University unveils new air purifier technology
China DailyA member of the Shanghai Jiao Tong University research team that invented a new air-purifying device demonstrates the machine. Du Xin / for China Daily Innovation removes pollutants by electrostatic and catalytic processes Chinese researchers have developed a new technology to clean up indoor air pollution that avoids secondary pollution that existing air purification products in the market can create if used improperly. The new air purifier, developed by a research team from the School of Mechanical Engineering at Shanghai Jiao Tong University, removes indoor pollutants from air through physical and chemical methods. Because Shanghai air quality was classified as “good” at the time, researchers made a smoggy indoor environment in a 30-square-meter room by lighting six cigarettes. The research team said the retail price of the new air purifier would be competitive with similar machines on the market from big international brands like Blueair, Daikin, Philips and Siemens.
