Air Quality Health Impact Tool

Estimate how current air pollution conditions may affect daily activity and whether extra caution may be useful.

Use your local AQI if you know it.
Longer outdoor time can increase total exposure.
Harder breathing can increase inhaled pollution.
Sensitive groups may feel effects sooner.
Some masks reduce inhaled particles more than others.
Eye irritation, cough, chest tightness, or headache can matter.
How we calculate

We combine AQI, time outdoors, activity level, sensitivity, mask use, and symptoms into a simple impact score.
