The mask must have at least three layers to work.
The most common medical Surgical Mask is a rectangular mask, which does not fit closely with the face. All masks are divided into three layers, namely outer layer, middle layer, and inner layer, the outer layer has a waterproof effect; the middle layer has
Filtration, 90% of particles larger than 5 microns can be blocked; the inner layer is used to absorb moisture. The main difference between protective masks and medical surgical masks is the intermediate adsorption layer.
When the saliva droplets in the mouth are splashed outward, the outermost layer of the mask can play a certain blocking role, and bacteria and viruses in the air can be adsorbed in the middle layer, which plays an effective filtering role to ensure
We breathe clean air.
How long does the mask need to be replaced?
The study found that the N95 mask was worn for 2 days, the filtering effect remained above 95%, and the respiratory resistance did not change much; the filtering effect was reduced to 94.7% after wearing for 3 days.
Can wearing multiple masks better prevent new coronavirus infections?
As far as Medical masks are concerned, any qualified product that is properly worn requires only one to achieve the desired protective effect. The higher the level of protection effect, the greater the breathing resistance of the mask. When we wear
The feeling of experience will be a little bit worse, and the sense of comfort will also be reduced. When people wear a mask and breathe in, the mask will have a certain resistance to the flow of air. When the breathing resistance is too large, people will feel dizzy,
Chest tightness and other discomforts. If you wear an improper mask, not only will it make you breathless, but the air cannot enter the nasal cavity from the front, but only from the side, but it will not play a preventive role.
Therefore, as long as it is a qualified product, medical protective masks and general medical surgical masks can effectively prevent new coronavirus infections, that is, prevent the spread of pathogens carried by respiratory droplets.
