You're probably doing it wrong. Which side are you trying to pull it from? You can extract the "input" side, for example iron ore through the top. The bottom doesn't output anything, don't try that. All other sides (left, right, front, back) will extract the "output" side, for example iron ingot.

Make sure the filter/transposer is facing the correct way. The small hole is output for tubes or chest.

You also need a valid destination if sending it through pneumatic tubes. Some chests doesn't work, for example silver. Try with the standard wooden one or no tubes/chest at all. Just the filter. It will spit items out on the ground.

Also make sure you're sending an impulse to your filter with a timer or anything similar.
