People visit the interior of a 60-meter-tall air purification tower, the world's biggest air purifier, to combat smog and other air pollution in Xi'an city, northwest China's Shaanxi province, 17 April 2018. Testing has shown that 60-meter-tall air purification tower in Xi'an, capital of northwest China's Shaanxi Province, can cut the average PM2.5 density by 15 percent over an area of 10 square kilometers. Researchers released the test results of the tower's purification capability at a press conference on Tuesday (17 April 2018). On severely polluted days, the tower can purify five million cubic meters of polluted air on a daily basis, according to Cao Junji, researcher with Institute of Earth Environment under the Chinese Academy of Sciences.
