How to choose a medical face mask?

Medical face masks are divided into ordinary medical masks, medical surgical masks and medical protective face masks, and their protection levels have been gradually increased.

1) Ordinary medical masks generally lack the filtration efficiency requirements for particles and bacteria, or the filtration efficiency requirements for particles and bacteria are lower than those for medical surgical masks and medical protective masks. Ordinary medical masks are generally ear-mounted, and can be used for disposable sanitary care in ordinary environments, or for blocking or protecting particles other than pathogenic microorganisms such as pollen.

2) The surgical face mask is divided into 3 layers, the outer layer has a water blocking effect, which can prevent droplets from entering the mask, the middle layer has a filtering effect, and the inner layer has a moisture absorption effect. Medical surgical masks are generally laced, which is suitable for basic protection of medical personnel or related personnel, as well as protection against blood, body fluids and splashes during invasive procedures.

Compared with ordinary medical face masks, medical surgical masks have a better barrier effect against respiratory infectious diseases, and have a better dustproof effect than ordinary medical masks. However, compared with medical protective masks, the surgical surgical masks have a slightly weaker protection level. .

3) Medical protective face masks are suitable for the protection of airborne respiratory infectious diseases, and have a very good barrier effect against dust and haze. The protection level is high among these types of masks. The N95 masks we often say fall into this category.

Even the protection effect of ordinary cheap medical masks is much better than that of various masks on the market. So is it better to choose a mask with a higher protection level?

of course not! Choose to wear according to the specific environment. Everything has its two sides, and masks are no exception. Masks with good protection function will also have relatively good airtightness. In plain words, it will be stuffy, and prolonged wearing will cause physical discomfort.
