Understanding the U.S. Air Quality Index
The U.S. Air Quality Index (AQI) is the Environmental Protection Agency’s tool for reporting outdoor air quality and health. The AQI is a crucial indicator of the level of air pollution in a given area and is used to inform the public about potential health risks associated with air quality.
How the AQI Works
The AQI includes six color-coded categories, each corresponding to a range of index values. A higher AQI value indicates a greater level of air pollution and a greater health concern. The six categories are designed to provide a clear and easy-to-understand indication of air quality, allowing individuals to take necessary precautions to protect their health.

AQI Categories and Health Concerns
AQI values at or below 100 are generally thought of as satisfactory. AQI values above 100 are considered unhealthy, first for certain sensitive groups of people, then for everyone as AQI values increase. The AQI categories and corresponding health concerns are as follows:
AQI values between 0-50 are considered good, with little to no health risk. AQI values between 51-100 are considered moderate, with some health concerns for sensitive groups. AQI values between 101-150 are considered unhealthy for sensitive groups, while AQI values between 151-200 are considered unhealthy for everyone. AQI values above 200 are considered very unhealthy, with significant health concerns for the entire population.
How to Check the Air Quality Index
The AQI is available in many locations inside Apple Maps and Google Maps on mobile devices. In addition, the Environmental Protection Agency’s AirNow.gov website provides continually updated AQI information. This allows individuals to easily access current air quality conditions and make informed decisions about their outdoor activities.
To check the AQI in your area, simply open Apple Maps or Google Maps on your mobile device and search for “air quality” along with your location. You can also visit the AirNow.gov website and enter your ZIP code or city and state to access current AQI information.

Why Checking the AQI is Important
Checking the AQI is important because it allows individuals to take necessary precautions to protect their health. When AQI values are high, it’s essential to limit outdoor activities, especially for sensitive groups such as children, older adults, and people with respiratory conditions. By staying informed about current air quality conditions, individuals can reduce their exposure to air pollution and minimize potential health risks.
What You Can Do to Reduce Air Pollution
While the AQI is an important tool for reporting air quality, it’s also essential to take steps to reduce air pollution in your community. Some ways to reduce air pollution include:
Using public transportation, carpooling, or driving electric or hybrid vehicles; reducing energy consumption by turning off lights and electronics when not in use; recycling and composting to reduce waste; and supporting policies and initiatives that promote clean air and reduce pollution.
Conclusion
In conclusion, the U.S. Air Quality Index is a vital tool for reporting outdoor air quality and health. By understanding the AQI categories and corresponding health concerns, individuals can take necessary precautions to protect their health. Checking the AQI is easy and convenient, and by taking steps to reduce air pollution, we can all contribute to cleaner, healthier air for everyone.
Frequently Asked Questions
Here are some frequently asked questions about the AQI:
Q: What does the AQI measure?
A: The AQI measures the level of air pollution in a given area, including pollutants such as particulate matter, ozone, nitrogen dioxide, and sulfur dioxide.
Q: How often is the AQI updated?
A: The AQI is updated continually, with new data available every hour.
Q: What are the health risks associated with high AQI values?
A: High AQI values are associated with a range of health risks, including respiratory problems, cardiovascular disease, and even premature death.
Q: Can I check the AQI on my mobile device?
A: Yes, the AQI is available on Apple Maps and Google Maps on mobile devices, as well as on the AirNow.gov website.
Q: How can I reduce my exposure to air pollution?
A: You can reduce your exposure to air pollution by limiting outdoor activities when AQI values are high, wearing a mask, and taking steps to reduce air pollution in your community, such as using public transportation and reducing energy consumption.
