Abstract
A replacable cartridge for air-treating apparatus which includes a blower for generating an air stream. The cartridge includes a battery on which a seat in the form of a cap or sleeve having a flange is mounted and with a porous block to be impregnated with a vaporizable air-treating material seated on the flange. The block has peripheral holes in whose surfaces the vaporizable material is absorbed and from which the vapor is released. The holes are unobstructed by the seat. The battery is connected to energize the blower which produces a stream of air to pass over the surfaces of the holes and produce the vapor.
