An ultra-efficient multilobal cross-sectioned fiber filter for chemical contaminant filtering applications is described. An absorptive chemically reactive reagent, preferably an acid or base and in liquid or an adsorptive chemically reactive reagent (an acid or base) in solid form, is disposed within longitudinal slots in each length of fiber. The reagent may be used alone or in conjunction with solid adsorptive particles which may also be utilized with the reagents in the longitudinal slots within the fibers. Reagents within the fibers remain exposed to a base-contaminated airstream passing through the filter. Base contaminants in the airstream, chemicals such as ammonium and amines (as well as particles), react with the acid reagent within the longitudinal slots of the fibers. As the contaminant and reagent react, the ammonium or amine becomes irreversibly absorbed (or adsorbed if reagent is a solid acid) to the liquid acid reagent and multilobal fiber.

We claim: 1. A fiber mat comprising: a plurality of elongated fibers, each fiber comprising an internal cavity; a plurality of powdered particulate matter; and a chemically-reactive reagent disposed within the internal cavities of the fibers, wherein the reagent comprises at least one acid, at least one deliquescent agent or a combination thereof with at least one acid, with at least one base, at least one coordinating agent comprising at least one transition metal, at least one deliquescent agent, wherein the at least one deliquescing agent comprises lithium, a potassium halide, fructose, propylene or ethylene glycol. 2. The mat of claim 1, wherein the at least one acid comprises a liquid acid. 3. The mat of claim 1, wherein the at least one acid comprises a powdered acid. 4. The mat of claim 1, wherein the at least one base comprises a powdered base. 5. The mat of claim 4, wherein the powdered base comprises sodium bicarbonate, sodium carbonate, sodium hydroxide, trisodium phosphate, potassium carbonate, potassium hydroxide or sodium tetraborate. 6. The mat of claim 1, wherein the at least one transition metal comprises copper. 7. The mat of claim 6, wherein the plurality of fibers comprise at least one thermoplastic polymer. 8. The mat of claim 1, wherein the powdered particulate matter comprises carbon powder. 9. The mat of claim 1, wherein the powdered particulate matter comprises zeolite, aluminum oxide or silica. 10. The mat of claim 1, wherein at least some of the plurality of fibers are trilobal. 11. The mat of claim 1, wherein at least some of the plurality of fibers are quadrilobal. 12. The mat of claim 1, wherein at least sonic of the plurality of fibers contains a plurality of T shaped lobes. 13. The mat of claim 1, wherein the mat is pleated. 14. The mat of claim 1, further comprising a frame coupled to the mat. 15. A housing comprising the mat of claim 14. 16. A gas filter comprising the mat of claim 1. 17. A filtering chamber comprising the mat of claim 1.
