HVR links of interest:

Here's one from UK that is a cointer-flow and claims 80% efficiency. 80 percent seems to be a suspiciously round number to me. Not much detail pictured, but I'd guess it to be a cross-flow that has been flattened out like a squashed "X" and called a cross-flow.

Here's a paper that is done by the University of South Dakota. Note the efficiency numbers there. They aren't trying to sell anything.

Here's a FAQ done by the University of Minnesota.
Common Questions about Heat and Energy Recovery Ventilators

Here's a Guy named Marsen who installed one (Airiva) in his workshop in Maine. Well documented. Curiously, he never comments on the quality of the air after the installation.

Here's a paper that focuses on using the ERV in primarily hot humid climates.
