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, the difference between N95 and N99 is the same as between FFP2 and FFP3, you might find this video interesting: kzbin.info/www/bejne/rmeqiJKFf6aEbKs

fit factor of 0 doesn't make sense.

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.
