Abstract

The invention relates to a filter material in particular for an air filter wherein the filter material (1) has a diminishing pore size in the flow direction (5) and wherein the filter material (1) has a substrate layer (2) on the inflow side and a fine fiber layer (4) in particular a melt blown layer on the outflow side. It is essential to the invention that a connection region (3) is arranged between the substrate layer (2) and the fine fiber layer (4) that the filter material (1) has a thickness (d) of d > 0.35 mm and that an impregnation (6) is applied at least to the inflow side of the substrate layer (2). Thus an especially high performance filter material (1) that combines the advantages of the individual layers (2 4) can be created.
