3-Pollutant Multi-Matrix Model
AQHI 1 – 3Low Health Risk
Ideal air quality. Enjoy your usual outdoor activities. No special precautions required for general or at-risk populations.
AQHI 4 – 6Moderate Risk
At-Risk Individuals: Consider reducing or rescheduling strenuous activities outdoors if experiencing coughing or throat irritation.
AQHI 7 – 10High Risk
General Population: Reduce strenuous outdoor exertion. Children and seniors should avoid prolonged physical activity outdoors.
AQHI 10+Very High / Extreme
Severe Wildfire Event: Avoid outdoor physical exertion entirely. Remain indoors with certified HEPA filtration running.
