The data of this App comes from the live feed of US Embassy.

What is the Beijing air pollution index and what does it measure?

This is a live feed of air quality measurements from a monitoring station in the US embassy in downtown Beijing. The station measures PM2.5 particles. This means particles that are smaller than 2.5 microns in size, like soot from diesel engines. Research shows that these are the most dangerous pollutants. The first part is the date and time. Then comes the measurement, then an index that is calculated from the measurement, then a health impact rating. Anything below 100 is good, anything above 100 is a cause for concern. The feed shows the four most recent measurements in rotation (they are generally hourly), and today's average.

Customer Reviews

Great, uses US data. Needs notifications

The app does what it says and uses reliable numbers from the U.S. embassy. I really wish it could notify you when PM2.5 gets above a certain level!

A must app if you live in Beijing

Readings taken from us embassy! Not xxx false and misleading from other china apps. If you have kids and conscious about their health is a must app.

Great app

Living in Pudong / Shanghai this app is a must. True values are helpful before you plan outside activities. May sound funny but the filter masks may need to be considered for jogging and biking.
