One of the most common questions I am asked as someone in the PPE space is this question of the differences and similarities in these face masks. I like to try to keep the explanations short and to the point, first thing is that N95 masks are the US standards for respirator masks, KN95 masks are the Chinese standards for masks. KN95 masks are required to pass fit tests and N95 are not though they do generally have a fit class in hospitals etc. to learn to effectively use them.
