Abstract
An improved catalytic filter material for use in removing target species found in a fluid stream is provided. The filter material includes water wettable, high temperature staple fibers in the form of porous substrates that are attached to a high temperature fluoropolymer woven scrim. The porous substrates have catalyst particles adhered (e.g., tethered) to the surfaces thereof by a polymer adhesive. Optionally, at least one microporous layer is positioned adjacent to or within the filter material.
