KN95 Respirator Masks
NIOSH N95 masks are the US standard for respirator masks; KN95 masks are the Chinese standard for respirator face masks. In Europe FFP2, Australia P2, Korea KMOEL, and Japan DS masks are also highly similar to the US N95 and Chinese KN95. According to mask manufacturer 3M, “it is reasonable to consider” China’s KN95s “equivalent” to US N95s. Both N95 and KN95 masks are rated to capture 95% of 0.3 micron particles in the air.
