PURPOSE:To make it possible to take out, mount a total heat exchanger and mount and remove easily an air filter to be mounted with said total heat exchanger. CONSTITUTION:There is provided an air filter 9 which is integrally formed with an exhaust side 7 and an air suction side 8 of a total heat exchanger 1. The air filter 9 is provided with frames 10 and 11 to which filter raw materials 12 and 13 are mounted and a handle section 14 projecting in the central part. Holding pieces 17 and 18 are arranged to be partially mounted on an exhaust air passing plane and an air suction passing plane 16 of the total heat exchanger 1. This construction makes it possible to mount and remove the total heat exchanger 1 and the air filter 9 easily and simply and hence reduce cost. |
