ABSTRACT:
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).
