A method and apparatus for producing purified or ozone enriched air to remove contaminants from objects is accomplished by a system in which air is drawn in as a stream into the system and flows through ozone generating and germicidal chambers. An ozone generating ultraviolet (UV) radiation source disposed within the ozone chamber emits UV radiation having a wavelength of approximately 185 nanometers to irradiate the air and generate ozone. The ozone chamber is typically configured to include winding or other types of air flow paths to mix the ozone with the air. The ozonated air enters a germicidal chamber including a germicidal UV radiation source (e.g., emitting radiation having a wavelength of approximately 254 nanometers) that irradiates the ozonated air to destroy contaminants and to catalyse the ozone for enhanced removal of odor causing elements from the air stream. An internal fan draws air through the system. The system may include a baffling arrangement to control air through-flow velocity, or be configured to utilize a replaceable cartridge with or without a stationary base. The system may additionally be configured: to remove contaminants from various objects (e.g., a user's hands, infant peripherals, liquids, etc.); for use within a toothbrush holder to remove contaminants from toothbrushes; to be transportable for removal of contaminants from portions of the human anatomy or objects coming in contact with the anatomy; or for use within a self-cleaning toilet seat to remove contaminants from the seat. |
