Protective performance of disposable medical masks

Disposable masks usually take 6-8 hours. After this time, it needs to be replaced. It should be noted that both sides of the mask cannot be replaced. Many people ask why the outer layer of the mask accumulates a lot of dust, bacteria and other dust in the outside air, which hinders the user's breathing. If replaced, the outer layer of dirt into the respiratory tract, affect human health.

Disposable mask is also a common name. In short, medical disposable masks can be divided into: medical protective masks, medical surgical masks and general medical masks.

Which kind of protective mask is good? The protective grade of medical mask is low. From the point of view of production specifications, this kind of mask is generally lack of filtration power requirements for particles and bacteria. Therefore, the general medical mask is only suitable for blocking the saliva exhaled from the mouth and nose. The medical surgical mask with medium protection level can block most bacteria and some viruses, which can not only prevent people from being infected, but also avoid some bacteria in the exhaled gas.

Respiratory protection can only reduce the risk of disease, but can not completely eliminate the risk. We should know that prevention and treatment are sometimes two things, reducing risk and eliminating risk are two things. Medical protective masks can not completely isolate pathogens. According to the protection power and scope of application, medical disposable mask manufacturers are mainly divided into medical general mask, medical surgical mask and medical protective mask.
