I starting wearing N95 masks years before Covid-19 reared up. The air being under AQI100 is a rarity where I live and +400 not unheard of.

Those are some rough numbers, is it from industrial impact something else?

The really high numbers are from semiannual ag burning while the steady high number is from the geographic location in a valley that seems to trap most automotive exhaust.
