I fled the 2018 Camp Fire for a few months and returned to the Chico metro area only to have to move again because of combination of increasing insurance rates, unreliable electricity thanks to PG&E "PSPSes", and recurrent smoke from additional nearby forest fires. The AQI was 500-1000 for weeks at a time. Now after moving around the 100th meridian west far from forested areas, I have a BlueAir 680i churning away constantly and 4 large HVAC intake registers with high but sensible MERV rating filters to keep indoor air quality roughly 0 PM1/PM2.5/PM10 as per multiple types of AQMs with different grades of sensors. Absolutely no problem with allergies, until I go outside. :D Ozone is one thing I do worry about, but it's less where I live now, but GAC filter media keeps it in check.
