Abstract: An apparatus for preparing hot melt blown adhesion type functional hybrid filter is provided to remove significantly the noxious ionic gas. A conveyor belt(3) moves a filtering member(1) and is driven by a motor(2). A hopper(4) projects the hot melt viscosity materials(6) to be coated on the filtering member. A melting extruder(5) melts and extrudes the hot melt viscosity materials projected from the hopper. A multi projection nozzle(7) is located at the upper portion of the conveyor belt and projects the hot melt viscosity materials extruded from the melting extruder. An air compressor(8) is connected with the multi projection nozzle and projects the hot melt viscosity materials together with the heated air with high pressure.
