Dust mask conforming to the national standard GB2626-2006 "Respiratory protective equipment, self-priming filter type anti-particle respirator" (strictly speaking, it should be called respirator)

It can prevent dust above 75 nanometers.

1 mm = 1000 μm

1 micron = 1000 nm

National classification of particulate matter protection

Anti-oily particulate matter (dust, smoke, microorganisms, etc.)

The effective protection rate of KN100 is over 99.97%.

The effective protection rate of KN95 is over 95%.
