Hyper-local, Real-time Air Quality Map

PurpleAir map

The air we breathe has direct consequences on our health. According to The National Oceanic and Atmospheric Administration (NOAA), "Poor air quality is responsible for an estimated more than 100,000 premature deaths in the United States each year. Costs from air pollution-related illness are estimated at $150 billion per year". PurpleAir has designed a hyper-local, real-time air quality map that targets the need to measure and visualize the air quality around us.

How does it work?

Every icon on the PurpleAir map represents a public PurpleAir sensor, and the color indicates the real-time PM2.5 reading on the US EPA Air Quality Index scale. The sensors with no outline are registered as outdoor sensors, and the sensors with black rings are registered as indoor sensors.

When clicking a sensor icon, two informative boxes display. One shows the sensor information and averages over the last week. The other shows a graphical chart of Channels A and B readings over the last week.
