Los Angeles Pollen Forecast & Air Quality Report

The Air Quality Index (AQI) is a standardized tool used by environmental agencies to report daily air quality and its impact on health. It runs on a scale from 0 to 500 - lower values mean cleaner air, while higher values indicate more polluted air and greater health risks (for example, an AQI of 50 or below is "Good," whereas over 300 is "Hazardous").
