An increasing number of people realize that the particulate and gaseous pollutants entering a car through the ventilation system may cause comfort and health conserns. To address these concerns, manufacturers equip their new models with cabin air filters. These filters help reduce pollutants and odors that can reach driver and passengers. In Europe, cabine air filters are routinely tested according to DIN standard 71 460 (draft status). Analogous to Air Filter Test Code J1669 (draft), Part 1 of the DIN standard prescribes ISO test dust (commonly known as Arizona road dust) for loading the filters. This paper contains data for several commercially available filters, measured according to DIN procedure. A comparison with field test data from three different test regions will be presented at the conference. It is shown, that the standard test procedure does not do a very good job in predicting real-life loading behavior. This is especially true for regions with a high degree of pollution. Later this year, the European Filtration Laboratory of 3M expects to present new data, obtained with a multiple component loading aerosol.
