How the score works

We use the EPA annual summary of daily Air Quality Index values for each metro area (2025). Cities are ranked by the share of measured days rated good; metros with fewer than 300 measured days are left out. The table also shows days that were unhealthy at least for sensitive groups. Data checked October 18, 2026.

Want a list built around your own priorities? Take the six-question city quiz, or compare any two cities side by side. Sources are on how we get our numbers.
