Smog-eating air purifier for Beijing

Daan Roosegaarde, who has a design firm, Studio Roosegaarde, in Rotterdam, along with his partners, has designed a 23-foot Smog Free Tower – the world’s first outdoor air cleaner, The New York Times has reported. A powerful vacuum inside uses ionisation technology to suck up smog, filter out dangerous particles and release purified air, the report elaborated. Roosegaarde claims that in 36 hours, it can eliminate 70 to 80% of the impurities in the air from an area the size of a football stadium. He said that he plans to install the tower at a public location in Beijing this month to test its performance in the smoggy city, and cover four other Chinese cities over the next year.
