ABSTRACT:
A room deodorizer that relies on the fact that oil and water do not mix and that oil is lighter than water, to the end that water can be used to drive the perfume oils out of a paper matrix or the like by molecular displacement consequently, instead of having a perfume solution moving up a wick, it is provided that water rises from a reservoir by capillary action into an upper portion of a wick which is impregnated with perfume oil, and because of the molecular displacement of the oil by the water, the perfume oil is thereby driven to the surface when it evaporates into the ambient.
