PROBLEM TO BE SOLVED: To provide a filter mounting case which is capable of easily putting a filter unit in and out and is capable of assuring a high filtration function by sufficiently pressing the filter unit to a supporting frame. SOLUTION: A supporting shaft 11 spanned in parallel with the insertion direction of the filter unit 4 on the front surface side of the filter unit 4 inserted from an insertion port 5 mounted with an opening/closing door 6 is turned by a lever 10, by which the filter unit 4 is pressed and mounted to a supporting frame 13 on the rear surface side by freely turnable ring members 29 of filter pressing parts 12 disposed near both ends of the supporting shaft 11. The filter pressing parts 12 are retreated so as not to restrain the filter unit 4 when putting the filter unit 4 in and out.
