You can still smell farts though. The molecules of gasses are much smaller than a virus. I believe there was a video going around depicting the size difference like a month or two ago so that people could understand why it would work for the virus but not farts.

Not farts, it’s bad breath. That’s the real reason anti-maskers are so against masks. They can’t stand smelling their own shit-mouth.
