1. An airflow conditioning device comprising:
a first channel defining a first airflow pathway through the airflow conditioning device and a second channel defining a second airflow pathway through the airflow conditioning device;
a heat and moisture exchanger disposed in the airflow conditioning device, the first and second channels each passing through the heat and moisture exchanger, the heat and moisture exchanger comprising a plurality of air-permeable barriers separating the first airflow pathway from the second airflow pathway, at least one of the plurality of air-permeable barriers comprising:
a layer of a microporous film comprising a first surface and a second surface opposite of the first surface, and
a water vapor permeable resin layer adjoined to the first surface, the second surface, or both the first and second surfaces of the microporous film so as to form a discontinuous nonporous coating thereon.
