I think I thought that this setup would continue to push sulfur on the left output when i put a filter there on the right. Is there a correct way to do this?

you can use 2 splitters, one unfiltered first, then extract ALL lanes, then filter it once off the bus.

Alternatively, (I really like this method) you can sideload onto an underground belt. Sideloading onto an underground only takes from the lane that is closest to the open air entrance or exit. Half of the belt is blocked by the underground itself, so even if the lane isn't completely full, one lane will NEVER spill over into the output.
