I am in Spokane in eastern Washington. Last week we had a day of 50-60 mph winds and fires blew up across the state. Two tiny towns to the south, Malden (pop. 200) and Pine City (100) burned almost completely, with nearly every building burned. My wife and I drove through them today, it was awful.
We had about a week of unbreathable air, with air quality as bad as over 500. When it first began I bought a bunch of furnace filters and box fans and made some DIY air filters. I took one to an older colleague. They worked really well.
This was about our fourth smoke season in the last five years, and the worst one yet. When the stores have box fans and furnace filters back in stock I am going to get some more and keep them handy.
