Understanding the Air Quality Index
EPA created its color-coded index to help people figure out how air quality can affect their health. Colors relate to levels of health concern, and numerical values reflect the department's data and meteorological conditions. For example, a value of 100 on the Air Quality Index corresponds to the federal standard for a pollutant, or the level EPA has set to protect public health.
On days with high readings on the Air Quality Index, protect yourself and your family.
- Limit your time outdoors, especially if you have asthma or other respiratory issues.
- Avoid prolonged or vigorous outdoor activity.
- Reschedule outdoor activities for another day.
- Keep your windows closed at home and in your vehicle to minimize exposure to ground-level ozone (smog).
- Avoid high-traffic areas, where the concentration of ozone — also known as smog — may be especially high.
- Understand the effects that air pollution can have on your health. Be proactive.
