PROBLEM TO BE SOLVED: To provide a case for a cleaning filter and a cleaning filter capable of simplifying a manufacturing process of the cleaning filter. SOLUTION: A cleaning filter 1 is manufactured by charging and filling pellets P from a pellet charging port 17 into a case 2 for the cleaning filter comprising a frame member 10 and nonwoven fabrics 16, 16 bonded on both sides thereof, and connecting a lid member 18 to this pellet charging port 17. As the case 2 for the cleaning filter manufactured by previously bonding the nonwoven fabric 16 and 16 to both sides of the frame member 10 at a time can be used, this manufacturing process of the cleaning filter 1 can be simplified as compared with a process bonding nonwoven fabric by each side. Moreover, as lateral partition walls 14, 14, 15, 15 are set alternately, the pallets P are not inclined to the lower part even when the cleaning filter 1 is vertically positioned, and can be filled into the case 2 for the cleaning filter without any gap in the vertical manner. |
