I've been doing this wrong all along then? I've got my filter on the outtake side. What is the difference I wonder.

The difference is your "fan/blower" will not function as well as a "compressor".
You want to vent towards the largest, least constrained volume available, from higher constraints towards lower constraints.

From my understanding the biggest difference is the blades not getting covered in grime, because you're pre-filtering the air.
I've also heard airflow dynamics arguments, but I feel like I've heard them argued in both directions.

You can use two fans, one on intake, one on exhaust. Or three, if you have a particularly fine filter. But building another whole unit to run in another room might be better.
With a #9, one-inch filter, a single fan does fine.

Outtake muffles agitation from the airflow.
Intake still allows the air coming out to be more turbulent, mixing with the existing air better and giving it more "throw" in larger spaces.
