Eurovent 4/18: Recommendation concerning Diesel Fume: Discharging Test of Air Filters

Electrostatic effects allow filters to achieve higher efficiency with lower resistance to airflow. Exposure to some types of aerosol, such as combustion and fine particles may inhibit such charges with the result that the filter’s efficiency drops off. This diesel fume procedure is used to determine whether the filter efficiency is dependent on the electrostatic removal mechanism and to provide quantitative information about its relevance.
