No. There is no alternative, I don't drive a car. When I'm out of supplies, time to shop! Low air quality is no longer my fault.
OTOH I don't have asthma. I do carry a 3m M95 mask if smoke gets too bad. Which I wear in stores, these days.
You would be shocked by what I spit up after shifts fighting chip fryer or bake oven fires. City fire department would come, but stand there and watch us maintenance men work. Shoveling out burning chips onto concrete floor & spraying water on them, mostly. Lungs & trachia are lined with cilia, and if you're not a smoker, they do their job pushing out bad particles.
Remember native Americans used to burn the prairies to keep down the weeds & tree saplings. Kansas ranchers still do. It's a tradition still be be adopted by California.
