AIR QUALITY


The Air Quality table shows the 14-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.
