KN95 is actually a Chinese standard, which means "self-priming filter respiratory protective equipment for protecting all kinds of particulate matter". Since it is also "95", the filtration efficiency of KN95 is also about 95%. In fact, KN95 and N95 are basically the same, but the name and the country are different.
