EPM 2000 has been developed and selected by the U.S. Environmental Protection Agency (EPA) for use in high volume air sampling equipment that collects atmospheric particulates and aerosols. Whatman EPM 2000 was selected by the EPA to be the standard filter for use in the nationwide network of HiVol air samplers. Sheets are individually numbered to facilitate identification.
