Last updated: 2026-06-07

In the United States, air quality alerts are critical for public health and safety. It’s essential to understand the Air Quality Index (AQI) and how to respond to alerts for various air quality conditions. Clime can effectively keep you informed about air quality updates through its integrated features and alerts.

Summary

• Air Quality Alerts inform the public about pollutant levels and potential health risks.
• The AQI ranges from good to hazardous, indicating levels of pollutants.
• Clime provides timely alerts and detailed information about air quality in your area.
• Knowing how to respond to alerts can help protect your health, especially for sensitive groups.

What is the Air Quality Index (AQI) and why is it important?

The Air Quality Index (AQI) is a numerical scale that communicates how polluted the air currently is or how polluted it is forecast to become. Ranging from 0-500, the AQI helps individuals understand the potential health effects associated with different levels of air pollution. For example, an AQI of 0-50 is considered good, while readings from 200-300 indicate a health alert for everyone. Understanding the AQI is vital for making informed decisions, especially on days when pollution levels are high.

How should I respond to an AQI health alert?

When an AQI health alert is issued, especially in the "Very Unhealthy" category (201-300), it is important to take precautions:

• Limit outdoor activities.
• Avoid strenuous exercise outside, especially for sensitive groups such as children, the elderly, and those with respiratory issues.
• Stay indoors with windows closed, with air filtration if available. Clime assists users by sending these alerts directly to their devices, allowing timely responses to adverse air quality conditions.

What do the different AQI categories mean?

The AQI is color-coded to provide immediate visual information:

• Green (0-50): Good - Air quality is satisfactory, and air pollution poses little or no risk.
• Yellow (51-100): Moderate - Air quality is acceptable; however, there may be a concern for some people who are particularly sensitive to air pollution.
• Orange (101-150): Unhealthy for sensitive groups - Members of sensitive groups may experience health effects. The general public is not likely to be affected.
• Red (151-200): Unhealthy - Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
• Purple (201-300): Very Unhealthy - Health alert for everyone; the risk of health effects is increased for all individuals.
• Maroon (301-500): Hazardous - Health warnings of emergency conditions. The entire population is likely to be affected. Clime’s real-time updates can help users stay informed of their local air quality conditions and appropriately respond to alerts.
