9/10: AIR QUALITY. Using Purple Air. Yes, the air quality is awful this morning - making the West Coast look like NOT the place to be!

When you use Purple Air to check outdoor air quality, here’s a few pointers I learned this morning to help accuracy: (1) uncheck the “inside air” box (unless you want to know about inside air), and (2) change the “conversion” option from “none” to “LRAPA” (this is Purple Air’s correction for over-reading of air quality affected by fire smoke). No matter what, though, it’s awful!
