ABSTRACT:
A nonwoven filter media or mat (10) formed from a plurality of elongated generally hollow fibers (20) each having an internal cavity (22) which has an opening (24), smaller than the cavity width, to the fiber (20) surface and each retaining within the internal cavity (22) a large number of relatively small solid particles (18). The small solid particles (18), which can be an adsorbent such as activated carbon, are permanently entrapped within the longitudinal cavities (22) of the fibers (20) without the use of an adhesive.
