A scented material is impregnated into the body material and is constructed to melt and release a scent when exposed to heat at a predetermined temperature for aromatherapy, insect repellant, wild life attractant, medicinal use, deodorant and odor control, perfume release, or any other desired or suitable purpose. The body material does not melt at the predetermined temperature. ## Claims ### Claim 1 A scented wafer for emitting a scent to a surrounding open environment, said scented wafer being uncovered to present a large surface area for emission of scent to the surrounding open environment, and comprising a body material formed of a heat-resistant fibrous material having a predetermined porosity resulting from a selected denier and length of fibers; and a scented material impregnated into the body material and constructed to melt and release a scent when exposed to heat of a predetermined temperature that exceeds the temperature of the surrounding open environment and a melting point of the scented material; wherein the body material retains structural integrity and does not melt at the predetermined temperature to facilitate the reuse or replacement of the wafer, and the body is formed with numerous edges and grooves to create a large surface area for emission of the scented material when heated and melted. ### Claim 2 (depends on 1) The scented wafer of claim 1 wherein the body material is selected from a group comprising nonwoven, woven, meltblown, spunbond, extruded thermal bonded, extruded chemical bonded, resin bonded nonwovens, pulp and cellulose composite materials. ### Claim 3 (depends on 2) The scented wafer of claim 2 wherein the body material is comprised of a natural or synthetic blend and varied denier of fibers. ### Claim 4 (depends on 1) The scented wafer of claim 1 wherein the fibers comprise a synthetic material. ### Claim 5 (depends on 1) The scented wafer of claim 1 wherein the fibers comprise a natural material. ### Claim 6 (depends on 1) The scented wafer of claim 1 wherein the fibers comprise glass. ### Claim 7 (depends on 1) The scented wafer of claim 1 wherein the fibers comprise a pulp based material. ### Claim 8 (depends on 1) The scented wafer of claim 1 wherein the fibers comprise organic starch derivative material. ### Claim 9 (depends on 1) The scented wafer of claim 1 wherein the fibers are polyester with a high degree of moisture regain and temperature and chemical resistivity. ### Claim 10 (depends on 1) The scented wafer of claim 1 wherein the scented material is wax. ### Claim 11 (depends on 1) The scented wafer of claim 1 wherein the fibers are of a fine structure and small size so as to create a tight structure in the body material for a slow release of scented material therefrom when it is heated and melted. ### Claim 12 (depends on 1) The scented wafer of claim 1 wherein the fibers are of a coarse structure and large size so as to create a coarse and open structure in the body material for a quick release of scented material therefrom when it is heated and melted. ### Claim 13 (depends on 1) The scented wafer of claim 1 wherein the fibers range from 0.5 denier to 25 denier and from lengths of 1/16 inch to 10 inches. ### Claim 14 (depends on 1) The scented wafer of claim 1 wherein the body material is felt. ### Claim 15 (depends on 1) The scented wafer of claim 1 wherein the body material will harden when cooled so that it can be reused when it still contains scented material impregnated therein.
