Air filter for high efficiency PM2.5 capture

摘要

Described herein is an air filter comprising a substrate and a network of polymer nanofibers deposited on the substrate, wherein the air filter has a PM2. 5 has a removal efficiency of at least 70%. Also described herein is an electrical air filter that includes a first layer adapted to receive a first electrical voltage, wherein the first layer is coated with a conductive material. Containing organic fibers. Further described is an air filter for high temperature filtration comprising a substrate and a network of polymer nanofibers deposited on the substrate, wherein the air filter is at a temperature of at least 70 ° C. to PM2.5. It has a removal efficiency of at least 70%.
