How to choose the correct mask?
Choose the right mask

If you are going to a public place and are not in contact with the patient, it is sufficient to wear a medical surgical mask. You do not have to overprotect it.

When wearing a medical mask, you should choose the appropriate level type according to the type of pollutant transmission and risk, not too high or too low. Although the protective effect of medical protective masks with high protection level is better, due to the high filter grade, good adhesion, and higher respiratory resistance, long-term wearing will increase the respiratory burden and cause discomfort such as difficulty in breathing.

Medical surgical masks and medical protective masks can block the pollution caused by the splash of blood and body fluids, but if you really need to block the pollution of airborne particles and pathogenic microorganisms, please choose to wear a medical protective mask.
