Abstract
An apparatus for irradiating air flow in a vehicle includes a filter unit configured to couple to a recirculating-air conduit connected to a manifold of an air circulation system, the filter unit having an inlet end, and a filter disposed in the inlet end of the filter unit, including an outer wall of filter media having a shape that defines an interior volume of the filter. The apparatus further includes an ultraviolet light disposed on an end plate, configured to be mounted with the ultraviolet light positioned in the interior volume of the filter and the end plate against an open end of the filter. The ultraviolet light is configured to emit ultraviolet radiation substantially at between 222 nm and 265 nm for irradiating air flow through the filter into the air circulation system.
