A high temperature filter medium for use in a filtering operation comprising, a nonwoven fabric substrate having a physical structure and comprising a plurality of polymeric fibers, wherein at least a portion of the plurality of polymeric fibers comprise a base polymer and at least a portion of the plurality of polymeric fibers comprise a secondary polymer, and wherein the base polymer, the secondary polymer, or both bond at least a portion of the polymeric fibers together, the nonwoven fabric substrate being capable of retaining the physical structure at a filtering temperature greater than 135° C. A method for making a filter medium being capable of retaining the physical structure at a filtering temperature greater than 135° C.
