Medical surgical mask, in line with YY0469 standard, the mask to prevent pathogenic microorganisms, body fluids, particles and other direct through to provide a physical barrier, bacterial filtration efficiency of 95%, non-oily particulate filtration efficiency of 30%. Is the operating room and other body fluids, blood splash risk environment, commonly used medical masks, can block blood, body fluids through the mask pollution wearer. It also helps reduce your own saliva and respiratory secretions from splashing on others, thereby preventing infection of others.

Because surgical masks and face stickers are relatively loose and not tight, surgical masks cannot completely protect bacteria, viruses and other contaminants from entering the wearer's mouth and nose.


Appearance, structure and size, nose clip, mouth and nose strip, synthetic blood penetration, bacterial filtration efficiency, particle filtration efficiency, pressure difference, flame retardant performance, microbial residue, etc.


Medical protective masks should not only meet the filtration efficiency of more than 95% of non-oily particles, but also be suitable for medical clinical work environment, blocking droplets, blood, body fluids, secretions and other self-priming filter medical protective masks, such as 3M 1860/1860s, 9132 and so on. The detection standard of medical surgical masks is YY, and the bacterial filtration efficiency should not be less than 95%. Compared with medical surgical masks, medical nursing masks have no requirements on the performance of resisting blood or infectious body fluid splash, but as protection, they can be used in non-personnel intensive places.‍
