Air pollution needs no introduction in 2021. With Diwali behind us now, the bursting of crackers and the ongoing stubble burning in North India means entire cities from Delhi to Lucknow to Kanpur are now covered in layers of smoke, reducing visibility and the overall safe breathability of air in residential areas.

There are a number of Air Quality checking apps that you can use to know the status in your city. We’ll show you a few of these apps that you can use in your city. However, first, let us get a quick recap on how air quality is measured and what terms like AQI stand for.

How is Air quality measured?

Air quality is measured by taking into account a number of factors that come together on a uniform scale that helps citizens make sense of data. This unifying number is the AQI or Air Quality Index rating.

The AQI levels range from 0 to 500 degrees and shows changes in the amount of pollution in the air. The AQI number tracks five major air pollutants – Ground-level ozone, carbon monoxide, sulphur dioxide, Nitrogen dioxide, and airborne particles or aerosols such as PM2.5 and PM10.

AQI ratings can be measured in your area via services like or SAFAR India (System of Air Quality and Weather Forecasting And Research).

Understanding AQI levels

The lower the AQI rating of your region, the cleaner the air quality is. Here’s a quick chart for all rating ranges. Check out the chart below to know more.
