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.
