An aroma scent dispersing assembly which selectively meters the fragrance emittance output, varying the concentration of aroma vapor in the discharge air flow is disclosed. The dispersing assembly includes a house having interconnected base members, selectively removable cover, opposite side walls, front and end walls defining an inner compartment with at least the end wall having access openings therethrough. A motor driven forced air fan assembly is arranged in the compartment and includes controls for selectively generating a flow of air from the front wall to discharge through the access openings of the end wall. An aroma dispensing cartridge assembly is arranged in the compartment and has apertures therethrough to expose the interior to the flow of air. A scented vapor emitting source, such as one or more wafers is supported by the aroma dispensing cartridge and is exposed to the flow of air. The aroma dispensing cartridge assembly is constructed for being selectively movable to meter and vary the amount of exposure of the vapor emitting source to the flow of air.
