China has a found a novel way to tackle its massive air pollution problem: Putting up a giant air purifier the size of an industrial smokestack in the middle of a smog-plagued city.
Instead of pumping out billows of black smoke like the chimneys rising from factories in the northern province of Shaanxi, the 60m tall structure on the outskirts of the regional capital Xian blasts clean air.
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.
But a new study by the university in March found that China had made so much progress against smog that life expectancy could rise by more than two years.
