Frequently Asked Questions

What does a "Good" AQI rating mean?

A Good AQI (0-50) means air quality is satisfactory and poses little or no health risk. You can freely enjoy outdoor activities including exercise, sports, and recreation without air quality concerns.

Is it safe to exercise outdoors when AQI is Good?

What cities consistently have Good air quality?

Cities like Honolulu, Burlington (VT), and many smaller cities in the Pacific Northwest and northern New England regularly achieve Good AQI ratings. Coastal cities with strong winds tend to have the cleanest air.

How is Good AQI measured?

AQI is calculated from ground-level ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulfur dioxide, and nitrogen dioxide measurements. Good AQI means all measured pollutants are well below EPA health standards.

Can AQI be Good in a big city?

Yes, many large cities achieve Good AQI days, especially after rain or during windy conditions. Cities with strong environmental regulations and low industrial activity can maintain Good air quality much of the year.
