respirator
noun
Note: Particulate respirator masks are only able to filter out particles and are not effective against gases or vapors. A numerical rating (such as 95 or 99) is sometimes assigned to such a respirator to indicate the percentage of airborne particles filtered. A letter may also be assigned to indicate whether it is somewhat resistant (R), not resistant (NR), or strongly resistant (P) to the degrading effects of oil on proper respirator function.
