An air purification and disinfection apparatus incorporates an air inlet filter ( 1 ) spanning the intake of the apparatus, an ultraviolet light source ( 2 ) for treating the air within a chamber ( 14 ) of the apparatus, and an equalising screen ( 3 ) spanning the outlet of the apparatus. The chamber ( 14 ) is lined with a reflective sheet ( 11 ) or coating such that the ultraviolet light is reflected around the chamber ( 14 ). The air inlet filter ( 1 ) removes larger airborne particles from the airflow prior to entering the chamber ( 14 ). The light source ( 2 ) may be located in the chamber ( 14 ) or in a housing ( 16 ) which communicates with the chamber ( 14 ). With the reflective surface of the chamber ( 14 ), the intensity of the light source ( 2 ) can be maintained when dirt begins to build up on the light source ( 2 ), thereby extending the length of time that passes between each cleaning of the light source ( 2 ).
