Those apps and sites that pretend to tell you what the air quality is like in your area--well around here they're usually wrong. If they say the air is GOOD...it's really, really bad. Right now it's toxic outside, here.Yellow, unbreathable. But they say...GOOD! Compared to what? The planet Neptune?

The sensor is $229 (plus an outdoor power supply). https://www2.purpleair.com/products/purpleair-pa-ii
