Abstract: The invention relates to the field of air purification, sterilization, disinfection, sanitization, removal of particulate matter and harmful gases. A UV light source(102), which is preferably positioned parallel to the flow of air ensuring continuous disinfection of the airstream due to increased residence time, and a filter (106) that is preferably positioned surrounding/around the UV source. In an embodiment, the invention is disclosing a self-cleaning ability that is achieved by using electrostatic fields. In another embodiment, a small, compact self-cleaning purifier/device can be used to sanitize small, enclosed spaces like cars, cabins, etc.
