Abstract

The invention relates to filter media particularly for purification of water. Disclosed is a filter medium having incorporated therein a compound of Silver and Copper hydroxide. Copper hydroxide and a silver compound when present in the filter medium provide significantly greater log reduction of virus and bacteria in water rendering the water purer.
