摘要： A filter system including a housing with an intake and an outlet, a pleated carbon filter disposed between the intake and the outlet for filtering out vapors entering the intake, and a hydrophobic solution dispersed about the pleated carbon filter to inhibit adsorption of water thereby increasing the adsorption capacity of the pleated carbon filter especially in high relative humidity environments. The hydrophobic solution is selected so that it does not decrease the adsorption capacity of the carbon filter. Also disclosed is a method of making such a filter.
