Patent ID: 7407633

Claim:
A pathogen neutralization system, comprising a flow-through reaction chamber having a chamber air inlet located at a first end of the reaction chamber to admit air that is to be disinfected, and a chamber air outlet located at a second end of the reaction chamber to release disinfected air, and defining therebetween a passageway for the passage of air that is to be disinfected through the reaction chamber, the passageway containing no filters and otherwise being substantially free of any obstructions so as not to impede the passage of air through the reaction chamber thereby permitting the neutralization of airborne pathogens in large volumes of ventilated air in real time, wherein the reaction chamber further comprises a. an ozone generator; b. a water supply line; c. an ultraviolet light source separate from the ozone generator; and d. a porous matrix for providing increased surface area on which the neutralization of pathogens can occur, wherein the porous matrix consists of metal foam.
