Abstract: A filter assembly for an enclosure, particularly for an ostomy bag, is described having an enclosure side, a first layer which is gas permeable, and an adsorbent layer comprising adsorbent particles dispersed in a fine fiber web. The enclosure side of the filter assembly includes an adhesive zone in which adhesive is present having an outer adhesive perimeter and a weld area surrounding at least a portion of the adhesive zone, where the filter assembly is heat-sealable to the enclosure at the weld area. A method of assembly is also described.

Abstract: The assemblies of the invention can comprise a fine fiber layer having dispersed within the fine fiber layer an active particulate material. Fluid that flows through the assemblies of the invention can have any material dispersed or dissolved in the fluid react with, be absorbed by, or adsorbed onto, the active particulate within the nanofiber layer. The structures of the invention can act simply as reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters that can filter particulate from a mobile fluid while simultaneously reacting, absorbing, or adsorbing materials from the mobile fluid.
