People who have not tested the air tightness after wearing N95 masks may be in danger

Not everyone can achieve good results when wearing N95 masks, especially if the air tightness test is not performed before wearing N95 standard protective masks. The air tightness test does not meet the standard, even if you wear a mask, it will not achieve the effect.

Many people wear it incorrectly, the air tightness is not good, and there may be some obvious gaps. In this way, after wearing an N95 mask, the virus will also spread through these gaps, and it will also increase the risk of disease. Therefore, air tightness testing is required.

This shows that it is indeed necessary to wear N95 masks during the new coronavirus epidemic. However, there is a shortage of N95 masks on the market. If you can’t buy N95 masks, you can also choose medical masks, which can also achieve the protective effect.
