A filter element for a pressure filter where a substantially horizontal wall (3) divides the interior of a pressure vessel into a lower inlet compartment (5) and an upper outlet compartment (6). A filter element (20) having a filter medium (40) is suspended from the wall (3) such that the filtering takes place from the inlet compartment (5) through the filter element (20) up to the outlet compartment (6). A corrugated sheet (22) is provided which defines a plurality of substantially vertically extending channels (45) and (42). Each first channel (45) is open the inlet compartment (5) with the filter medium (40) covering the first channels (45) with the upper end of the first channels (45) being closed and the lower end of the first channels (45) being open at (43). The second channels (42) being formed on an inner side of the corrugated sheet (22) with an open bottom end and an upper end communicating with the outlet compartment (6).
