Abstract
An apparatus and method for treating air. A housing can enclose a heating zone and an oxidizing zone positioned downstream of the heating zone with respect to a flow direction of the air being treated. A catalyst in the oxidizing zone oxidizes contaminants from the air, and an air mover positioned is configured to move air from an air inlet through the housing to an air outlet. An air treatment cycle can include an air cleaning mode at a high air flow and a self-cleaning mode at a lower air flow. A heater is operated during the self cleaning mode to oxidize contaminants that on the catalyst from the air cleaning mode.
