Abstract: An air purifier for use in a vehicle having louvered air vents includes a housing having rear and front air flow openings that are aligned with and in air flow communication with each other. A louver clip is attached to the housing adjacent the rear air flow opening. The louver clip is configured to engage a louver on an air vent in the vehicle to hold the housing in place in front of the air vent. The air purifier includes an annular ultraviolet light bulb having a central air flow opening aligned with the front and rear air flow openings in the housing. An annular ultraviolet reflector at least partially encircles the annular ultraviolet light bulb. The air purifier includes a power source for providing electrical power to the ultraviolet light bulb, and a power switch for turning power on or off to the ultraviolet light bulb.
