The invention relates to an air purification system intended to be fitted to a building comprising an air purifier equipped with a fan coupled to at least one filter in order to produce filtered air thereby reducing the microparticles or VOC or other-gas content of this air. The system comprises a plurality of pairs made up of an inlet sleeve and of an outlet sleeve through which there passes a stream of air propelled by said fan. The system also comprises a plurality of pairs made up of an air inlet opening connected by a duct to an outlet sleeve so as to inject the filtered air stream into a room of said building and of an outlet opening connected by another duct to an inlet sleeve for extracting air from this room to be filtered. The purification system further comprises pollution sensors that measure the level of pollution in each incoming air stream and a controller board that triggers the opening of an inlet flap controlling the inlet of air to the inlet sleeve and of an outlet flap controlling the outlet of air from the outlet sleeve of the same pair, the opening of said flaps being proportional to the measured level of pollution. In this way, it is possible very accurately to control the filtering of the air in each room of the building and notably not to filter air in rooms that are unoccupied. |
