There are roughly 13,000 acres on fire within 20 miles of me (and about 10 million other people). Fortunately since I have asthma we already have 2 air purifiers that are running full blast.
Probably the scariest part of how toxic the air is right now is that it looks absolutely clear outside. Without checking the weather I would have never known it was that bad.
For AQI? I’m not totally sure honestly, I think it’s a combination of particulate matter readings, ozone, carbon monoxide, and a few other chemicals. I don’t know exactly what math is going on to turn that into a number rating, though. I just know “don’t breathe this” when the number is that high 😂
