Understanding the AQI
The AQI is divided into six categories:
"Good" AQI is 0 - 50. Air quality is considered satisfactory, and air pollution poses little or no risk.
"Moderate" AQI is 51 - 100. Air quality is acceptable; however, for some pollutants there may be a moderate health
concern for a very small number of people. For example, people who are unusually sensitive to ozone may
experience respiratory symptoms.
"Unhealthy for Sensitive Groups" AQI is 101 - 150. Although general public is not likely to be affected at this AQI
range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas
persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in
the air.
"Unhealthy" AQI is 151 - 200. Everyone may begin to experience some adverse health effects, and members of the
sensitive groups may experience more serious effects.
"Very Unhealthy" AQI is 201 - 300. This would trigger a health alert signifying that everyone may experience more
serious health effects.
"Hazardous" AQI higher than 300. This would trigger a health warning of emergency condition. The entire population
is then more likely to be affected.
