Maybe this is another good reason to wear a mask!
Particulate matter in wood smoke is supposedly around 0.4–0.7 μm which which is a little bigger than a SARS-Cov2 virus particle at 0.1 μm so an N95 mask should handle both (not sure about paper surgical masks, almost certainly better than nothing for wood smoke).
- XMPPwocky 6y agoAFAIK, the mechanism of action of paper surgical masks, and cloth masks, is not by catching particles of that size, but primarily by catching larger droplets and by disrupting forward airflow on exhalation. So their usefulness for smoke would seem questionable.
