The invention relates to a bacteriostatic dehumidifying element that includes additives which inhibit the growth of microorganisms. The dehumidifying element is produced by a method that comprises the steps of: a) providing a piece of paper, such as facing paper and/or fluted paper; b) immersing the paper in a highly concentrated waterglass solution at a temperature c) in the range of 45-95 DEG C, where said highly concentrated waterglass solution has a viscosity of at least 350 mPa.s at a temperature of 45 DEG C; d) cooling the immersed paper with air at a temperature of at highest 35 DEG C, and preferably at highest 25 DEG C; e) with a starting point from the paper in step c), producing a waterglass-impregnated fibre matrix followed by a chemical conversion of the waterglass on said paper with the aid of known processes for producing a moisture exchange element; and f) impregnating the moisture exchange element of step d) with one or more aqueous solutions of an hygroscopic salt and a water soluble substance that inhibits the growth of microorganisms. |
