How Should I Choose A Medical Mask?

Medical masks are generally divided into disposable medical masks, medical surgical masks and medical protective masks. Different types of medical masks have different technical standards and different shapes.

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 medical surgical masks and medical protective masks. Ordinary medical masks are generally ear-hanging, which can be used for one-time hygiene care in ordinary environments, or for the blocking or protection of particles other than pathogenic microorganisms such as pollen.

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

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

Even the most common and cheapest medical masks have a much better protective effect than the various masks on the market. So, do masks choose the higher the protection level, the better?

of course not! Choose to wear according to the specific environment. Everything has its two sides, and masks are no exception. Masks with better protection function will also have better airtightness. In easy-to-understand words, it will be more boring, and wearing it for a long time will cause physical discomfort.
