What does AQI mean?
AQI (Air Quality Index) is an index of how healthy the air is. It is usually based on PM2.5 particles. High values mean poorer air quality. Values above 100 are unhealthy for sensitive groups, while values above 150 can be dangerous for everyone.
| AQI value | Health advice |
| 0–33 | Very good – Enjoy outdoor activities |
| 34–66 | Good – Enjoy outdoor activities |
| 67–99 | Moderate – Avoid strenuous activities if you are sensitive |
| 100–149 | Unhealthy for sensitive groups – Reduce outdoor activities |
| 150–200 | Unhealthy – Everyone should reduce outdoor exertion |
| 200+ | Dangerous – Avoid outdoor physical activity |
