A filter system in particular for filtering the fresh air supplied to the interior of a motor vehicle is described, including at least one particle-filtering area and at least one chemical filter area, the chemical filter area including an activated carbon filter. The particle-filtering area has a filter efficiency of T (0.3 mum)>=90%, measured according to DIN 71460/1 @ 300 m<SUP>3</SUP>/h using AC fine test dust and T (0.1 mum)>=60%, measured according to DIN 71460 @ 300 m<SUP>3</SUP>/h using NaCl as the test aerosol. The filter system is characterized by an optimized separation of diesel exhaust and in particular by a definitely improved odor reduction in the case of diesel odor.
