AQI 101–150: Unhealthy for Sensitive Groups
Sensitive individuals, such as those with asthma or other respiratory issues, may begin to experience health effects, although the general population is unlikely to be affected. It is advised that active children, adults, and those with respiratory conditions limit extended outdoor exertion.

Health effects may begin to affect everyone, with sensitive groups potentially experiencing more serious symptoms. Active children and adults, and people with respiratory illnesses should avoid prolonged outdoor activity, while others—especially children—should reduce outdoor exertion.

This range signals emergency-level health warnings. The entire population is more likely to experience adverse health effects. Those with respiratory conditions and active individuals should avoid all outdoor activity, while everyone else, particularly children, should limit time spent outdoors.
AQI 300+: Hazardous
Air quality is extremely poor, posing a serious risk to health for everyone. A health alert is in effect, and all outdoor exertion should be avoided by the entire population.
