dc.description.abstractThe purpose of this thesis is to study and test the performance of the current CEVT Air-Purification System for Multiple Air Pollutants, primarily particles but also gases. The tests are designed to reveal differences between traditional air filters and a variety of other air-purification technologies such as an air ionizer, a plasma generator, and an ozone generator. Furthermore, this research is split into two sections: The first section focuses on experiments conducted in a real car cabin. The measurements in a laboratory test rig make up the second part. The results of the observations made in the two settings are compared and used to evaluate the various air cleaning technologies. As expected, the efficiency of all filters is higher at lower air flow rates (lower air velocity through the filters) than at higher air flow rates. The results show that the performance of A/F-3 improved reliability in both car and lab test-rig tests, i.e. new air filters with non-active carbon typically showed slightly higher efficiency values than the other tested filters, followed by A/F-2 new air filters with active carbon coating. Among the filters with active carbon, it was only the new one that showed any measurable reduction of organic gas.sv
