The Differences Between N95 and KN95 Masks

With the pandemic, health professionals are recommending we wear a face mask or covering in public.


What is the Same in N95 and KN95 Masks?

They are both face masks/respirators that filter out airborne particulates. They both function the same and have the same efficacy. They both prevent 95% of airborne particulates from getting through the mask. They’re also both medical grade non-woven face masks. They both have rigorous testing and standards.


They look different than the white or blue rectangular, disposable surgical masks we usually associate with medical professionals. They’re rounded, usually with a wire molded to fit the mask tightly around your nose.


What are the Differences Between N95 and KN95 Masks?

Mainly the testing and standard requirements. Chinese testing for KN95 is slightly more rigorous than U.S. testing for N95 masks. As mentioned above, China tests for inward leakage and have a C02 clearance requirement. The force used in testing for KN95 masks is roughly 4 times higher than in N95 masks, as you read above.


How Effective Are They at Blocking Out Viruses?

They both prevent 95% of airborne particulates, including viruses, from going inside and out of the mask, so unlike other face coverings, they also protect the wearer from airborne droplets (coughs and sneezes).
