What Does the Air Quality Index (AQI) Mean?
The AQI scale runs from 0 to 500, indicating how clean or polluted the air is:
- 0-50 (Good) – Clean, fresh air for outdoor activities
- 51-100 (Moderate) – Acceptable for most, but sensitive individuals may feel effects
- 101-150 (Unhealthy for Sensitive Groups) – Children, elderly, and those with respiratory issues should limit exposure
- 151-200 (Unhealthy) – Everyone may experience health effects; limit outdoor activities
- 201-300 (Very Unhealthy) – Health warnings issued; outdoor exposure should be minimized
- 301-500 (Hazardous) – Emergency conditions; everyone should stay indoors
