Buildings that purify the outside air come to New York City

Beijing and other cities already have buildings that are designed with technologies that clean the air of the cities they are located in. With its facade covered in the spray-on solution Pureti, the new NYC building at 570 Broome Street in Soho is breaking down contaminants in Manhattan air. It utilizes a photocatalytic process that transforms polluting particles into oxidizing agents. This treatment is said to offer the purifying power of 500 trees; the equivalent of taking 2,000 cars off the road for a year.
