Abstract
An air purifier (10) held in a housing (12, 14) with an ambient air inlet (16) and an air outlet (18) and defining an airflow path therethrough for treating ambient air, a filter (disposed in the airflow path and having an air permeable media for communicating air therethrough while retaining particles carried in the flow of air. A purification device attaches to an intermediate chassis in the airflow path for treating the air moved by a fan (70) into operative engagement with the purification device within the housing and out the air outlet. A controller operates the purification device by sensing an operative status of the purification device.
