The purpose of the AQI is to help you understand what local air quality means to your health. To make it easier to understand, the AQI is divided into six categories:

Category
AQI
Color Code
Health Statements
Good
1 - 50
Green
No health impacts are expected when air quality is in this range.
Moderate
51-100
Yellow
Unusually sensitive people should consider limiting prolonged outdoor exertion.
Unhealthy for Sensitive Groups
101-150
Orange
Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
Unhealthy

Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion.
