The protective characteristics of different types of medical masks

Gauze masks: protective equipment to protect the respiratory tract from harmful dust, aerosols, microorganisms and dust typhoid. The anti-virus filtering effect is only 20-30%. Gauze masks cannot be used for medical protection, and are only used as ordinary dust masks.

Medical surgical mask: a medical mask worn by medical staff during invasive operations that can prevent the spread of blood, body fluids and splashes. Standard medical surgical masks are divided into 3 layers: the outer layer has a water blocking layer to prevent droplets from entering the mask; the middle layer has a filter layer that can block 90% of 0.3μm particles; the inner layer near the mouth and nose is used for moisture absorption.(Generally, the nose clip structure is on the outer layer of the medical surgical mask)

N95 medical protective masks: N95 masks can prevent infections caused by airborne infectious agents with a diameter of <5μm or close contact with droplet-borne   diseases of <1m. N95 medical protective masks can filter 95% of 0.3μm particles and have a barrier effect on viruses.
