✍️ Wildfire smoke from Canada has drifted into the US, prompting air quality alerts, and officials explain the Air Quality Index (AQI) and its categories.
--
👉 The Air Quality Index is a federal measurement system that categorizes air pollution levels
👉 The index uses six color-coated categories: good, moderate, unhealthy for sensitive groups, unhealthy, very unhealthy, and hazardous
👉 The categories range from 'good' to 'hazardous', with each level posing a different health risk
👉 The public can check the AQI near them on AirNow.gov
