Bangor, Maine Emerges as America's Clean-Air Outlier
Bangor, Maine is the only U.S. city on all three American Lung Association clean-air lists, with zero days of unhealthy ozone and short-term particle pollution and among the lowest year-round particle levels, thanks to its forests, small population, and distance from major polluters. By contrast, Los Angeles has the worst ozone and Bakersfield the worst year-round particle pollution. The findings rely on EPA data from 2022–2024 and come amid concerns about climate change and regulatory rollbacks, while Bangor’s clean air is used as a selling point to attract residents seeking healthier living.
