What’s the difference between N95, KN95, FFP2 and KF94 mask rating?

The N95 mask has a full name of NIOSH-approved N95 respirator, which means these respirators are tested of 95% filtration and certified by the U.S. National Institute of Occupational Safety and Health (NIOSH). And the KN95, FFP2 and KF94 mask is as effective as NIOSH-certified N95 mask with the same filtration efficiency, but are tested by different nation criteria. The KN95 respirator is a particulate-filtering mask tested using the China criteria. The FFP2 is a filtering facepiece score of 94% filter capacity approved by Europe, and the KF94 is tested by Korea criteria.
To simply put, we could put these respirators into an equation as below:

N100 (99.97%) = FFP3 (99.95%) > N95 (95%) = KN95 (95%) = FFP2 (94%) = KF94 (94%) > KN90 (90%).
