KN95 Mask with Valve Safety Protective Mask PM2.5 N95 Fliter Anti Dust Pollution Earloop Face Mask Flu Respirator
KN95 mask can isolate smaller particles, and fit tighter to the face, it is not easy to leak air from the periphery, and the filtration efficiency of particulate matter can reach 95% under standard conditions.
The n95 mask is not a disposable mask. In this special case (resource shortage), it can be reused. But there are conditions:
1. When n95 receives contamination such as saliva, blood, tears and other body fluids, it must be replaced

3.The third layer: activated carbon cloth, benzene and a smaller function of filtering dust microns
4.The fourth layer: filter density, smaller material
5.The fifth layer: Spunbond cloth, filter out all kinds of harmful substances;
Profession Protection Filter (PM2.5) traps and filters air molecules from deadly flu, and bacteria. Filters of bacteria , dust, chemicals, particles, pollen and smoke.
