NIOSH has nine total acceptance classes, N95, N99, N100, R95, R99, R100, P95, P99, P100 structured by oil compatibility and filter efficiency.

The letter signifies how the filter checks in environments exposed to oil aerosols:

N95, N99, & N100. These filters are not to be used with oil aerosols. These ought to be Employed in environments exposed to particulates which never have oil. In several situations, the n- respirators may be reused many moments.

R95, R99, & R100. These filters are oil resistant. The r- respirators may be used in atmospheres containing particulates any strong or liquid hazard which includes oil-primarily based dangers. They're a single-time use masks.
