If the exterior wind direction doesn't locate the exterior outlet downwind of the intake, one could potentially install a short exterior duct to add separation, as in step 13 of this DIY HRV, https://www.loudawson.com/17884/how-to-build-air-cross-flow-heat-exchanger/ https://www.loudawson.com/17884/how-to-build-air-cross-flow-.... For the interior ports, 45-degree angled vents can reduce overlap between the airflow directions. Without the HRV, air would be moving in and out of the same window anyway, without any structural separation. Amazon reviews for the Bionaire reported both energy savings and air quality improvement, so it worked for some people. For homes, there are DIY full-sized HRVs, with custom ducting, https://ecorenovator.org/forum/showpost.php?p=26861&postcount=291 https://ecorenovator.org/forum/showpost.php?p=26861&postcoun...
