3M has a tool to check if they're authentic: https://www.3m.com/3M/en_US/safe-guard-us/
Regardless, I've read that the FIVE year quality date applies mostly to the latex STRAPS and not the N95 membranes.

Also, most people have no idea just how single-use PPE is meant to be used. The concept of reusing a single-use mask is laughable in any scenario where you're depending on it to protect your life. And you're handling it, then touching other surfaces!
We did a test in a college organic chemistry course where a coupple of people were dosed with a UV reactive dye...and by the end of a normal class, even with what we considered to be "proper" PPE usage, everything was coated. And that was touch-only. It was to teach us just how insidiously contamination can spread. So many procedures in 2020-2022 were "better than nothing"....but sadly, not by much. Theatrical posturing...which only fuels the opposite narrative, sadly.

That said, I've worn the 3M respirator masks since early 2020 for being in close quarters with other humans, air travel, road tripping through the dome (Red Route 1). And all other work in person that I had to do over the past 4 years - and never had COVID or the Flu or a cold.
So, high quality N95 masks (which are mostly closer to N97-N98) CAN protect and avoid transmission even when exposed. It's not truly about absolute avoidance 100% expectation but reducing any volume of exposure.. so tiny exposure, the body can much better deal with than bolus of exposure or time.. YMMV.
I don't wear these but my wife does (they are smaller for smaller faces to make a better seal) and she's had even more travel than I during the past 5 years (certainly more AIR complex travel) and she to has been any infection free since 2019.
