Abstract

The invention relates to a filter arrangement comprising a pleated nonwoven layer for use as a motor vehicle interior filter. The nonwoven layer is in the form of a single-layer, self-supporting micro-spunbonded fabric, the grammage thereof being between 70 g/m2 and 200 g/m2, preferably between 110 g/m2 and 150 g/m2, the thickness thereof being between 0.7 and 1.5 mm, and the fibre thickness being between 2 and 20 µm with an average fibre thickness of 3 to 5 µm.
