An adsorption-desorption material having a high carbon dioxide adsorption-desorption capability, a low pressure loss, a high thermal diffusion efficiency, and high resistance to repeated stresses, e.g., expansion and shrinkage, as well as an adsorption-desorption apparatus including the adsorption-desorption material, is provided. The adsorbent is composed of a three-dimensional network skeleton structure or a structure having three-dimensional network voids, the structure constructed by a compound having a carbon dioxide adsorption-desorption capability. The carbon dioxide adsorption-desorption apparatus is provided with this adsorbent.

A fluid cleaning filter of the present invention consists of a composite matrix composed of a pleated substrateconfigured into a pleated shape and an active carbon-containing layer, wherein the pleated substrateis made of polyurethane foamhaving a three-dimensional network skeletal structure, and the composite matrix is configured into a cylindrical shape. A filtering medium layermade of fibers is formed on the surface of the polyurethane foamfacing the active carbon-containing layer. The fibers of the filtering medium layer maybe electrostatically charged. The fluid cleaning filter exhibits good efficiency of dust collecting and deodorization even when a fluid flows through the filter at high rate.
