Abstract
The invention relates to a plate filter element for an air filter comprising a zigzag-shaped, folded strip material made of an activated carbon nonwoven material. The aim of the invention is to improve the dimensional stability of the activated carbon nonwoven material, especially in the area of an end fold. To this end, the invention provides that an end fold of the strip material comprises a sealing which is formed by gluing or fusing an upper side with an underside of the activated carbon nonwoven material.
