ABSTRACT:
Filtration media are disclosed for use in high efficiency air filters for filtering particulate matter in air. The media make use of at least one layer of fibers having a diameter less than 1000 nanometers sandwiched between two scrim layers to achieve high efficiency particulate air (HEPA) filtration performance at relatively low pressure drops.
