PURPOSE: A filter assembly for the pan-type cooling device is provided to prevent the reduction of the air permeability, and the increasing of the differential pressure by preventing the blockage and the deformation of the air gap and the deformation of the filter media. CONSTITUTION: The filter assembly (150) comprises a multi-layered nonwoven layer; and a complex fiber layer (200) which laminates each nonwoven layer between nonwoven layers. The complex fiber layer comprises a low melting fiber. A part or whole of the low melting fiber is melted or softened. |
