Abstract
A housing mounted to the ductwork of a hot air heating system or a central air conditioning system includes a pressure differential switch to sense the forced air flow in actuating a spray dispenser to discharge a freshening, deodorizing and/or disinfecting spray through a nozzle and provided hose into the ductwork, for a duration and at a repetition rate predetermined in accordance with the cleansing results desired.
