Beschreibung
Zusammenfassung:	A filter material for an air filter may include a substrate layer on an inflow side and a fine-fibre layer on an outflow side relative to a flow direction. The filter material may include a connection region arranged between the substrate layer and the fine-fibre layer. The substrate layer, connection region and fine-fibre layer may include pores having an aggregate degressive pore size with respect to the flow direction. A combined thickness of the substrate layer, connection region and fine-fibre layer may be at least 0.35 mm. The substrate layer may include a cellulose material and have an impregnation of resin disposed along the inflow side. The resin may amount to approximately 22% by mass of the substrate layer.
