A device is provided for extracting water from atmospheric air (8) having a free-flowing adsorbent or absorbent (3, 13), in particular a saline solution (3), having a hygroscopic salt for the adsorption or absorption of water, the adsorption or absorption being provided at least along an adsorption or absorption section (7), which realizes a high yield of (potable) water per unit volume of the structure or of the absorbent/adsorbent (3), a decrease in the assembly effort and a stabilization of the process. This is achieved according to the invention in having a free-flowing adsorbent (3, 13) or absorbent (3, 13) disposed at least along the adsorption or absorption section (7) essentially on a guide element (1, 16, 19, 22, 24) for guiding the adsorbent (3) or absorbent (3), in particular on a presettable track.
