I wonder what the number is for people who wear respirators for dust/fumes. There's the paper masks people are most familiar with and the charcoal canisters for working with chemicals. Since it's sealed off would it be even higher than a motorcycle helmet?

There’s probably all kinds of confounding factors here, but on high pollution days (code purple air quality) when I’m bicycling I need to take my N95 mask off every few minutes for “fresh air.”
