Frequently Asked Questions

What US city has the best air quality? ▼

Cities in the Pacific Northwest and rural areas often rank highest for air quality. However, air quality varies significantly by season and specific neighborhood. Our rankings use annual average AQI data from EPA monitoring stations.

What is a good AQI for a city? ▼

An AQI of 0-50 is rated "Good" by the EPA and represents the cleanest air. An AQI of 51-100 is "Moderate." Above 100 is considered unhealthy for sensitive groups. Most ZIP codes in our top rankings have AQI scores below 40.

Where should I live if I have asthma or allergies? ▼

Look for ZIP codes with AQI scores below 40, low PM2.5 levels, and few Unhealthy Days per year. Our Air Quality section on each ZIP code profile shows all these metrics.
