Frequently Asked Questions

What is the Air Quality Index (AQI)?

The Air Quality Index (AQI) is a measure used to communicate how polluted the air currently is or how polluted it is forecast to become. The AQI focuses on health effects you may experience within a few hours or days after breathing polluted air.

How often is the AQI data updated?

Our AQI data is updated in real-time, with readings typically refreshed every hour from our monitoring stations across India.

What do the different AQI categories mean?

The AQI is divided into six categories: Good (0-50), Moderate (51-100), Unhealthy for Sensitive Groups (101-150), Unhealthy (151-200), Very Unhealthy (201-300), and Hazardous (301+). Each category corresponds to different levels of health concern.

How can I protect myself when the AQI is high?

When AQI levels are high, you can protect yourself by staying indoors, using air purifiers, wearing masks when outdoors, and avoiding strenuous outdoor activities.
