AQI for Delhi

Good

AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.

Satisfactory

AQI: Satisfactory (51 - 100)
Air quality is considered satisfactory, and air pollution poses little or no risk.

Moderate

AQI: Moderate (101 - 200)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.

Poor

AQI: Poor for Sensitive Groups (201 - 300)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.

Very Poor

AQI: Very Poor (301 - 400)
Health alert: everyone may experience more serious health effects.

Severe

AQI: Severe (401 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.
