The Air Quality Index (AQI) helps people understand how polluted the air is. As pollution increases, so does the AQI, raising health risks for vulnerable groups like children, the elderly, and those with breathing or heart issues. When the AQI is high, it’s advised to limit outdoor activities and consider using masks and air purifiers indoors.
The Air Quality Index (AQI) bands indicate air pollution levels, providing health advice based on how clean or polluted the air is.
