The mask that you would wear to protect yourself from wildfire smoke is not some flimsy surgical mask. Those only minimized aerosols coming out of your mouth, it's not a filter, it doesn't make wildfire smoke air safer to breath.
Right, I didn't try to imply the same masks, but there are so many options for cutting back on wildfire smoke particles.
N95, N99, P100... Any hardware store would carry these.
I think most people learned that because of COVID, didn't they? N95s (worn properly) block 95% of pm2.5, which takes a danger level of 400 μg/m³ (well into the hazardous range) down to 20 μg/m³ (about half the cutoff for "unhealthy").
Yet only a handful of people locally were wearing N95s when the levels were that high, locally. People just don't care about their health, I guess? Not sure how else to interpret it.
