Abstract:
1. An air cleaner for catalytic oxidation of contaminant gasses comprising: a housing defining an enclosure and having an air entrance and an air exit; a pre-filter positioned to filter air entering said enclosure through said air entrance; a crystalline microporous/nanoporous filter within said enclosure, the crystalline microporous/nanoporous filter comprising filter material held in a filter enclosure that is an electrical insulator; an oxidant generating device for promoting catalytic oxidation of gaseous contaminants on said crystalline microporous/nanoporous filter wherein the oxidant generating device comprises an ion generator positioned in said stream of air upstream from said filter and said ion generator comprises an AC 30-60 kV ion generator which provides both positively and negatively charged ions to assist in the decomposition of said gaseous contaminants on said filter; and a blower arranged to generate a flow of air through said pre-filter and said crystalline microporous/nanoporous filter, wherein, the oxidant generating device is placed before the crystalline microporous/nanoporous filter along the direction of said flow of air, so that after said flow of air passes through the oxidant generating device, contaminant gasses in said flow of air and the oxidants from said oxidant generating device are directly and simultaneously adsorbed into the pores of said crystalline microporous/nanoporous filter, initiating break down of the contaminant gases with the pores of the filter by catalytic oxidation reaction with the oxidants generated from said oxidant generating device selectively at ambient temperature, in such a way contaminant gasses is simultaneously adsorbed and decomposed, and the microporous/nanoporous filter is continuously regenerated.
