Health & Scientific Resources
→ How to read US EPA Air Quality Index before going outside → Understanding Air Quality Index levels and what they mean → When haze forms and what it does to air qualityHow is this AQI calculated?
The primary Air Quality Index (AQI) shown above is calculated using the US EPA Linear Interpolation formula based on PM2.5 concentration (Fine Particulate Matter).
- Current PM2.5: 13.8 µg/m³
- Calculation: Your city falls into the "Good" category (Category 1).
Note: While several pollutants (O3, NO2, SO2) are monitored, PM2.5 is used as the primary "driver" for the main index value as it typically represents the highest health risk.
