How to choose a mask
The filtration efficiency of a mask is one of the important indicators to measure its protective ability. The higher the filtration efficiency, the better the mask’s ability to filter tiny particles such as bacteria and viruses. The stronger. N95 masks are mainly used to protect against particles in the air, such as smoke, dust, bacteria, viruses, etc. However, the breathing resistance of N95 masks is relatively large, and wearing them for too long can cause discomfort.
KN95 masks refer to masks that meet Chinese national standards, and their filtration efficiency has reached above 95. However, compared with N95 masks, KN95 masks have smaller breathing resistance and are more comfortable to wear. However, since the standards of KN95 masks are different from N95 masks, there are certain differences in their protective capabilities. Medical masks refer to masks used in the medical and health field, and their filtration efficiency is generally around 70.
