<p>PROBLEM TO BE SOLVED: To provide an air filter capable of being easily exchanged without damaging a filtering material. SOLUTION: An L-shaped hook-like angle member 5 is vertically mounted to inner sides of right and left lateral side plates 2 of a case to which an upper plate is attached/detached. Pleats at right and left ends of the filtering material 4 inserted from above while directing the pleats to a vertical direction are smoothly guided to an insertion direction. The filtering material 4 can be easily exchanged without damaging it by sealing both right and left ends of the filtering material 4 by an engagement of these pleats at the respective ends and the hook-like angle member 5.</p> |
