Abstract
The invention relates to a filter for filtering a liquid or a gas, with a pocket-shaped filter element which has a sleeve-shaped circumferential region, a closed head region and an open foot region, and with a frame element which has an annular base, in which the foot region of the filter element is accommodated, and at least one supporting strut which extends away from the base along the circumferential region of the filter element. An advantageous design of the filter is achieved by forming the head region of the filter element with a saddle shape, wherein two lateral tips are provided between which a channel-shaped recess is formed.
