AIR QUALITY


The Air Quality table shows the 17-year average of the EPA's Air Quality Index, an approximate indicator of overall air pollution. The index is based on measurements of carbon monoxide, ozone and other pollutants.

The % Good Days column is the percentage of days measured in your favorite retirement city or town that offered good air quality with the lowest level of pollutants.

Vail, Colorado and Kailua, Hawaii boast the best air quality among our 99 top retirement cities with a greater than 93% of Good Days.
