According to the AQI index, a value of under 50 is considered to be best for human while Delhi is averaging out at more than 300 across the city. There are certain areas even worse affected such as Punjabi Bagh reading an average AQI of 999. This reading indicates that the AQI index cannot test the air as it has surpassed the maximum value on its scale.
