A forced air furnace air freshener attached to a cold air return duct thereof. A pair of vertically spaced openings are provided in a wall of the duct. A basket has its lid mounted on the outside of such wall, which lid carries a scent block. The hinged main portion of the gasket is normally closed so that air flowing through the cold air duct is by-passed through said openings and is scented by said scent block.
