Standing between high-rises, the device is capable of cleaning between five million and 18 million cubic metres of air each day, depending on the weather, season, and level of pollution, according to a report by the Chinese website Thecover.cn.
A University of Chicago study found last year that air pollution in northern China had cut life expectancy by three years compared with the south of the country.
