How HEPASilent Works:

1. Air is drawn into the Blueair 503 system via its ultra-quiet fan.
2. Airborne particles pass through an ion chamber and are electrically charged. This causes them to adhere effortlessly to Blueair's exclusive polypropylene filters.
3. Charged particles are removed in the 3-stage Progressive Filter. Stage 1 captures larger particles like pollen and dust. Stages 2 and 3 filter the smallest particles like cigarette smoke* and exhaust. Together, the encapsulated ion chamber and 3-stage Filtration Process combine to create Blueair's patented HEPASilent technology - delivering maximum airflow with minimum noise.
