Beijing residents concerned about breathing the capital's thick gray air are adapting, inventing and even creating businesses to protect the health of their families and others. Boquillod's start-up, AirVisual, also provides air pollution readings around the world using data from more than 10,000 monitoring sources, both public and private. The company shares a 3-D real-time global map of air pollution and weather patterns on its website. He consults with schools, hospitals and offices to test air quality and find gaps in door and window frames that could allow pollution in. Some international schools in Beijing have installed air-inflated sports domes for athletics, complete with air filters and rotating doors to help keep them sealed.
