PureDirect dual airflow uses two streams of air without directing the airflow at people in the room. The result of rigorous testing has proven that bi-directional airflow delivers purified air more effectively throughout a room, and in some cases, has been proven to be up to 24% more efficient than traditional air purifiers with vertical airflow.
Smart option available only with the Z-2500 and Z-3500 Smart Air Purifiers, learn more here.
Most purifiers can leave rooms with dead zones. Purifiers that push air out in one direction create areas where little to no air circulates. PureDirect has two separate airflow streams to minimize dead zones.
