By securely sealing odor absorbing material (70) in a flexible container (21) formed from a multi-layered sheet material (22, 23), a unique and highly advantageous air freshening and/or deodorizing system (20) is attained. In the preferred embodiment, the odor absorbing material (70) is retained by at least one microporous or permeable membrane (75) to prevent unwanted dispersion of the odor absorbing material (70) into the ambient surroundings, while also controlling the rate of transfer of the ambient air into contact with the odor absorbing material (70). In addition, in the preferred embodiment, the air freshening and/or deodorizing system (20) of this invention employs a small, compact and flexibly moldable container or housing (21) which enables the system (20) to be easily positioned in any desired location, regardless of the size constraints imposed thereon.
