A member of the Shanghai Jiao Tong University research team that invented a new air-purifying device demonstrates the machine. The device’s technology can prevent secondary pollution that existing air purifiers can create if not used properly.
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.
Professor Shangguan Wenfeng, who led the research project, said at a news conference on Monday that current air purifiers clean the air mainly by absorption and filtering, but this technique has problems.
“For example, the filter needs to be replaced regularly because it will easily reach the saturation point, which might lead to further pollution,” he said.
Also, while some machines cannot filter smaller pollutants well, the school’s new technology overcomes that shortcoming, he said.
