PCT No. PCT/US93/05140 Sec. 371 Date Dec. 2, 1994 Sec. 102(e) Date Dec. 2, 1994 PCT Filed May 28, 1993 PCT Pub. No. WO94/01200 PCT Pub. Date Jan. 20, 1994.The filter device (10) has a filter element (12) including a filter medium (20) arranged in zig-zag shaped pleats. On its two longitudinal sides extending in the pleating direction (36), the filter medium (20) is provided with stabilizing strips (34) bonded thereto for stabilizing the zig-zag-shaped pleated configuration of the filter medium (20). During use of the filter device (10), the filter element (12) is arranged within a filter element holding frame (14) which is inserted in a holding members, e.g. in the air inlet shaft (18) of an air conditioning system. Due to a certain inherent stability of shape of the filter medium (20) and the stabilizing strips (34), the filter element (12) is sufficiently firm and has a self-supporting construction. The filter element (12) is easy to handle and can be inserted into the filter element holding frame (14) in a simple manner. Except for the actual filter medium (20), the filter element (12) requires little extra material, i.e., for the stabilizing strips (34), in order to ensure stability of the device. Thus, when replacing the filter element (12), the quantity of waste material to be disposed of in addition to the filter medium (20) is extremely small.
