简体中文Speaking of KN95 masks, everyone is familiar with it. In hospitals and other places where there are many germs, you can often see many people wearing KN95 masks. So how do KN95 masks prevent germs and other toxins from entering the human body?
From the earlier point of the KN95 mask material, the filter cloth it uses mainly absorbs bacteria and viruses and blocks pathogens. The dense filter layer uses N95 filter material to filter out particles, which can effectively block flying wipes, blood, body fluids and secretions.
Mask straps are two long straps that pass through the holes on both sides of the mask. The nose is clamped in the center of the upper part of the filter layer and placed between the dense layer and the filter layer. The material is metal or metal-plastic composite, which has both plasticity and certain strength, which is convenient for nose sealing when wearing.
It can be said that KN95 masks are good items to protect the mutual infection between medical staff and patients. Therefore, they must be made according to national requirements to achieve a bacterial filtration efficiency of more than 95%. This is the most important role of KN95 masks.
