I dunno makes sense enough to me. Air through filter good, air not through filter bad. How many lives you saved with 3 rubber bands lately?

- craftinator 6y agoI think the problem is more about how this will change peoples behavior. See xbkingx's comment above. It's the same problem that football players have when compared to rugby players; they think they are safer because they have greater protection, so they take greater risks.

Agreed that calling it an n95 equivalent without any evidence might be a stretch though. And yes other papers looked at it with a seal. Still would be interesting to see a surgical vs. sealed surgical comparison.
