Abstract

The present invention is directed to novel filter bag assemblies comprising a support structure, such as a support cage of metal, plastic, or the like, and a filter media of expanded PTFE membrane(s) without a backing material or layer. In a preferred embodiment, the filter bag assembly further comprises a support cover, or cage cover, which fits over the exterior surface of the support, or cage, to prevent contact of the filter media with the cage.
