Abstract
Abstract A system for eliminating odors by using an odor scavenger member having a textile substrate or the like impregnated with odor scavenging materials such as N-trisubstituted ammonium-2-hydroxy-3-halopropryl compounds or salts of epoxy propyl ammonium compounds such as glycidyltrimethylammonium chloride. Such members, and the methods of making and using same are included.
