An air purifier includes an interior volume divided into upper and lower chambers, with a motorized fan assembly being positioned within the upper chamber. An ultraviolet (UV) light source is positioned within the lower chamber. A lower fan shroud includes concentric annular ribs that extend axially into the lower chamber and terminate in respective flared distal ends. The flared distal ends deflect light from the UV light source to reduce leakage of the light into the upper chamber. A diffuser can surrounds the UV light source, is affixed to the fan shroud, and has angled louvers deflecting the light to further reduce leakage thereof. Embodiments include a cylindrical media basket surrounding the diffuser can and having a media material disposed therein or thereon. The louvers are oriented to direct the light from the UV light source toward the media material.
