We installed something like this, but for the purpose of getting fresh air into the house (instead of circling stale air over and over and increasing the CO2 levels). Our setup is:
Fresh air / circulated air -> Perfect 16[1] -> HVAC
I highly recommend it. You can also get an ERV or HRV to utilize heat/humidity when bringing in outside air.
