PURPOSE:To obtain an air cleaning system capable of collecting contaminants such as cigarette smoke, etc., which are generated in a room and of cleaning air in the room without scattering contaminants throughout the room. CONSTITUTION:An air cleaning system has a groove 2 on the room side of a ceiling 1, and an air outlet 3 and an air suction port 4 are respectively provided at both ends of the groove 2 so that an air current from the air outlet 3 toward the air suction port 4 is produced in the groove 2. The air suction port 4 communicates with an air cleaner 7 through a duct 8, and the air cleaner 7 communicates with the air outlet 3 through the duct 8. |
