The shape of the mask is different:

Disposable medical masks and medical surgical masks are rectangular in shape, including ear wearing type and bandage type. And the vast majority of medical protective masks are duckbill shaped, which is easier to distinguish.

The performance is different:

These three kinds of masks can filter bacteria, but they are different in water resistance and particle filtration efficiency. First of all, disposable medical masks do not have the requirements of water resistance and particle filtration efficiency, while medical surgical masks and medical protective masks have the requirements. Secondly, the waterproof performance of the medical surgical mask is higher than that of the medical protective mask, which can prevent the blood and body fluid splashes produced in the operation from infecting doctors.

Finally, the medical protective mask must also have the main functions of surgical mask, including the function of bacteria filtration efficiency and barrier of liquid splashes with pressure, as well as the function of respiratory protection, that is, to protect the respiratory safety of the wearer. Moreover, the filtration efficiency of medical protective mask is higher than that of medical surgical mask.

What are the functions of these three kinds of masks?

First of all, disposable medical mask is only suitable for blocking the pollutants exhaled by the operator's mouth and nose during general diagnosis and treatment operation, that is, it is used when there is no invasive operation. Clinical hospital staff generally wear this kind of mask at work. It can basically meet the needs of our ordinary people.

Secondly, medical surgical masks are suitable for surgery, laser treatment, isolation, dentistry or other medical operations, as well as air or droplet borne diseases or wear because of their good waterproof performance and particle filtration efficiency; It mainly meets the needs of hospital operators.

Because of its good particle filtration efficiency and effective virus filtration, medical protective masks are suitable for occupational protection when medical personnel contact with patients with airborne and droplet borne diseases or when they contact with infectious microorganisms.
