Smart Air China is a small social enterprise that promotes DIY air purifiers as a low-cost solution to indoor particulate air pollution in China.
In January 2013, PhD student Thomas Talhelm wondered why air purifiers cost so much. He bought a HEPA filter on Taobao, strapped it to a simple fan, bought a particle counter, ran some tests, and published the results on a blog he called Particle Counting.
When people said they had trouble finding the right type of fan and a trustworthy HEPA, Thomas and his friends Gus and Anna decided to launch Smart Air in September 2013 to ship fans and the best HEPAs they could find to people all over China.
Smart Air believes that if more people saw our opensource data and testing, more people would know that clean air doesn’t have to cost thousands of dollars.
