Cities with the cleanest air quality in Bhutan

Air pollution is one of the most documented environmental health risks of our time. Fine particles (PM2.5), nitrogen dioxide (NO2), and ground-level ozone affect respiratory health, cardiovascular function, and sleep quality - often without visible signs. Choosing where you live, work, or spend extended time matters more than most people realise.

ClearSpot aggregates air quality data from official open government monitoring networks and the Copernicus Atmosphere Monitoring Service (CAMS) into a normalised score for every scored city. The ranking below reflects monthly averages at default sensitivity thresholds. Cities at the top have consistently lower modelled air pressure - not just on one good day.

The 26 cleanest cities for air quality in Bhutan in May 2026 are listed below, scored from 0% (maximum pressure) to 100% (no documented pressure within default thresholds). Click any city to explore the full environmental breakdown and compare with nearby places.
