AirNow Announcements

3/26/19 - To help you get ready for fire season there are two new Wildfire Guide factsheets available: Protect Your Pets from Wildfire Smoke (PDF), and Protect Your Large Animals and Livestock from Wildfire Smoke (PDF).

AirNow status during the federal government shutdown: AirNow will continue to provide the public with current and forecast air quality information during the federal government shutdown; however EPA will not post additional information to the site during that time.

In the event of an environmental emergency imminently threatening the safety of human life, or where necessary to protect certain property, the website will be updated with appropriate information.
To increase our capacity to provide air quality information in light of high demand, EPA is reviving our pre-September 2018 version of AirNow to supplement our redesigned website
Redesigned Coming Soon
Finding your air quality will be a snap on our new mobile friendly site. Simply enter your ZIP code, city, or state and a dial will display your local conditions. You will also be able to locate air quality monitors near you with our interactive map. Preview the new dial (PDF)
