“I believe the N95 are only for dust particulate and will not absorb the flu type viruses...You need a biomask for viral type airborne diseases.”
Yes and no. I thought the same, but while viruses are really, really, puny, often they are transmitted through far larger water droplets. Any, the claim is out there that N95 masks are one of the essentials for virus protection, but obviously not the best, by far.
The N95 has to fit you properly. I’ve seen pics of people in China wearing surgical masks under the N95, which looked like a good extra precaution.
