The masks we often mention are generally KN95 and N95.The former is the Chinese standard and the latter is the American standard. However, the protection levels of the two masks are equivalent, and the protection efficiency against non-oily particles is not less than 95%.This is already a mask with a very high level of protection on the market.

But if the elderly in your family have low resistance, or your working environment is very dangerous, and you want to buy a mask with a higher protection level, then you choose to look at the FFP3 mask.

（figure 2：FFP3)

FFP3 masks refer to masks that meet the European (CEEN149:2001) standards. The European standards for protective masks are divided into three levels: FFP1, FFP2, and FFP3.FFP3 is an evaluation level, with a particle filtration efficiency of 97%, which exceeds the KN95 and N95 (95%) levels. It is the highest protection level in the European standard, and the suction resistance is also the largest.If the comparison is based on the protection effect, then FFP3>FFP2=N95=KN95=KF94>KN90.

At present, the quality of products on the market varies from good to bad, even if you spend money to buy a product, it is likely to be substandard.Therefore, be sure to check its certificate and qualifications when purchasing.For example, KIEYYUEL is a company that integrates processing, R&D, production and sales. Its products include masks, gloves and protective clothing and other more than ten items.You can find the FFP3 mask on its official website.

This FFP3 mask has a five-layer filter structure, and the particulate matter filter is more than 99%.The design of the exhalation valve is very delicate, with several layers of flaps. When inhaling, the flap will close tightly to ensure that no particles enter. When you exhale, the flap will open, letting out the hot and humid air.And the more important point is the qualifications and certificates
