A filter element and related method for separating particles from a particle laden unfiltered gas flow and a method for manufacturing such a filter element, wherein the filter element includes a first filter wall having a plurality of first through-flow openings for entry of contaminated unfiltered gas; a second filter wall disposed downstream of the first filter wall in the flow direction, and having a plurality of second through-flow openings for exit of clean gas; and an intermediate flow space disposed between the first and second filter walls, wherein the second through-flow openings are arranged in a displaced relationship with the first through-flow openings in the flow direction; the second filter wall has at least one impingement wall region arranged so that particles passing through the first through-flow openings at least partially impinge thereon; and at least one of the first and second filter walls has folds which extend alternately inward and outward relative to the intermediate flow space and has increased deformability in relation to the rest of the wall.
