- PM2.5 AIR FILTER FOR HIGH-EFFICIENCY PM2.5 CAPTURE

摘要

An air filter comprising a substrate and a network structure of polymeric nanofibers attached to the substrate is described herein wherein the air filter has a removal efficiency for PM _2.5 of at least 70% when the light transmittance is below 50%. Also disclosed herein is an electric air filter comprising a first layer adapted to receive a first electrical voltage, wherein the first layer comprises organic fibers coated with a conductive material. Further, an air filter for high temperature filtration comprising polymeric nanofibers adhered to a substrate and a substrate is described, wherein the air filter has a removal efficiency for PM _2.5 of at least 70% at a temperature of at least 70 ° C.
