Abstract
An air-treating apparatus for dispensing a volatilizable material, such as air freshener fragrance, into the atmosphere of an enclosed area. The apparatus includes a housing and a reservoir of the volatilizable material therein, and also includes a multiple-configured air flow path arrangement which enables air-flow through the apparatus in multiple configurations. The apparatus enables use of the consistent delivery rates of a volatilizable material producing a more consistent delivery rate than normally achieved with such devices.
