AQI values at and below 100 are generally considered to be satisfactory. When AQI values are above 100, air quality is considered to be unhealthy, at first for members of populations at greatest risk of a health effect, then for the entire population as AQI values get higher (greater than 150).

Air Quality Index. The Air Quality Index, or AQI, much like an air quality “thermometer”, translates daily air pollution concentrations into a number on a scale between 0 and 500. The numbers in this scale are divided into six color-coded ranges, with numbers 0-300 as seen below.

What is healthy air quality index?

The Air Quality Health Index or (AQHI) is a scale designed to help understand the impact of air quality on health. It is a health protection tool used to make decisions to reduce short-term exposure to air pollution by adjusting activity levels during increased levels of air pollution.

What does ‘unhealthy air quality’ mean?

Unhealthy (Red): 151-200 AQI is considered unsafe and anyone could experience negative health effects from pollution in the air. Very Unhealthy (Purple): 201-300 AQI is a serious health risk level for everyone and you may see a health alert on your phone or weather app.
