Different Countries Have Different Levels of Mask Protection

The epidemic has triggered a large demand for masks by medical staff and the public. There are many types of masks on the market, and the scope of application of different masks is different. Different types of masks follow different standards.

1. China

The face mask grades in China is divided into GB 2626-2019 respiratory protection self-priming filter particulate respirator, GB/T 32610-2016 technical specifications for daily protective masks, YY/T 0969-2013 disposable medical masks, YY 0469-2011 Technical requirements for medical surgical masks and GB 19083-2010 medical protective masks.

2. The United States

The American NIOSH standard classifies the filter material and filtration efficiency of masks, and this standard is the highest recognized in the world.

According to the filter material of the middle layer of the mask, it is divided into three types: N, R, P series, and each can be divided into three levels according to the filtration efficiency. N is used to protect against non-oily suspended particles. Generally, non-oily particles refer to coal dust, cement dust, acid mist, microorganisms, etc. The droplets produced by talking or coughing are not oily. R and P are used to protect non-oily and oily suspended particles.

The ASTM F2100 standard is a medical standard that divides masks into three face mask protection levels: low protection (Level 1), medium protection (Level 2) and high protection (Level 3). The higher the level, the better the protection performance. Level 1 and Level 2 masks are usually called procedure masks; Level 3 masks can be used in the operating room, also called surgical masks. When the chance of exposure to the virus is particularly high, a higher level of protection should be selected.

3. Europe

For masks in the European Union, according to the tested particle penetration rate, the face mask levels are divided into P1 (FFP1), P2 (FFP2) and P3 (FFP3). The minimum filtering effect of FFP1 is ≥80%, the minimum filtering effect of FFP2 is ≥94%, and the minimum filtering effect of FFP3 is Effect ≥97%
