Regarding mask standards, each country has its own mask standards.Generally speaking: KN95 is a Chinese standard, one of the levels specified in GB2626-2006; N95 is an American standard, one of the levels specified in 42CFR84.he protection levels of the two are equivalent, and the protection efficiency for non-oily particles is not less than 95%.

(figure 1)

The technical requirements and test methods of these two levels are basically the same, but they belong to the standards of different countries.The protection levels of the two are equivalent, and the protection efficiency for non-oily particles is not less than 95%.If the comparison is based on the protection effect, then FFP3>FFP2=N95=KN95=KF94>KN90.

KN95/N95 masks have better protective effects than medical surgical masks and disposable medical masks.It is generally recommended for on-site investigation, sampling and testing personnel. The public can also wear it in highly crowded places or closed public places.Ordinary people generally don't use KN95/N95 masks, as long as they are ordinary facial masks. For example, KIEYYUEL masks are a good choice, and more importantly, there are dual certifications of FDA and CE.
