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.

[ We claim:] [1.] Apparatus for removing molecules from a fluid stream comprising:a plurality of elongated fibers each having multiple lobes with a longitudinally extending internal cavity including an opening from the internal cavity to the outer fiber surface formed between adjacent lobes;a fine powder, made from particles which can adsorb the molecules, disposed within the internal cavities of said plurality of elongated fibers;a flow path for the fluid stream, containing the molecules to be removed, directed over a portion of said plurality of elongated fibers whereby the molecules to be removed are adsorbed by said fine powder; and,said fine powder particles being of such a size, shape and makeup that they are securely retained mechanically within the internal cavities.
