Abstract
A filter insert which is insertable in a sealing manner into a filter housing includes an accordion fold pack whose end walls extend perpendicularly with respect to the longitudinal direction of the filter pack. Each of the end walls is surrounded in a sealing manner by a shape-stabilizing, clamp-shaped reinforcing element, each of the reinforcing elements being integrally formed in one piece with a gasket. The gasket is capable of being placed, in a sealing manner under elastic prestressing, against the adjacent housing wall of the filter housing.
