Abstract
A heat moisture exchanger (HME) having a rotatable bypass channel includes a rotating cylinder having a first port and an outer cylinder having a second port attached to the rotating cylinder. A half-cylinder shaped foam insert is configured within the rotating cylinder to heat and moisturize air moving through the HME. The cylinder is configured to create a rotational bypass to air using an angled diverter moving between the first port and second port such that the rotating cylinder can be moved between a position for engaging the foam insert and a bypass position for bypassing the foam insert.
