What Is the Difference Between KN95 P2 and N95 Masks?
KN95, N95, P2 and FPP2 are all standards that different countries use when rating masks efficiency.
- KN95 is the Chinese standard. The K represents China
- N95 is the American standard. NIOSH air-filtration rating.
- P2 is Australia and New Zealand Standard
- FFP2 is the European standard
All the above masks, in reality, are the same. They just use different air-filtration rating codes.
What do N95 and KN95 Mean on a Mask?
N95 and KN95 indicate that the mask or respirator will block up to 95% of airborne particles that measure over 0.3 microns or the width of a human hair. The P2 and FFP2 will block up to 94% of airborne particulates.
NIOSH stands for National Institute for Occupational Safety and Health. It is the USA’s classification rating for air filtering respirators. There are nine NIOSH classifications that are based on a mix of respirator series and effectiveness.
It is expected that all certified masks with the above markings will perform to their tested standards.
Other P2, KN95, N95 and FFP2 Respirator Tests
Some of the terms used on testing are called Filter performance, Test Agent, Total inward leakage (TIL) and inhalation resistance.
Always refer to the respirator mask details on the item.
