Good morning, the difference between N95 and N99 is the same as between FFP2 and FFP3, you might find this video interesting: th-cam.com/video/x6GW_OJAQ6I/w-d-xo.html
Good morning. Surgical masks are very wide and do not fit the face completely, so they have a factor of 0 and do not protect the wearer. An ffp3, on the other hand, fits fully and has a factor of 100.
amazing video, thank you! exactly what i was looking for
I have 5 of them from the hospital. Pretty good and well made masks 👍
I wonder what the fit quality is worth for people who have a beard? Is it like people who go diving? Shave it off or lose effectiveness?
Good morning, yes, It's necessary to Shave the beard off.
What is the equivalent "Chinese" standard? FFP2 is K/N95 right? So what is FFP3?
Good morning, the equivalent is KN99 mask.
@@GVSBlog There's no equivalent .GB2626 has KN90,KN95,KN100
how is this related/compared to N95 or KN95 masks?

fit factor of 0 doesn't make sense.
