AQI India: Real-Time Air Quality Index (AQI) | Air Pollution Level
about banner


The AQI (air quality index) refers to an index that reports on the quality of air daily. It informs people of how polluted or clean the air is, as well as how the air quality impacts the health. The AQI spotlights the impacts on health after a certain time of having breathed in polluted air. Usually the AQI is measured for 5 major air pollutants, nitrogen dioxide, sulfur dioxide, carbon monoxide, particle pollution and ground-level ozone.

The AQI can be thought of as a measure going from 0 to 500. A higher AQI value indicates a higher air pollution level, and a greater concern for public health. To give an example, a value of 50 on the AQI means that the quality of air is good, impacting public health very little, whereas a value of 300 on the AQI means that the air quality is hazardous. A value of 100 on the AQI is thought of, generally speaking, as satisfactory. Greater than 100, and the air quality starts impacting the public health. AQI Numbers in India are comparitively very high when compared to other developed countries.

The air quality in your location has an impact on how you breathe and therefore live. Air quality is like weather; it changes from time to time. Once you understand AQI, you take measures reducing being exposed to air that is unhealthy. For instance, you can spend less time on at outdoor activity on a day when the AQI is poor. Or you can perform an activity that requires less exertion, like walking instead of running.

AQI values are usually below 100. AQI values of 200 are infrequent, and 300, extremely rare. They vary according to the season as well as the time of day. The major constituents of air pollution in India are nitrogen oxides, Sulphur dioxide, particulate matter (suspended particulate matter and respirable suspended particulate matter), carbon monoxide, photochemical oxidants, organic in ambient air and trace metals in ambient air.
