What’s the difference between N95 and KN95 standards?

N95s and KN95s are both rated to capture 95% of particles, although only KN95 masks are required to pass fit tests. N95 masks have marginally better requirements for breathability. With regard to filtration specifications, N95 and KN95 respirator masks are the same. Both masks are rated to capture 95% of microscopic particles (as small as 0.3 micron particles).
