Abstract
A filter for a fluid-conducting pipe, in particular for a gas-conducting pipe of an internal combustion engine. The filter includes a self-supporting areal filter element and is fixable along a circumference 2 directly or indirectly in the pipe and, in so doing, covers a free cross section of the pipe. Here, the circumference 2 of the filter element 1 circumscribes a central filter plane 4. Furthermore, the filter element 1 or at least one layer thereof is comprised of a plastically deformable material and is provided with at least one undulation 5 or bead 13, which does not intersect the circumference 2, in such a way that the filter element 1 intersects the filter plane 4, or a plane 4a parallel thereto, at least four times within the circumference 2.
