Different countries for respirator filter efficiency has its own standard, masks usually has N, KN, KF or FFP, these letters refers to the different national standard classification for respirator filter efficiency, masks on KN is one of China's standard, N represents the American standard, KF is South Korea standard, FFP is European standard. KN is the Chinese standard, and its detection technique is the same as that in the United States. According to China's gb2626-2006 standard, masks are divided into KN class and KP class. KN means masks are suitable for filtering non-oily particles, while KP means masks are suitable for filtering oily and non-oily particles. The number after the letter represents the protection level of the mask. The larger the number, the higher the protection level, which is the filtering effect of 0.3 micron particles. Another common type of mask is the KN90, which is slightly lower than the KN95 and is ok. N is an American standard mask. The filter material and filtration efficiency of the mask are graded by the national institute of occupational safety and health (NIOSH). It is also the filtering effect of 0.3 micron particulate matter. The filtration efficiency of N95 mask for non-oily particles must be above 95%, which is similar to the national standard KN95. KF is a south Korean standard mask, and the KF series standard is set by South Korea's Ministry of Food and drug administration
