According to mask manufacturer 3M, “it is reasonable to consider” China’s KN95s “equivalent” to US N95s. Mask standards for Europe (FFP2), Australia (P2), Korea (KMOEL), and Japan (DS) are also highly similar.

N95s and KN95s are both rated to capture 95% of particles. Among the minor differences, only KN95 masks are required to pass fit tests, while N95 masks have slightly stronger breathability standards.
