Abstract: A method and apparatus are described for dispersing an air modifying agent (e.g. a fragrance) in air. The air modifying agent and an electrolyte are entrained in a gel-based aqueous reservoir (7), which contacts a pair of electrodes (8, 9) which are +ve and −ve with respect to each other to provide an electrical potential between the electrodes. The electrical potential powers a small motor and fan (13, 14) which disperse the air modifying agent from the surface of the reservoir (7) to the surrounding atmosphere via apertures (16) in a housing (10) of the apparatus. The electrical potential can power additional or alternative electrical devices such as lighting and heating devices, and the arrangement may be such that the extent of exhaustion of the air modifying agent from the reservoir (7) corresponds generally to the extent of exhaustion of electrode (8, 9) activity, whereby the operability of the electrical device indicates the presence of air modifying agent in the reservoir (7).

Abstract: A fragrance extender releases fragrance from a fragrance producing composition over a prolonged interval of time. The fragrance includes a piece of ceramic material of sufficient porosity to permit penetration of the fragrance emitting substance and the carrier liquid therefor. A support structure supports the piece of material relative to a support surface so that the exposed surface area that receives the fragrance emitting substance is at a removed location. A method of retarding the evaporation of a selected fragrance producing composition is also disclosed. The method includes the steps of providing a piece of ceramic material and then contacting a portion of the exposed surface of the ceramic material with the selected composition.
