To me I just don’t see how this would work or filter anything. So it 95% is blocked, then 5% of the particulate will pass through the filter and cause harm. It’s like saying you are on a submarine and saying it’s 95% sealed. Then the rest would fill up the submarine then you’d end up dead. Is there something else I’m missing here?

Viral load matters. although we’re still not 100% sure why one person gets infected while another one may not, we have definitively proved that inhaling 100% of the virus particles is way way way more likely to cause a disease than inhaling 5% of them.
Your submarine metaphor would make sense if you added in that the submarine has a bailing system that can tolerate leaks and stop them from getting worse.
