Aerosol Filtration Efficiency of In-Duct Air Cleaners

摘要

The paper discusses the evaluation of the fractional efficiency of several commonventilation air cleaners. The air cleaners included fiberglass furnace filters, paper-media filters, and electrostatically charged fiber cleaners. Results showed that filtration efficiency is highly particle size dependent over a 0.01-10 micrometer size range. Filtration efficiency was also seen to be dependent upon flow rate and the dust load condition of the air cleaner.
