Abstract Recently, great efforts are being made to develop filter media which fulfill the requirements on a good cabin air quality. Based on the nonwoven technology new media concepts were developed. With the new generation of fine dust cabin air filters it is possible to achieve separation efficiencies of more than 80 % for a test aerosol (NaCl aerosol) at the most penetrating particle size (MPPS) by maintaining other important factors like pressure loss and filter life time. It can be shown that this new filter media concept is able to better maintain the particle separation efficiency over the filter life time under realistic conditions. Usually cabin air filter performance is measured according DIN 71460-1 under laboratory conditions. In order to improve the properties of the filter media towards their real-life behavior experiments were conducted with a test car. Here the corresponding particle concentrations in the cabin were measured under varying driving situations and environmental conditions.
