The paper gives results of tests with media filters, electrostatic filters, and electronic air cleaners. It also discusses results from system qualification tests to detect system artifacts. The collection efficiency of air cleaners as a function of particle diameter must be known to predict their ability to control specific sources. Collection efficiency from 0.01 to 3 micrometers has been measured with condensation particle counters and white-light and laser particle counters. The challenge aerosol is generated by nebulizing solutions to allow stability with respect to size distribution and concentration.
