KN95 protective mask, FFP2 certified, GB standard, non-woven fabric, melt-blown fabric, ear loops, nose bridge clip

High-quality, disposable face mask with particulate filtering at 95 percent or greater filtration efficiency for particles down to 0.3 microns in size. Comfortable, light-weight mask with ear loops and adjustable nosepiece for secure fit and seal.

  • Filter performance – (must be ≥ X% efficient):
    ≥ 95%. Effectively filters out air pollution, dust, bacteria, odor, dust, pollen, and so on, protecting the respiratory system.
  • Test agent:
    NaC
  • Flow rate:
    85 L/min
  • Total inward leakage (TIL)* – tested on human subjects each performing exercises:
    ≤ 8% leakage (individual and Arithmetic mean)
  • Inhalation resistance – max pressure drop:
    ≤ 350 Pa
  • Flow rate:
    85/min
  • Exhalation resistance - max pressure drop:
    ≤ 250 Pa
  • Exhalation valve leakage requirement: Depressurization to 0 Pa ≥ 20 sec
  • Force applied:
    -1180 Pa
  • CO2 clearance requirement:
    ≤ 1%
  • 4-Layer Construction:
    For maximum filtration of particles
  • Optimal fitment:
    Three-dimensional cutting, fine stitching. The face mask fits tightly to the face.
  • Elastic ear loop:
    High-quality elastic ear loop, suitable for different face shapes and sizes. Does not slip, allows you to attach or remove quickly and easily.
