhere effortlessly to our exclusive polypropylene filters.

- Charged particles are removed in our Three-Stage Progressive Filter. Stage One captures larger particles like pollen and dust. Stages Two and Three filter out even the smallest particles like cigarette smoke* and exhaust. Together, the encapsulated ion chamber and Three-Stage Filtration Process combine to create BlueAir’s patented HEPASilent™ technology—delivering maximum airflow with minimum noise.

Instead of discharging a windy stream of filtered air, the BlueAir 501 and 601 diffuse air gently through an area six times greater than the average air cleaner. Operating on its lowest setting, the BlueAir 501 and 601 produce virtually no noticeable draft. BlueAir’s SurroundAir™ system achieves peak performance without annoying drafts by drawing in dirty air from the sides and bottom and releasing clean, filtered air from the sides and top.
