Particulate Filtration Efficiency>99  Face Mask
  • FACE MASK N99 N95 FFP3 Protect Yourself From Viruses

    Just like an N95 mask, it doesnt filter out oil and oil based pollutants but filter PM 10, 2.5 and 0.3 microns in size. However, the filtering capacity is more than that of N95. Yes, N 99 mask is better than N95 masks simply because N99 has a slightly higher filtration rate of particulate matter than N95.

  • Particle Filtration Efficiency (PFE) Test Nelson labs

    Particle Filtration Efficiency (PFE) The Particle Filtration Efficiency (PFE) test evaluates the nonviable particle retention or filtration efficiency of filter media and other filtration devices at sub micron levels. This test is performed on face masks and all filter material that allows 1 cubic foot per minute (CFM) flow to pass through it.
