Abstract: A microbicidal filter system having superior drop pressure and low complexity is provided, as well as a method for producing the same. The system comprises a plurality of glass beads having pores formed therebetween for the flow of air therethrough. The sintered glass beads are coated in a transition metal oxide and water. An ultraviolet light source is used to cause a photocatalytic reaction between the transition metal oxide and water. Free hydroxyl radicals with microbicidal properties are produced. Urethane foam may be inserted between the glass beads before sintering in order to cause a bimodal pore size distribution, and particulates disposed on the glass beads may be added to alter surface activity.

Abstract: A composite structure includes a substrate with pores of a first mean pore size and a coating on at least one surface of that substrate. This coating has pores of a second mean pore size where the first mean pore size is equal to or greater than said second mean pore size. When the pore size of the coating is effective to capture particulate greater than 0.2 micron, the composite may be formed into a filter effective to remove microbes from a fluid medium. One method to form the porous coating on the substrate includes: (1) forming a suspension of sinterable particles in a carrier fluid and containing the suspension in a reservoir; (2) maintaining the suspension by agitation; (3) transferring the suspension to an ultrasonic spray nozzle; (4) applying a first coating of the suspension to the substrate; and (5) sintering the sinterable particles to the substrate.
