The filter just has to say “95” and be from 3M.
95 means it filters out 95% of particles >0.5 microns.
“N’ means it is NOT oil resistant. “P” means its oil resistant.
N95 filters are exhausted, but there’s respirators and P95 filters available.
A respirator mask with a P95 filter will do the same thing as an N95, and oil resistant.
