Polyimide-nanofiber air filters Abstract: We've crafted high-efficiency (>99.5%) polyimide-nanofiber air filters designed specifically for removing high-temperature PM particles. These filters boast exceptional thermal stability, maintaining consistent removal efficiency between 25-370 °C. Notably, they offer high air flux with minimal pressure drop and can operate continuously for over 120 hours even with PM indices exceeding 300. Field tests have demonstrated their ability to effectively remove over 99.5% of PM particles from car exhaust, even at elevated temperatures.
