1. A filter element comprising:
a filter medium body of a filter medium, the filter medium body comprising:
an inflow face of the filter medium body;
an oppositely positioned outflow face of the filter medium body;
wherein an axial direction, as used herein, is a direction from the inflow face to the outflow face of the filter medium body;
wherein the filter medium body has at least one lateral side which extends from the inflow face to the outflow face; and
wherein the filter medium is folded into a plurality of folds forming pleats extending from the inflow face to the outflow face;
wherein a first rim edge is formed by the filter medium body where the inflow side meets the at least one lateral side;
wherein a second rim edge is formed by the filter medium body where the outflow side meets the at least one lateral side;
a first sealing or supporting element cast, foamed or injection molded onto the first rim edge the filter medium body at the inflow face;
a second sealing or supporting element cast, foamed or injection molded onto the second rim edge the filter medium body at the outflow face;
a plurality of force-transmitting adhesive beads applied and adhesively fixed directly onto the filter medium body, the plurality of force-transmitting adhesive beads extending continuously between and connecting the first sealing or supporting element to the second sealing or supporting element,
wherein the sealing or supporting elements are contacting against respective axial ends of the plurality of force-transmitting adhesive beads, such that forces are passed through the plurality of force-transmitting adhesive beads from the first sealing or supporting element to second sealing or supporting element, thereby bypassing axial forces around filter medium of the filter medium body; and
wherein at least one of the plurality of force-transmitting adhesive beads is positioned a predetermined distance from the at least one lateral side of the filter medium body creating a plurality of chambers.
