The 95 refers to the percentage of airborne particles that are filtered for the wearer of the mask.
The following was copied from a Google search.......
The different ratings in place for respirators indicate how well the mask would protect against oils and are rated as N, R, or P. ... Respirators that filter out 95 percent of airborne particles are given a 95 rating, so N95 respirator filters out 95 percent of airborne particles but is not resistant to oil.
