What is the difference between n95 and kn95 masks? Which one is better?

Recently, there has been a new situation with Wuhan pneumonia, that is, the Wuhan "Red Cross". I will not go into detail about the details here (you can see it on your mobile phone), but what about N95 masks and kn95 masks? Which one is better? What is the difference between n95 and kn95 masks? Which one is better? The editor would like to share this with you after consulting some information!

What is the difference between n95 and kn95 masks? Which one is better?

The N95 mask is one of the nine types of anti-particle masks certified by the US NIOSH . "N" means non-oily particles; "95" means that under the testing conditions specified by NIOSH standards, the filtration efficiency reaches 95%.

KN95 masks comply with China's GB 2626 mandatory standard, with a non-oily particle filtration efficiency of ≥95%.

The testing methods for the filtration efficiency of these two levels of masks are exactly the same! The filtration efficiency level is consistent! KN95 meets the same requirements as N95, but KN95 meets Chinese standards while N95 meets US standards.

To put it bluntly, the difference between N95 and KN95 is not that the latter is unqualified, but that N95 is certified by the US NIOSH and KN95 is China's GB2626 mandatory certification. The filtration efficiency of both for non-oily particles is ≥95%.

The official response from the Hubei Red Cross Foundation: It was a typo, KN95 was written as N95. Even so, I believe you made a typo. The two masks have the same level of protection, and KN95 can meet the requirements just like N95. With an extra k, why can’t it be used for front-line protection?
