Air Quality Index Updates Across the U.S.
US · Published Oct 14, 2026
• The AirNow system provides real-time updates on air quality across the United States, reporting the Air Quality Index (AQI) values for ozone and particle pollution.
• The AQI scale ranges from 'Good' (0-50) to 'Hazardous' (301+), with categories such as 'Moderate,' 'Unhealthy for Sensitive Groups,' 'Unhealthy,' and 'Very Unhealthy' in between.

Impact & Risks

Air quality impacts vary depending on the AQI level. Sensitive groups, including children, the elderly, and individuals with respiratory or heart conditions, may experience health effects when AQI values exceed 100 ('Unhealthy for Sensitive Groups'). At higher levels, such as 'Unhealthy' (151-200) or 'Very Unhealthy' (201-300), the general population may also experience adverse health effects. Hazardous levels (301+) pose serious risks to everyone, potentially leading to respiratory distress or other severe health issues. Monitoring AQI values is crucial for minimizing exposure to harmful pollutants.
