The theory of medical N95 and N95 masks

Both medical N95 and N95 respirators have respiratory protection functions against particles suspended in the air. However, because medical N95 is used in a medical environment, the medical mask worn must be able to block the droplets and bacteria generated by the wearer’s breathing and speech from entering the surgical environment, and at the same time resist the penetration of pressured blood, and the mask itself must be It is hygienic, so the number of microorganisms on the original mask should not exceed the standard, and the exhalation valve is not allowed on the mask;

The N95 protective mask does not have the function of a medical surgical mask. It can protect against influenza viruses, infectious droplets or other harmful particles in the air. It is sufficient to use ordinary N95 protective masks or protective masks with equivalent performance.
