HEPA filtration definition

HEPA filtration means the high efficiency particulate air filtration found in respirators and vacuum systems capable of filtering particles greater than 0.3 micron in diameter with 99.97% efficiency, designed for use in asbestos-contaminated environments.

HEPA filtration means high efficiency particulate air filtration found in respirators and vacuum systems capable of filtering particles greater than or equal to three-tenths (0.3) microns in size, with 99.97 percent efficiency.

HEPA filtration means a filtering system capable of trapping and retaining at least 99.97 percent of all monodispersed particles 0.3 microns in diameter or larger.
