I got positive last month. I feel that for a long time in the future, for our health, everyone must develop a good habit of wearing masks. Masks will also become indispensable for us. One of the items.

There are not only many types of masks on the market, but also different prices. Let’s talk about the classification of masks in detail.

According to the management of medical devices, masks are divided into three types. The order of protection levels is medical protective masks > surgical masks > medical masks (disposable medical masks), all of which are managed according to Class 2 medical device products . Ordinary gauze masks, cotton and cloth masks are not regulated as medical devices.

There are mainly the following types of masks according to their functions:

1. Ordinary masks (non-medical):

Such as cotton masks, activated carbon masks, gauze masks, etc. , can be used to prevent freezing, dust, and partial anti-smog, but it cannot be used to prevent the spread of bacteria and viruses.

2. Ordinary medical masks:

The protective effect against pathogenic microorganisms is not accurate and can be used for one-time health care in ordinary environments, or for particles other than pathogenic microorganisms. Such as blocking or protecting pollen. It is less protective than a medical surgical mask and can be used in non-dense crowds.

3. Medical surgical masks:

The protective effect is much better than ordinary masks. They were used more in hospitals before and are often used in respiratory departments and surgeries. They can be used to prevent germs and Bacteria spread. It is suitable for basic protection of medical personnel or related personnel, as well as protection to prevent the spread of blood, body fluids and splashes during invasive operations.

4. KN95/N95:

N95 is not entirely a medical protective mask. It generally includes N95 medical protective masks and N95 industrial masks.

Medical protective N95 masks are suitable for medical personnel and related staff to protect against airborne respiratory infectious diseases, with a high level of protection. N95 is the American NIOSH dust mask standard, and the domestic standard is KN95. The detailed parameters are consistent with the domestic KN95.

N95 masks are more reliable in preventing smog. PM2.5, the main component of smog, is non-oily particulate matter. It can also be used to protect against the spread of bacteria and viruses. It is the daily mask with the highest level of protection currently available. KN95 and N95 only have different names. The protection levels of masks produced according to these two standards are exactly the same, and there is no difference in protective effect.

Their protection levels are: KN95/N95 masks ≈ medical surgical masks > ordinary medical masks > ordinary masks.

5. Children's masks

Suitable for children aged 6-14 years old, choose according to size and face shape. Fits the face, has high sealing performance, is safe and comfortable.

Children’s masks also have national standards. Pay attention to choosing masks that comply with the children’s national standard GB/T 38880-2020 and have a bacterial filtration efficiency of ≥95%.

?Be sure to look at the code (implementation standard) when purchasing. If there is no code, don’t buy it?

In some situations where the risk of virus infection is high, it is strongly recommended to wear medical protective masks. Yes The mask with the highest protection specifications?
