The study was conducted to assess the in-place performance of high-efficiency particulate air (HEPA) filtration systems at asbestos-abatement sites in New Jersey to determine each system's particle-removal efficiency. An air-generated dioctyl phtalate aerosol was used to challenge the filtration system, including possible filter and housing bypass leaks, or damaged filter medium. Sixteen percent of the HEPA-filtration systems tested showed particle-removal efficiencies lower than the American National Standards Institute N509-1980 acceptance criterion of 99.95 percent.
