PROBLEM TO BE SOLVED: To improve operability in the case of exchanging an ozone filter element and to prevent the ozone filter element from being damaged at the exchanging time by using the whole of the ozone filter element itself as a renewal part without special treatment. SOLUTION: A filter housing part 22 is provided in a ventilation path connecting the exhaust port of an exhaust fan 5 with the exhaust part 1a of an outside housing 1, and an loading/unloading port opening in an loading/ unloading direction is formed at the upper end of the housing part 22. In a state where the ozone filter element 3 is loaded in the housing part 22, a member for loading/unloading 23 is interposed between the inner surface of the housing part 22 and the outer surface of the ozone filter element 3 and bent in a recessed state, and its grasping part 23a is extended to the outside from the housing part 22 and its fixed part 23b is fixed in the vicinity of the entrance part of the housing part 22. A user pulls the grasping part 23a to extend from the housing part 22 upward or outward with respect to the filter element 3, whereby the filter element 3 is unloaded from the housing part 22. |
