I hope you already have a filter at the intake? Installing filters at the outlet vents would result in the dust accumulating there and impeding the airflow, which can't be good for your AC. Still, if you insist, I suppose you could buy the kind of furnace filter that can be cut to size.

Just a wild guess, but could the dust be caused by a hole in the ducting leading to the basement?

That's my guess too.
1. You've eliminated dust in the ducts.
2. You have a filter (changed regularly?) at the intake.
3. Dust has to come from somewhere. Are you sure it's coming from the vents in the basement? If it's only dusty in the basement, but nowhere else, maybe there's another dust source.
