Abstract
A heat and moisture exchanger consists of a folded sheet of water permeable paper having a plurality of folds. Separators are placed between said folds to provide air passages. Air is directed in one direction through the folds on one side of said folded paper. The return air flows in the opposite direction through said folds on the other side of said folded paper. Water and heat are transferred through the paper from one air stream to the other air stream flowing in the opposite direction.
