In fact, there are not so many types of masks in hospitals. Generally, there are only disposable medical masks, medical surgical masks and medical protective masks. So, how to distinguish disposable medical masks, medical surgical masks, and medical protective masks? What are their respective functions?
1. Distinguish from the packaging
Generally, these three kinds of masks have different technical standards. "Disposable medical masks" are (YY/T0969-2013), "Medical surgical masks" are (YY0469-2011) and "Medical protective masks" are (GB19038-2010) . You can judge which type of mask the product belongs to by checking the implementation standards marked on the outer packaging of the product, and the respective names will also be written on the packaging.
2. Different mask shapes
Disposable medical masks and medical surgical masks are rectangular in shape, with ear-wearing and strap-on types. The vast majority of medical protective masks are duckbill-shaped, which is easier to distinguish.


3. The performance is different
All three types of masks can filter bacteria, but they are different in terms of water resistance and particle filtration efficiency. First of all, disposable medical masks do not have performance requirements for water resistance and particle filtration efficiency, while medical surgical masks and medical protective masks have requirements. Secondly, the waterproof performance of medical surgical masks is higher than that of medical protective masks, which can prevent the infection of doctors from splashes of blood and body fluids produced during surgery.
Finally, medical protective masks must have the main functions of surgical masks at the same time, including the efficiency of bacterial filtration and the function of blocking pressured liquid splashes, as well as respiratory protection, that is, to protect the wearer's breathing safety. Moreover, the particle filtration efficiency of medical protective masks is higher than that of medical surgical masks.
What are the functions of these three masks?
First of all, disposable medical masks are only suitable for blocking pollutants exhaled from the operator’s mouth and nasal cavity during general diagnosis and treatment operations, that is, they are used when there is no invasive operation. Clinical hospital staff generally wear this mask during work. It can basically meet the needs of our ordinary people.
Secondly, because of its good waterproof performance and particle filtering efficiency, medical surgical masks are suitable for operation, laser treatment, isolation, and dental or other medical operations, as well as air or droplet-borne diseases or wear; mainly to meet the needs of hospital surgical operators use.
Medical protective masks have good particle filtration efficiency and can effectively filter viruses, so they are suitable for occupational protection of medical staff when they come into contact with patients with airborne and droplet-borne diseases or when they come into contact with infectious microorganisms.
