Abstract (en)
[origin: WO2013068073A1] The invention relates to a filter surface element for forming a prefilter layer (22) of a multilayer filter medium (12), comprising an outer surface associated with an inflow side (A) of the filter medium (12). The filter surface element is characterized in that at least one depression (32) is introduced into the filter surface element starting from the outer surface such that each depression (32) at least partly penetrates into the filter surface element or completely passes through same.
