  • AIR FILTER FOR HIGH-EFFICIENCY PM2.5 CAPTURE
    Publication number: 20230277967
    Abstract: Described here is an air filter comprising a substrate and a network of polymeric nanofibers deposited on the substrate, wherein the air filter a removal efficiency for PM2.5 of at least 70% when a light transmittance is below 50%. Also described here is an electric air filter comprising a first layer adapted to receive a first electric voltage, wherein the first layer comprises an organic fiber coated with a conductive material. Further described is an air filter for high temperature filtration, comprising a substrate and a network of polymeric nanofibers deposited on the substrate, wherein the air filter has a removal efficiency for PM2.5 of at least 70% at a temperature of a least 70° C.
