A comparison would be nice. The smoke can be awful, no doubt - but is it worse for a person's health than living near a busy road or highway? That is 24x7, and cumulative over many years.
I moved across town two years ago, into an expensive house (it's not a nice house, just an expensive house) that's directly adjacent to a road with lots of traffic, and I think every day about air quality now.
I also started riding a motor scooter around Denver (and across the country to British Columbia, then to Seattle, and back) and I wonder about protecting myself from road pollution while riding, especially in rush hour in cities.
I wonder if an n95 would improve things for me, and I wonder how much damage I'm doing to myself by breathing vehicle pollution (emissions, brake dust, tire rubber micro-plastics), eg: https://www.theguardian.com/environment/2022/jun/03/car-tyre...
I'm 33, I'm already resigned to not-great long-term health outcomes based on environmental contaminants in food and the air.
I avoid most meat (that gets me out of the factory farmed meat harm universe) and avoid most processed food, and am generally "healthy and active", but I despair of the world, for many reasons.
Ugggghhhhhhhh.
Unscientific, but it'll tell you a bit.
Much of emissions may not be caught, but those are relatively "clean" now, brake dust and tire rubber falls to the ground relatively quickly (unless it's being kicked back up by the vehicles).
You can get various air quality meters, too.
Here's a different SF map showing where most of the exhaust is (PDF): https://www.sfdph.org/dph/files/ehsdocs/airquality/airpollut...
Or, to stay in the same realm as wildfire smoke, living in a place where lots of wood stoves without filter? According to numbers I once saw seen in 'typical' small villages with no heavy industry, pollution from that is the biggest contributer, more than traffic and farming combined. Not 24x7 though.
My Dyson Purifier never reported anything though.
