Cities Tracked
Coverage across every US city, county, and ZIP code — from major metros to small towns — all powered by real-time EPA monitoring station data.
Historical Data
EPA annual AQI data from 2016–2025 lets you see long-term air quality trends, seasonal patterns, and year-over-year improvements or declines.
Comprehensive Tracking
Track PM2.5, PM10, Ozone, Carbon Monoxide, Nitrogen Dioxide, and Sulfur Dioxide — the six pollutants the EPA uses to calculate the Air Quality Index.
Why Air Quality Matters
Air pollution is one of the leading environmental health risks in the United States. Fine particles and ground-level ozone can irritate the lungs, worsen asthma and heart conditions, and reduce life expectancy. Checking the AQI before outdoor exercise, opening windows, or planning travel helps you make smarter decisions for your health every day. LocalAirData sources live AQI from the EPA's AirNow network and historical trends from the EPA's Air Quality System (AQS) — the same data used for federal regulatory reporting.
