Methodology: Current pollutant concentrations are sampled from WeatherAPI for up to 400 large cities; US AQI values are calculated from PM2.5 using EPA breakpoints.

Why Are PM2.5 Levels So Low in These Cities?

The cleanest-air cities are usually those with light traffic and industry, plenty of wind and rain to clear the skies, and a coastal or high-latitude setting. Air quality shifts through the day, so a city near the top now may not stay there. This list samples live PM2.5 readings across hundreds of large cities and updates through the day.

We rank by PM2.5, the fine particles most relevant to health, so a low figure means genuinely clean air to breathe. Right now the cleanest air among the cities we track is in Antananarivo, with PM2.5 around 1.8 µg/m³.

Frequently Asked Questions: Cities With the Lowest PM2.5 Right Now

Which city has the cleanest air right now?
