WHAT IS AQI
YOUR GUIDE TO AIR QUALITY LEVELS
The Air Quality Index (AQI) is a standardized scale used to measure how clean or polluted the air is and how it may affect your health. It converts complex air pollution data into a simple, easy-to-understand number that helps you quickly assess the air around you.
AQI considers major pollutants such as PM2.5, PM10, carbon monoxide (CO), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), and ozone (O₃). Each AQI value represents a specific level of health concern, ranging from Good to Hazardous.
By checking the AQI, you can make informed decisions—whether it's safe to go outside, exercise, or take precautions to protect your health. Higher AQI values indicate greater health risks, especially for children, the elderly, and people with respiratory conditions.
In short, AQI transforms complex air data into actionable insights, helping you stay aware, prepared, and protected—every day.
