Patent ID: 7144551

Claim:
A process for reducing and killing bioburden, including molds, bacteria and their spores, yeast, and viruses comprising the steps of: a) providing a vessel in an air conduit of an existing ventilation system inside a structure selected from the group consisting of a home or office building, the vessel containing an aqueous solution at a first pH level which comprises a compound from which a gaseous hypochlorous acid may be evolved upon adjustment of said aqueous solution to a second pH level; b) adjusting the pH of said aqueous solution from said first pH level to said second pH level so as to cause vapors comprising an hypochlorous acid to be evolved from said solution, and thus forming an actively-evolving solution; c) causing an air current to exist in the ambient surroundings of said vessel from which said vapors are evolved so as to provide an air stream which contains a gaseous hypochlorous acid; and d) directing the flow of said air current to a location at which said bioburden is growing for an effective amount of time to kill said bioburden.
