　　DuPont melt-spun nanofibrous electret filtration media consists of the stand-alone electret nanofibrous web comprising a single source randomly intermingled fiber network with self-composite of nanofibers and microfibers with the average diameter of total fibers less than 1000 nm.As improved air filtration media for personal respiratory protection and environmental air quality,it yields the better breathability with lower resistance due to the much lower packing density of fibers,the better protection with the improved filtration efficiency due to the more effective electrostatic charge to surfaces of individual fibers.
