A fiber filter, method of preparing the fiber filter, and method of treating a fluid stream with the fiber filter are disclosed. The fiber filter comprises an inert fiber matrix, water, and a substrate bound to the fiber matrix that is capable of oxidizing or neutralizing a contaminant. More specifically, the substrate bound to the fiber matrix is sodium bicarbonate, impregnated activated alumina, impregnated zeolite, or a mixture thereof. The impregnate is a permanganate salt, sodium bicarbonate, or a mixture thereof. Improved efficiency of removal of undesirable compounds such as hydrogen sulfide and sulfur dioxide from fluid streams is achieved.

[ What is claimed is:] [1.]1. A method of making a fiber filter, comprising:(a) impregnating a substrate coated fiber matrix with an aqueous impregnate solution; and(b) drying the resultant fiber filter until the concentration of water is between approximately 5 and 30%, and the concentration of the fiber matrix is between approximately 5 and 75%, by weight of the fiber filter;wherein the impregnate is a mixture of a permanganate salt and sodium bicarbonate, wherein the substrate is selected from the group consisting of activated alumina and zeolite, and wherein the fiber matrix is inert to the impregnate.
