  • Class N: zero oil resistance. A distinction is ready between N95, N99, and N100. The number after the letter designates the percentage of filtration of deferred particles.
  • Class R: face mask resistant to oil for around eight hours. Again, a distinction is ready between R95, R99, and R100.
  • Class P: a completely oil-resistant face mask. There are P95, P99, and P100 available.
