Surgical masks and ordinary medical masks have certain differences. The waterproof performance of surgical masks is generally higher than that of ordinary medical protective masks, which can prevent infections caused by blood in surgery or by the spraying of liquids, gas liquids and jets in experiments on doctors, or infections caused by laboratory personnel, etc. The protection ability against viruses is also relatively strong, and can be used to prevent the spread of diseases such as influenza and respiratory system, and can also prevent patients from virus to people. And ordinary medical masks waterproof and particle filtration effect requirements are low, that is, medical masks than surgical masks requirements are low, protection performance is poor, so we need to recognize the mark when buying or using, must try to use medical surgical masks for protection.
