AirNow · 09/17/26

How we got this. Right now air is the EPA's Air Quality Index for each city's reporting area, from AirNow's public feed, refreshed every hour. Cities rank from cleanest to dirtiest at this moment. There's no state list here, since a whole state's current air isn't one honest number and we won't invent one. It refreshes every hour.

Rankings by The Honest Local from public data, one page per list, refreshed on each source’s own cycle. Places with no reading are left out rather than estimated. Every value on this page carries its source in the page’s structured data.
