An experimental tower over 100 meters (328 feet) high, built in Xian in Shaanxi province (northern part of China), is now the World’s Largest Air Purifier, bringing noticeable improvement to the air quality in that part of China, according to the scientists leading the project. It is being tested by researchers at the Institute of Earth Environment at the Chinese Academy of Sciences. Cao Junji, head of the research, said improvements in air quality had been observed over an area of 10 square kilometers (3.86 square miles) in the city over the past few months and the tower has managed to produce more than 10 million cubic meters (353 million cubic feet) of clean air a day since its launch. Cao added that on severely polluted days the tower was able to reduce smog close to moderate levels. The system works through greenhouses covering about half the size of a soccer field around the base of the tower. Polluted air is sucked into the glasshouses and heated up by solar energy. The hot air then rises through the tower and passes through multiple layers of cleaning filters. It is definitely the biggest air filter on planet earth, at the moment. Its presence is desperately needed because Xian experiences heavy pollution in winters, due to much of the city’s heating source being dependent on coal.
