The letter signifies how the filter tests in environments uncovered to oil aerosols:

N95, N99, & N100. These filters aren’t to be used with oil aerosols. These must be utilized in environments uncovered to particulates which don’t comprise oil. In many cases, the n- respirators may be reused a number of times.

R95, R99, & R100. These filters are oil resistant. The r- respirators can be utilized in atmospheres containing particulates any stable or liquid hazard including oil-based hazards. These are one-time use masks.
