Particulate pollution has led to catastrophic health and environmental consequences. As a result, new approaches have been done to increase the efficiency of the air filtration equipment. Here a novel nanofibrous air filter made via electrospinning process is demonstrated, which has attractive attributes of high filtering efficiency and low resistance to air flow. The filter could be manufactured with a transparency of 90 % and an efficiency of > 85% under intense smoke exposure. Consequently, the filter could be applied as a muzzle, an alternative for catalytic converters of car exhausts or fabric filters used in the treatment of factories emissions. Additionally, the filter is made from hydrophilic polyacrylonitrile which makes it recyclable and efficient in humid circumstances.
