The Air Quality Index (AQI) runs from 0 to 500 and is divided into six levels of health concern. While some groups face higher risk, poor air quality affects everyone. No one is immune to the health effects of wildfire smoke.

0–50 (Good): Air quality is satisfactory with little to no risk.
51–100 (Moderate): Acceptable for most. Those unusually sensitive may experience minor concerns.
101–150 (Unhealthy for Sensitive Groups): Children, older adults, and individuals with respiratory or cardiac conditions should exercise additional caution.
151–200 (Unhealthy): Everyone may begin to experience health effects. All New Yorkers should take precautions.
201–300 (Very Unhealthy): Health alert. All New Yorkers may experience serious health effects.
301+ (Hazardous): Emergency conditions. The entire population is likely to be affected.
