ABSTRACT:
The disclosed apparatus dispenses volatized air freshener compound into the room air forcibly moving the air through a prefilter and a high efficiency filter utilizing a fan disposed in the space therebetween. A container of volatile air freshener liquid or gel is positioned in a location such that the air drawn through the prefilter will pass across the top of the container. The container is provided with a lid mounted for movement to open and close the container, the lid being connected to and operable by a control such as a timing mechanism to adjustably regulate the amount of volatized air freshener compound which is permitted to escape into the air passing through the air filter, or the container can be kept totally closed and thus inoperative.
