China Built The World’s Biggest Air Purifying Tower And It …

Product Details: The world’s largest air purifier is an experimental tower located in Xian, Shaanxi province, northern China. It stands over 100 meters (328 feet) high and is designed to tackle China’s chronic smog problem. The tower uses greenhouses and specially coated solar panels to operate year-round, even in winter when pollution is heaviest due to coal heating. The system sucks in polluted air, heats it with solar energy, and then passes it through multiple layers of cleaning filters. The tower produces over 10 million cubic meters (353 million cubic feet) of clean air daily and has improved air quality over an

area of 10 square kilometers (3.86 square miles). It requires minimal power input during daylight hours and is monitored by a dozen pollution monitoring stations.
