It is not always about filtering out the virus itself, but more often filtering out the aerosolized droplet that the virus is suspended in.

and those droplets are pretty nasty anyway without without a virus

But the virus is always attached to droplets. It doesn't just fly around on its own. The n95 and kn95 do a pretty good job of blocking it. Plus it's about how much viral load you get. The more you can limit what you breathe in the better.

Exactly, this virus does not do well exposed to the air, it depends on being suspended in a droplet to keep it moist, so all you really need to do is block the microscopic droplets that the virus particles are suspended in. Then use a reasonably amount of caution handling the mask when you take it off. My personal method involves rotating through 3-4 N95 masks which I keep in my car, that way by the time I am back to reusing the first one any droplets on the outside of the mask have had time to dry out and get baked in the sun for a while.

Now that the supply of n95s is coming back, 3M is going to want to reclaim their monopoly on selling to medical establishments, but I'll be sticking with the kn95s. Also easier to carry them around because they fold flat.
I just bought a box of 50 3M N95s for $.72 ea from Amazon and they come individually wrapped and fold flat. Should last me a long time since I don't need to wear a mask often.

I find it so interesting when I read or listen to many many people, I suppose they are smart, telling all different ways to protect themselves, ad nauseum.
This whole pandemic is opinion driven, media, politicians, doctors, virologists, movie stars, seems the list of know- it -alls is endless. And hundreds if not thousands of these people telling all us know nothings what to do, how to act etc. And we're no better off we were 18 months ago.
Is it possible that 7 billion people are insane listening to the talking heads over and over and over again?
Humans.... we are indeed a weird animal.

Not a bad comparison, now imagine the wires of the fence moving back and forth at 2000 mph. 95 percent of the mosquitos would be stopped. Not quite the analogy used to explain it to me by a research chemical engineer at 3M but close.
