Air Quality Protect Yourself and Family
EPA’s Air Quality Index, or AQI, is a tool to help you quickly learn when air pollution is likely to reach unhealthy levels. Local TV stations, radio programs, and newspapers carry these air quality forecasts to tell you when particle levels are likely to be unhealthy. You can use the AQI to plan your daily activities to reduce exposure to air contaminants.
Your exposure to air contaminants depends mainly on where you live and work and how much time you spend outside. When ozone and/or particle pollution levels are high, you can:
- reduce the amount of time you spend outside;
- plan outdoor activities when ozone levels are lower, usually in the morning and evening;
- do easier outdoor activities, such as walking instead of running; and
- plan indoor activities.
