Abstract:
1. A filtration system comprising of: an activated carbon filter medium, in combination with a high wet strength nanofiber composite having a mean pore diameter of less than about 1 μm, and a microbiological interception enhancing agent that comprises a cationic metal complex comprising a cationic material adsorbed on at least a portion of said filtration system, said cationic material having an associated counter ion therewith capable of imparting a positive charge on at least a portion of said filtration system, and wherein a biologically active metal is caused to precipitate with at least a portion of the counter ion associated with the cationic material, wherein the nanofiber composite comprises of majority fibers; and minority fibers admixed with the majority fibers wherein the minority fibers have a softening point lower than the majority fibers such that when the admixture of majority fibers and minority fibers are subjected to pressure and a temperature above the softening point of the minority fibers, the majority fibers are coalesced into said high wet strength composite.
