A humidity reduction duct assembly for attachment over the air inlet of an evaporative cooler having a tray assembly insertable therewith transversely thereacross intermediate the duct inlet and the cooler inlet so that air drawn through the duct passes across and through the tray assembly. The tray assembly is formed of a pair of spaced rigid members having a plurality of foraminous cylinders disposed therebetween in spaced parallel relationship to each other and filled with an air permeable desiccant. The duct removes excessive humidity from the ambient air and enhances the efficiency of the evaporative cooler.
