An air cleaning apparatus for a dust-free and sterile clean room necessary for an industry has a columnar body of predetermined shape having at least an air suction port and an air circulating blower, and at least a duct horizontally extending along the lower surface of a ceiling in a predetermined shape in cross section above the body. The duct has one or more clean air diffuser exits formed in a room to be cleaned for diffusing clean air into the room. This apparatus also has an air cleaning dust collector arranged between the blower and the air diffuser exits. Thus, clean air can be diffused into the room to be cleaned simply and rapidly entirely regardless of the size and the shape of the room and an already-built building. The clean room is quickly and economically constructed using the air cleaning apparatus.
