<p><P>PROBLEM TO BE SOLVED: To provide a filter pack capable of improving sealability between a filter pack and a filter frame and preventing lowering of sealability from the upstream side to the downstream side caused by a cushioning material being rubbed and peeling off between a flat portion of the filter frame and the cushioning material during exchange of the filter pack, and to provide an air filter having the same. <P>SOLUTION: By folding (2a-2d) the sheet-like cushioning material 2 toward the ventilation surface side on the downstream side of a filter medium 1 formed into a rectangular parallelepiped shape from respective surfaces 1a-1d sandwiching a ventilation passage of the filter medium 1, a filter pack 10 with sealability assured on the downstream side is obtained even when sliding with an inner-periphery surface of the filter frame occurs during the exchange. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
