Abstract: Described is an air and surface purifying device having a purifying cell structured for maximizing the realized photocatalytic reaction at a photocatalytic surface without using an additional ultraviolet bulb. The purifying cell positions at least three photocatalytic surfaces about a single ultraviolet bulb such that the photocatalytic surfaces substantially encompass the ultraviolet bulb and are saturated by ultraviolet light radiating from the ultraviolet bulb. Because the photocatalytic surfaces are saturated, the potential photocatalytic reaction at the photocatalytic surfaces is fully realized. Stated differently, the realized photocatalytic reaction is maximized. Because the purifying cell maximizes the realized photocatalytic reaction, the purifying cell maximizes the purifying capacity of the photocatalytic surface and, thus, the purifying cell itself.

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.

Abstract: A portable air purifier for purifying air in selected occupied spaces, comprising a base for attaching to a support in the space, a housing pivotally mounted to the base, a fan mounted within the housing and having an air inlet and an air outlet for communicating air through the housing and at least one air treatment device supported in the housing for acting upon air communicated by the fan.
