Filter element

A filter element comprising:

• a zigzag-shaped fold pack comprised of fold sections of filter media, said fold sections joined along adjacent edges by fold edges,
• wherein each fold edge loins together two adjacent filter media fold sections;
• at least one terminal element having:
• a second leg having opposing first and second edges, said second leg secured to a fold end section of said filter media fold pack,
• a first leg arranged parallel to the fold edges of the fold pack, said first leg joined to said first edge of said second leg by a first fold, said first leg not joined to any other legs,
• and
• a third leg joined to said second edge of said second leg by a second fold,
• wherein the first leg is arranged substantially perpendicularly to a flow direction of a medium flowing through the filter element,
• wherein said first and third legs are not arranged on opposing faces of one of said fold sections,
• wherein the first, second and third legs are substantially flat without folds,
• wherein said first, second and third legs form a continuous folded sheet,
• wherein at least one lateral web is attached unitarily to ends of several of the fold sections of the fold pack, the ends result from cutting the fold pack in a direction traverse to the folds,
• wherein the third leg projects laterally away from the filter element to form a peripheral seal.
