Abstract
An apparatus for treating air includes a housing with an air inlet and an air outlet, the housing enclosing an air treatment zone and an ozone removal zone, wherein the ozone removal zone is positioned downstream of the air treatment zone with respect to a flow direction of the air being treated, an ultraviolet (UV) light source in the air treatment zone configured to generate ozone from the air, wherein the UV light from the UV light source and the ozone generated by the UV light source treat the air in the air treatment zone, catalyst in the ozone removal zone that removes at least a portion of the ozone generated by the UV light source, and an air mover positioned near the air outlet configured to draw the air through the air inlet into the air treatment zone from outside the housing.
