LORVYN HEPA Air Purifier Large Room 

REAL AIRFLOW FOR ROOMS THAT ASK MORE: AIR480 delivers a factory-tested 329 CFM / 560 m³/h Smoke CADR with 43W rated power. In a 510 sq ft room with an 8 ft ceiling, that equals about 4.8 room-air changes per hour, and circulates air in spaces up to 2470 sq ft once per hour—meaningful circulation for living rooms, basements and open spaces where a small purifier can feel outmatched.
