With data covering 3,000 cities in more than 100 countries, the World Health Organisation (WHO) says that more than 80 percent of people living in urban areas that monitor air pollution are exposed to quality levels that exceed WHO limits. While nanotechnology has previously been applied to the problem, earlier solutions are energy intensive to produce and require specialized equipment. Using a quick and easy to make nanofiber solution, researchers from the National University of Singapore’s (NUS) Department of Materials Science and Engineering have found a way to turn non-woven mesh into high quality air filters.
