Filtering capacity versus "breathability."

But the fit likewise makes a big difference. Even while we can't approach an N95 (or other specific respirators) in creating a seal as with a properly fitted mask there are still modifications that can be made to ordinary face coverings. Attempts to make it fit closely around the top of the nose and cheeks with moldable nose wires and the ability to snug around the ears can make a significant difference.

So, far, the filtering capacity of various materials versus breathability/comfort has been looked at, but the rest is the wild wild West.

Good luck to those who may try to tackle this, But the first thing they need to do is crack down on companies and ads suggesting that plastic face shields alone suffice. Like this one: ( )
