Abstract

The system (10) comprises a casing (11) defining an inlet for the air to be purified and an outlet for the purified air. The system further includes an electrostatic filter (12) and a photocatalytic filter (14) located in the casing (11). The photocatalytic filter (14) further comprises an electromagnetic source assembly (16) configured to generate an electromagnetic radiation, and a filter module (18) composed of a photocatalytic material that can be activated by the electromagnetic radiation; the system includes a fan (20) located in the casing (11) between the electrostatic filter (12) and the photocatalytic filter (14) and comprising an impeller (22) configured to convey an air flow through the filters (12, 14). A control unit (24) is configured to control the electromagnetic source assembly (16) and the fan (20).
