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?

It’s like walking through the rain with a 95% effectieve rainsuit. Yes you might have a wet spot in your neck or along your leg or whatever, but it’s still dryer than being out in a rainstorm without the suit.
