1. A heat moisture exchanger (HME) comprising:
a first housing having a first port;
a second housing having a second port attached to a first housing cylinder;
at least one foam insert configured within the first housing;
at least one O-ring for preventing air from escaping from the first housing;
an angled diverter of the second housing;
wherein the first housing and second housing form a rotating cylinder that is configured to create a rotational bypass channel between the first port and second port, wherein the angled diverter is configured to direct air through the rotational bypass channel in a bypass mode, and the angled diverter is configured to direct air through the at least one foam insert in an HME mode;
a support member of the first housing, the support member comprising a first flat surface, a second flat surface opposite to the first flat surface and a third flat surface extending from the first flat surface to the second flat surface;
a bypass chamber at least partially defined by the first flat surface of the support member, wherein the bypass chamber forms part of the rotational bypass channel;
an HME chamber at least partially defined by the second flat surface of the support member, wherein the at least one foam insert is positioned in the HME chamber, and the at least one foam insert is in a shape of a half-cylinder;
wherein the angled diverter forming a planar plate comprising a first flat surface that is angled relative to a longitudinal axis of the HME, the first flat surface of the angled diverter configured to direct air through the rotational bypass channel in the bypass mode, and the first flat surface of the angled diverter is configured to direct air through the at least one foam insert in the HME mode;
wherein the angled diverter further comprises a second surface opposite to the first flat surface of the angled diverter and a third surface that extends from the first flat surface of the angled diverter to the second surface of the angled diverter, the second surface of the angled diverter is configured to face the at least one foam insert in the bypass mode and does not face the bypass chamber in the bypass mode and the second surface of the angled diverter is configured to face the bypass chamber in the HME mode and does not face the at least one foam insert in the HME mode; and
wherein the third surface of the angled diverter is configured to directly face the third flat surface of the support member in the bypass mode and configured to directly face the third flat surface of the support member in the HME mode.
