According to the Directorate of Air Pollution Control of KLHK, ISPU is a unitless number used to describe ambient air quality conditions at a certain location and is based on the impact on human health, aesthetic value, and other living things.

ISPU calculations are based on the measurement results of seven air pollutant parameters, namely PM10, PM2.5, NO2, SO2, CO, O3, and HC. Air pollutant parameter measurements are spread across 72 stations in various regions.

Based on Ministry of Environment and Forestry Regulation No. 14 of 2020 concerning the Air Pollution Standard Index, ISPU in the range of 0-50 indicates good air quality, the range of 51-100 means moderate air quality, and the range of 101-200 indicates unhealthy air quality that is harmful to humans, animals, and plants.

Furthermore, very unhealthy air quality in the range of 201-300 can increase health risks for sensitive groups. Meanwhile, hazardous air quality in the range of more than 300 can seriously harm health and requires quick handling.
