摘要:
An air freshening device is made from a solution of a polymer and a fragrant material, which is applied to an air permeable substrate. A solid fragrant residue is formed on the substrate. A fragrant material diffuses from the residue for scenting flowing through and about the substrate. An attachment is provided for attaching the substrate to an air filter received in a forced air heating, ventilating, and cooling system.
