Patent ID: 8585979

Claim:
An apparatus for ionizing air, the apparatus comprising: a chamber including: a top portion, a bottom portion, a first side including a first target comprising: a plurality of passages between an interior area of the chamber and an exterior area of the chamber, and a photo-catalytic coating on the plurality of passages; a second side opposite the first side and including a second target comprising: a plurality of passages between the interior area of the chamber and the exterior area of the chamber, and the photo-catalytic coating on the plurality of passages; a first reflector arranged on the top portion of the chamber and configured to: reflect UV energy emitted along a dimension towards the first target from a UV emitter located within the chamber directly to the photo-catalytic coating of the first target, wherein the first reflector is a specular UV reflector, and reflect UV energy emitted along a dimension towards the second target from the UV emitter directly to the photo-catalytic coating of the second target; a second reflector arranged on the bottom portion of the chamber and configured to: reflect UV energy emitted along a dimension towards the first target from the UV emitter located within the chamber directly to the photo-catalytic coating of the first target, wherein the second reflector is a specular UV reflector, and reflect UV energy emitted along a dimension towards the second target from the UV emitter directly to the photo-catalytic coating of the second target; and wherein the photo-catalytic coating is arranged to: receive UV energy directly from the UV emitter, receive UV energy reflected from the first reflector, and receive UV energy reflected from the second reflector.
