ABSTRACT:
Apparatus and methods for deodorizing and/or freshening the air are disclosed. In one non-limiting embodiment, the apparatus includes one or more passive members and an air moving member. The passive member can be detachable from the air moving member and used separately as a passive filter member, if it contains a deodorizing substance, or as a passive emitting member, if it contains a substance to be emitted into the air. Numerous combinations of passive filter members and passive emitting members can be used with the air moving member, or as stand-alone members in the described methods. In other non-limiting embodiments, devices can be provided that both deodorize and emit substances into the air. Kits are also provided. The substances to be emitted may be arranged in various ways to improve the amount of exposed surface area of the substance to be emitted. Intensity controlling mechanisms are also provided.
