An air purification apparatus 3 comprises an inlet 32 for airflow, an outlet 34 for purified airflow, a channel 36 extending from the inlet to the outlet, and an ultraviolet (UV) light source 38 to emit UV light into the channel to purify the airflow. The apparatus comprises a reflector 42 to reflect the UV light within the channel and an absorber arrangement 44 to absorb the UV light to inhibit leakage of the UV light through one or both of the inlet and the outlet. The apparatus can be sized to be received and attached as removable module to a zonal HVAC duct 24 of a vehicle via fixing points (58). The UV light source may be UVC LED’s emitting a wavelength between 200nm and 280nm. The apparatus may comprise a temperature regulator (20, 45 figs 2A & 5) to control a rate of heat dissipation from the UV light, and may comprise an electronic thermostat (20) and a passive heat exchanger (45). The heat exchanger may be a heatsink having fins (46) protruding into the channel. The absorber may be a coating exhibiting photocatalytic activity upon irradiation by the UV light upstream and downstream of the reflector.
