/Cyclonic Ultraviolet Air Purification Chamber
Abstract

Disclosed are methods and devices for air purification using photocatalytic oxidation that include an air purification device that includes an inlet; a first chamber including at least one first emitter and at least one filter media, with the at least one first emitter configured to irradiate at least a surface of the at least one filter media; a second chamber configured to receive air from the first chamber, with the second chamber including at least one second emitter; at least one plate provided in the second chamber; and an exhaust formed on the second side of the second chamber, with the at least one second emitter being configured to irradiate at least a portion of the at least one plate, and with the second chamber being configured to induce cyclonic air flow therein.
