摘要： 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.

摘要： A pleatable and cleanable filter media (22) that has a HEPA filtration rating. The filter media (22) includes a porous primary filtration layer (22). The primary filtration layer tending to be less than HEPA rated upon being damaged. A first substrate layer (64) attached to said primary filtration layer (62) for maintaining the shape of the filter media (22). The first substrate layer (64) includes a non-woven filtration media and being less than HEPA rated. A second substrate layer (82) attached to the first substrate layer (64) functioning as a secondary filter in the event of damage to the primary filtration layer (62). The second substrate layer (82) includes a non-woven filtration media and being less than HEPA rated.
