The paper discusses a test method for measuring the fractional aerosol filtration efficiency of air cleaners. The method provides a reliable and accurate way to measure air cleaner fractional efficiencies over the particle diameter size range of 0.01 to 10 micrometers. The need for a fractional efficiency test comes from several sources: (1) the growing concern with indoor air quality (IAQ); (2) that filtration efficiency is often highly particle-size dependent for particles < 10 micrometers in diameter; (3) limitations of the current American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) efficiency test which, by design, cannot differentiate between particle sizes; and (4) that respirable particles are generally classified as those < 10 micrometers in diameter.
