[PLUG-TALK] Masks with ear loops ... NIOSH?

[Brian Stanaland]

This is interesting:

What’s the difference between N95 and KN95 face masks?

We're glad you asked: KN95s are just another kind of particulate respirator
mask—like N95—and they function the same way (again, with that 95%
filtration). The primary difference is that N95 is a standard for the USA,
whereas KN95 is China's version—meaning the certification process is a bit
different. While N95s have to be certified by the National Institute for
Occupational Safety and Health (NIOSH), KN95s need approval from the FDA.
