A filter drier (10) for an air conditioning or refrigeration system, has a body (12) with an interior area (20). The unit has an inlet opening (24) and an outlet opening (30). The outlet opening is in connection with an outlet tube (34) that extends substantially the length of the interior of the body. Donut shaped housings (54, 56) holding particles of desiccant material, are sandwiched between a first baffle (36) and a second baffle (72). The housings have an upper filter pad (58) of rigid, coarse fiber material, and a filter bag (62) of fine, flexible fiber material. In each housing, the filter bag is attached to the filter pad about its outer periphery at a seam (66), and at a seam (68) which is adjacent an opening (60) in the pad, through which the outlet tube extends. The filter bags of the donut shaped housings are deformed upon assembly to insure contact with the inner wall of the housing and the exterior surface of the outlet tube. The filter drier has increased contaminant absorbing capability and modular construction for ease of assembly.
