KN95 vs. N95 Breathability

The Chinese government tests KN95 masks on people to make sure they fit well and don’t leak much (less than 8% leakage). N95 masks are tested to see if the wearer can smell and taste certain things while wearing them. This shows KN95 masks focus more on a tight fit, while N95s are better for breathing.

What are the test standards for N95 and KN95 masks?

The CDC has a guide for N95 masks, including the NIOSH standard (a top standard for masks). KN95 masks follow the GB2626-2019 standard, approved in China. To sell KN95 masks in the U.S., they need FDA and NIOSH approval. If you wanna sell kn95 masks in Europe, You must need CE認證.

Which mask should I wear?

If you want a mask that’s easy to breathe through and protects well, go for N95. If you’re looking at cheap price and tight protection, KN95 could be better.

KN95 and N95 masks are quite similar, each with their benefits. If you need N95 masks or want to find a manufacturer, 正新集團 offers various styles. They supply N95 masks to hospitals in China and meet high standards for the Japanese market too.
