These KN95 Face Masks are not meant for hospital front lines, but they are similar to the N95.
A few of the differences N95s and KN95s are both rated to capture 95% of particles, although only KN95 masks are required to pass fit tests. N95 masks have slightly stronger requirements for breathability.N95 masks are the US standards for respirator masks; KN95 masks are the Chinese standards for masks. These are the requirements that the US National Institute for Occupational Safety and Health N95 masks have slightly stricter requirements for pressure drop while inhaling. That means they’re required to be slightly more breathable than KN95 masks.
