In addition, in the intake / exhaust direction switching device 2, the air 47 containing harmful substances passes through the porous material and the adsorbent 32 containing the desiccant and activated carbon, so that the moisture is adsorbed and dried, and the dried harmful substances are contained. Since the air 47 is processed in the harmful substance removal apparatus 3, a high effect is obtained for deodorization, sterilization, and purification, and at the same time, the ability of gas processing is improved. Furthermore, by switching the intake / exhaust direction switching device to the exhaust direction to the porous material and adsorbent 32 containing the desiccant and activated carbon that have adsorbed moisture, the exhaust gas in the dry state treated by the harmful substance removal device 3 is vented. By doing so, it is possible to return to the porous material and the adsorbent 32 containing the desiccant and the activated carbon which has been dried and dried again.

  Deodorizing and disinfecting with deodorizing, antibacterial, and antifungal catalysts removes odorous gases, airborne bacteria, viruses, and fungi that contain food poisoning. Since moisture does not adhere to or adsorb to odors, direct contact with malodorous gas components such as ammonia and bacteria and molds that cause food poisoning can increase the deodorizing and sterilizing effects.
