NIOSH has 9 whole acceptance lessons, N95, N99, N100, R95, R99, R100, P95, P99, P100 organized by oil compatibility and filter performance.

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

N95, N99, & N100. These filters are certainly not to be used with oil aerosols. These must be Employed in environments exposed to particulates which never consist of oil. In several cases, the n- respirators can be reused several situations.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be employed in atmospheres containing particulates any sound or liquid hazard like oil-centered hazards. They are just one-time use masks.

P95, P99, & P100. These filters are oil evidence. These respirators may be used in almost any setting exposed to harmful particulates. The p- respirators are matter to time of use limitations.
