ABSTRACT:
Elastomeric nonwoven fibrous fluid filter media for removal of particulate contaminants from the fluid are provided. The filter media comprises thermoplastic elastomeric melt-blown small diameter fibers, the small diameter fibers being randomly arrayed, the filter media having substantially uniform stretch properties in all directions and whose filtration properties are independent of filter media elongations sufficient to increase the filter media surface area at least about 10 percent. The filter media is particularly useful as a prefilter on respirators.
