Air Now

Air Now is a government-supported website and tool that provides real-time air quality information for locations across the United States. It helps people understand current levels of air pollution, such as ozone and particulate matter, which can affect health. By offering easy-to-understand color-coded air quality indices, forecasts, and health advisories, Air Now enables individuals and communities to make informed decisions—like limiting outdoor activities during high pollution days—to protect well-being, especially for sensitive groups like children, the elderly, and people with respiratory conditions.
