摘要： A filter element for a filter device may include a filter body having at least one filter material for filtering a fluid. The filter body may have a first side and a second side facing away from the first side. The filter body may include a plurality of body pores. The filter body may have a porosity that is lower on the first side than on the second side. A nano-fiber layer may be disposed at least partially on the first side.

摘要： A method for manufacturing a filter medium comprising at least two filter plies according to which at least a first filter ply has a plurality of thermoplastically deformable fibres, by means of which the at least two filter plies are joined to each other in some areas. The method comprises forming, by means of at least two rolls of a pressing tool, at least one additional joining region configured in a web-like manner in the at least two filter plies in which the at least two filter plies are joined to each other.
