An air treatment device that is placed in fluid communication with an environment to be treated or an air stream moving about an air handling apparatus, that includes, among other elements, a replenishable and or resealable porous container, which is or which contains a treatment substance. The container is preferably positioned proximate to the air stream by an optional retainer that supports the container by way of one or more attachment devices. The retainer may be formed from a telescopically mated pair of side walls. The attachment device(s) are preferably configured to adjustably and releasably connect the treatment device to the air handling apparatus and equipment. In variations of the preferred configurations, the attachment devices can include magnets, adhesives, hook and loop type fasteners, reconfigurable clips, and posts and ties, and any desired combination thereof. The treatment substances can be any of a wide variety of desired materials, which include, for example, odoriferous, pesticidal, fungicidal, and bacteriocidal substances in forms ranging from scented liquids, solids, and beads to potpourri and odorous powders, granules, and fibrous sheets and materials impregnated or treated with such substances. In modifications of the preferred arrangements, the porous container may be formed from a flexible polymeric sheet material as a pouch, which may also further include a tongue and groove type resealable closure about one side.
