Surgical masks are used for basic protection of medical personnel or associated personnel, as well as protection against the spread of blood, body fluids and spatter during invasive operations.

The production of medical surgical mask is mainly in the clean environment with a cleanliness level of less than 100,000, which is suitable for operating room work, nursing patients with low immune function and body cavity puncture.

Surgical masks can block most bacteria and some viruses, preventing health workers from becoming infected and from exhaling microbes that pose a threat to patients undergoing surgery.

Surgical masks are required to filter bacteria at least 95 percent efficiently.

Disposable surgical masks should also be issued to suspicious respiratory patients to prevent the threat of infection to other hospital staff, reduce the risk of cross-infection, but not as effective as medical protective masks to avoid infection.
