Nanofibres benefit air filtration

At the National University of Singapore (NUS), thin, see-through air filters have been made from a new nanofibre solution. They are capable of removing up to 90 per cent of PM2.5 particles and are said to achieve air flow of 2.5 times better than conventional air filters. As an added bonus, they can also improve natural lighting and visibility while blocking harmful ultraviolet (UV) rays.
