9. An air purifier for use in a vehicle having louvered air vents, the air purifier comprising:
a housing comprising:
a front housing portion comprising:
a front air flow opening;
a plurality of front radial vent spokes that span the front air flow opening in a radial pattern, such that the front air flow opening is divided by the front radial vent spokes into a plurality of front air flow channels; and
a rear housing portion comprising:
a rear air flow opening that is aligned with and in air flow communication with the front air flow opening;
a plurality of rear radial vent spokes that span the rear air flow opening in a radial pattern, such that the rear air flow opening is divided by the rear radial vent spokes into a plurality of rear air flow channels,
a rear hub centrally disposed within the rear air flow opening, wherein proximal ends of the plurality of rear radial vent spokes terminate in the rear hub; and
a central aperture centrally disposed through the rear hub;
a louver clip attached to the rear housing portion adjacent the rear air flow opening, the louver clip configured to engage a louver on a louvered air vent in the vehicle and to hold the housing in place in front of the louvered air vent, the louver clip comprising:
a flange;
a plurality of prongs extending forward of the flange, wherein the prongs are operable to flex inward as tips of the prongs are pressed into the central aperture of the rear hub, and wherein the prongs are operable to snap outward to secure the louver clip against the rear hub as the tips of the prongs pass through the central aperture; and
a pair of opposing jaws extending rearward of the flange, wherein the opposing jaws are operable to flex outward away from each other to engage and clamp onto the louver in one of the air vents in the vehicle;
an annular ultraviolet light bulb disposed within the housing, the ultraviolet light bulb having a central air flow opening aligned with and in air flow communication with the front air flow opening and the rear air flow opening in the housing;
at least one annular ultraviolet reflector disposed within the housing and at least partially encircling the annular ultraviolet light bulb, wherein the least one annular ultraviolet reflector comprises front and rear reflector portions, and wherein the annular ultraviolet light bulb is sandwiched between the front and rear reflector portions;
a power source disposed at least partially in the housing, the power source for providing electrical power to the ultraviolet light bulb; and
a power switch disposed at least partially in the housing, the power switch for turning power on or off to the ultraviolet light bulb.
