KN95 certified, similar to the American N95 and European FFP2 certifications. KN95 is an industry-standard and means that the mask provides the intended effectiveness of filtering 95 percent of particles with a mass median diameter of 0.3 micrometers. Therefore, our mask can protect you well from PM10, PM2.5, and even smaller particles.
It can also help reduce exposure to biological substances, such as bacteria and germs.
