Why make the claim that n95s don't filter viruses and then say that they do indeed capture viruses?

Also yes the filtration fades but there's data out there showing 40 hours of use on KF94s still showing filtration percentages in the low 90s.

You misunderstood or I was not clear. N95s do filter viruses when used properly and still within their rated window of use.
