Important information about the accuracy and limitations of air quality data on this Site.
AQI of My Location uses air quality estimates from the Open-Meteo Atmospheric Model, which blends satellite observations, reanalysis data, and numerical weather prediction outputs. While this data is generally reliable for trend analysis and broad health guidance, it may differ from ground-based monitoring stations operated by official government agencies.
For regulatory compliance or official air quality reporting, always refer to your national or regional environmental protection agency. In the United States, this is the EPA’s AirNow (airnow.gov). In India, refer to CPCB Sameer App or state pollution control board data.
The health recommendations on this Site are based on US EPA AQI categories and publicly available research. They are intended as general guidance and do not account for individual health conditions, age, fitness level, or local factors not captured in the data.
If you have asthma, COPD, cardiovascular disease, or other respiratory or cardiac conditions, please consult your physician before using AQI data to make outdoor activity decisions.
The cigarette equivalent calculation is an educational approximation based on Berkeley Lab research. It is intended to make PM2.5 risk relatable to a general audience. It does not imply that breathing polluted air and smoking cigarettes carry identical health risks, as cigarette smoke contains additional compounds (nicotine, carbon monoxide, carcinogens) not present in ambient air pollution.
