There are six AQI categories, namely Good + Satisfactory, Moderately Polluted, Poor, Very Poor, and Severe.

Each of these categories is decided based on the ambient concentration values of air pollutants and their likely health impacts (known as health breakpoints). According to the AQI scale, the air quality check between 0 and 50 is "good", 51 and 100 "satisfactory", 101 and 200 "moderate", 201 and 300 "poor", 301 and 400 "very poor", and 401 and 450 "severe".
