That pic is a good idea.
But you would need some kind of switch.
So it could filter the air every few hours for about 5 minutes.
For the humidity and fresh air .
If you attatched a splitter and had one side open and the other side closed most the time.
Then you use dampers to open and close on a timer.
This very extensive but very effective.
