NOVELTY - A filter media comprises a filter substrate and a fiber layer or fiber web comprising a continuous fine fiber layer. The fiber has a diameter of 0.001-5 microns and an active particulate dispersed in the fiber layer or fiber web. The particulate comprises 0.1-50 vol.% of the layer or web and the layer or web has a thickness of 0.0001-1 cm and a solidity of 0.1-70% (1-50%). The active particulate comprises 0.001-10 kg/m2 of the layer or web. The fine fiber layer is heat treated forming a porous membrane.    USE - For particle filtration and chemical filtration, combination particle filter and chemical filter for gas turbine application, chemical filter for gas turbine systems, high flow applications in the semiconductor industry for fan assemblies, and full filter fabrication locations or labs, tool mount filter for semiconductor applications within clean rooms, high flow applications in ceiling grids for clean room applications, filtration for gasoline, natural gas or diesel powered engine, inlet filtration for air compressors, inlet filtration for dust collection equipment, vacuum cleaner filters, acid gas removal from air, cartridges for driers, CBRN protection materials, wound care, HVAC applications, cabin air filtration, room air cleaner, fuel filter, lube filter, oil filters, liquid filters, air filter for fuel cell application, process filters, insulation material, filters for disk drives, filters for electronic enclosures, chromatographic separations, bio-separations.    ADVANTAGE - The media provides figure or merit, filtration efficiency, filtration permeability, depth loading and extended useful lifetime characterized by minimal pressure drop increase. The structure obtained improved filtration properties in combination with resistance to increased pressure drop, improved efficiency, and the ability to remove both a particulate non-reactive load and a reactive gaseous or particulate load from a mobile fluid stream passing through the fiber layer.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) an element comprising the filter media;    (2) a method for filtering a fluid;    (3) a method of removing moisture from an air stream; and    (4) a flexible display for an electronic device.
