![]() ![]() Based on filter type, HEPA + activated carbon dominated the market with share of 53.10. And preliminary research shows the tower which some are calling the world’s largest air purifier has cut air pollution significantly across a broad swath of the surrounding area. Last year a 4-meter-high filter called “CityTree” was tried out in Berlin. China air purifier market can be segregated based on filter type, end use, distribution channel, and region. Circa 2018 It may look like just another giant smokestack, but a 200-foot tower in the central Chinese city of Xi’an was built to pull deadly pollutants from the air rather than add more. The idea has worked very well in the test run.”Ĭao and his team are now planning a 500-meter-tall and 200-meter-wide tower, with greenhouses covering 30 square kilometers that would be able to purify air for a small city.Īir purifiers have been installed in China before, but only in a symbolic way. Cao Junji, head of research, said, “It barely requires any power input throughout daylight hours. The greenhouses are powered by solar energy and are able to run in winter as well as summer. The expelled air contains 15 percent less particulate matter than it did before being scrubbed. The smog is heated in the greenhouse by solar energy, then rises through the tower, passing through several layers of cleaning filters. A skyscraper-sized air purifier was built in Xi'an to clear the air. The tower sucks in polluted air and funnels it into greenhouses at the base of the structure. 4 Figure 5: The Ground Water Quality in China Source. The tower, which is being tested by researchers from the Institute of Earth Environment at the Chinese Academy of Sciences, has noticeably cleaner air over an area of 10 square kilometers since being turned on last year, according to the South China Morning Post. A 100-meter-tall experimental air purifier has been built in Xi’an, the capital of China’s central Shaanxi province, reported The Inhabitat. An experimental 100-meter-high tower has been built in Xi'an City, northwest China's Shaanxi Province, in a bid to boost the fight against. ![]()
