ABSTRACT:
Air-cleaning filter element prepared by applying a pressure-sensitive adhesive agent to at least a pair of three-dimensionally mesh-structured elastic-flexible webs, disposing evenly an adsorbent material, such as activated carbon, in a size range of 0.5 mm to 10 mm in diameter between said pair of elastic-flexible webs and pressing the same elastic-flexible webs together as superimposed. The air-cleaning filter element is free from such a deterioration of the adsorbent material as caused by an adhesive and any significant fluid pressure drop on passage of fluid.
