Something I did not know about filters and wildfires: "When this mess is all done, make sure you change your AC filter. Many filters rely on electrostatic charge, and because wildfire smoke is charged, it can reduce the filter’s effectiveness significantly because it ‘depletes’ the charge." I've been through the smoke/heatwave combo (haven't we all by now?), and I have nothing but sympathy. #wildfires #smoke #airquality https://yourlocalepidemiologist.substack.com/p/bad-air-bad-lettuce
