ABSTRACT:
An air filtration or fluid treatment system includes 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) to the fiber surface and each retaining within the internal cavity a large number of relatively small solid particles (18) which interact with the air or other fluid stream to be treated. The solid adsorbent particles (18), such as activated carbon, are permanently entrapped within the longitudinal cavities (22) of the fibers (20) without the use of an adhesive or without being embedded onto or within the polymer fiber.
