We should fully play the role of masks. We should still understand the defense. The degree of protection of the dust mask. Let's take a closer look at it.

       According to the protection standards of dust masks, the state currently divides the dust mask into three grades: KN100, KN95, and KN90. 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%.

KN90 has an effective protection rate of 590 or more.

Oil-repellent particulate matter and non-oily particulate matter (dust, smoke, mist, microorganisms) for particles above 185 nm

The effective protection rate of KP100 is over 99.97%.
