A gas purifier Z having an air passage Q in which are arranged an adsorbing/removing unit B having a regenerable adsorbing member (9) for adsorbing chemical contaminants in unclean air W' and for separating contaminants adsorbed through regeneration, and a gas purification unit A for separating the contaminants in the unclean air W' into liquid and removing the contaminants by performing gas/liquid contact through a porous film. Water-soluble contaminants are separated and removed at the gas purification unit A, and chemical contaminants are adsorbed and removed at the adsorbing/removing unit B.
