There was a particularly nasty American west coast wildfire a couple years ago, skies red like a science fiction movie. Air purifiers were sold out everywhere, but you could still get a box fan and a couple furnace filters.

That wasn't my experience. The day the smoke moved in, I ran to the home store to grab a couple extra furnace filters, and there was a steady stream of people grabbing them, and heading to the box fan section. The secret seems to be out.

Yeah, the filters sold out everywhere here in Washington State in Sept 2020. My daughter was in Yellowstone at the time and, on her drive back, stopped at multiple home and hardware stores along the way and found none available.
