When artist Daan Roosegaarde visited Beijing in 2014, he was inspired by what he didn’t see.From his hotel room on the 32nd floor, his view of the sprawling Chinese capital was totally obscured by smog. “It was all gone,” Roosegaarde says. “The city was completely covered with smog.”
Two years later, he is taking the world’s largest air purifier on a tour of China. The Smog Free Tower will create bubbles of clean air in inner-city parks and, Roosegaarde hopes, raise awareness of the dangers of air pollution.
