AirNow is experiencing intermittent technical issues with the location lookup function on its main page at https://www.airnow.gov and in the AirNow app. We are working to resolve the issue. In the meantime, you can visit the AirNow Interactive Map to see your current air quality and forecast.
EPA has updated the Air Quality Index (AQI) for particle pollution, at the same time the Agency updated the annual health-based standard for this harmful pollutant. AirNow will reflect the updates when they become effective -- 60 days after the rule is published in the Federal Register. Read about the AQI updates.
EPA will host the National Air Quality Conference (NAQC) as a virtual only event on March 18-21, 2024.
