Abstract
A study was conducted to determine the filtering efficiencies of 31 high-efficiency particulate air (HEPA) filtration units in use at asbestos-abatement projects. Particle-removal efficiencies for these units ranged from 90.53 to > 99.99 percent. Nineteen (61%) of the units tested in the study demonstrated efficiencies below the ANSI N509-1980 minimum efficiency of 99.95 percent. Sixteen (52%) of the HEPA filtration units produced airborne asbestos concentrations in the exhaust stream significantly greater than outdoor concentrations. The study demonstrates that substandard performance of HEPA filtration units can result in the release of asbestos fibers into the outdoor air or into adjacent building areas.
