PROBLEM TO BE SOLVED: To provide a ventilation fan filter capable of being easily divided into a metal-made filter frame and a nonwoven fabric-made filter material in being disposal-treated since, when the ventilation fan filter is immersed into water in the case of being disposed after use, adhesion between the metal and the nonwoven fabric by a film-forming polymer is decreased, and the metal-made filter frame 1 can be easily peeled off from the nonwoven fabric-made filter material 2 by one's fingers. SOLUTION: The ventilation fan filter is provided by bonding the metal-made filter frame 1 to the nonwoven fabric-made filter material 2. The nonwoven fabric-made material 2 covers and opening 7 provided to the metal-made filter frame 1 to be bonded by an opening edge part 3 and/or a crosspiece part 4. This bonding is carried out by using aqueous emulsion based adhesives. The glass transition point of the above film-forming polymer is preferably +10 deg.C to +60 deg.C. |
