The air we breathe is not as clean as it once was – and in many cases, it is getting worse. According to a recent study by researchers at UC Berkeley, smog kills about 4,000 people every day in China . And in the US about 4 in 10 people live in counties that have unhealthy levels of either ozone or particle pollution, according to the American Lung Association . To help clean up our air and make it breathable again, Dutch designer Daan Roosegaarde created a 23-foot (7-metre) tall air purifier called the Smog Free Tower. The tower-like device essentially sucks up smog like a vacuum from the top and then releases the filtered air through its six-sided vents. It can clean more than 30,000 cubic metres of air per hour and runs on 1,400 watts of green energy. The project, which was funded on Kickstarter , took Roosegaarde about three years of research and development, but he is finally showing off the prototype of his giant air purifier this week in Rotterdam.
