A method and apparatus for purifying appliance exhaust is accomplished by an air purification system in which an air stream is drawn into the system (2) and flows through an ozone chamber (8). The ozone chamber (8) includes an ozone generating radiation source (12) that irradiates the air stream to generate ozone which oxidizes contaminants residing in the air stream. Subsequent to traversing the ozone chamber (8), the air stream enters a germicidal chamber (16) having a germicidal radiation source (14) that irradiates the air stream and destroys bacteria and breaks down ozone residing therein. The system (2) is typically disposed in an air flow path within an appliance, such as a vacuum cleaner, to treat the air and return purified air to a surrounding environment. Further, the system (2) may be configured to remove contaminants from objects, such as food, using a porous receptacle (15) to support the object in the ozone chamber (8). Additionally, the system may be configured to remove contaminants from a user's hand.
