Tracking air quality

The Wynd tracker measures the amount of particulate matter (PM) in the air. PM includes things such as dust, allergens, industrial pollution, and more. The tracker uses this measurement to calculate the air quality index (AQI). The tracker’s light color indicates the AQI.

Here's what the Wynd tracker's light colors mean:

AQI: 0-50
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: 51-100
Air quality is acceptable: however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: 101-150
Unhealthy for sensitive groups
Members of sensitive groups may experience health effects. The general public is not likely to be affected.
AQI: 151-200
Everyone may begin to experience health effects, members of sensitive groups may experience more serious health effects.
AQI: 201-300
Very unhealthy
Health alert: everyone may experience more serious health effects.
AQI: 301-500
Health warnings of emergency conditions. The entire population is more likely to be affected.

We use the EPA standard algorithm to convert particulate matter to AQI. Read more about particulate matter here.
