How to Filter Items Using a Copper Hopper

Configuring Item Filters

The Copper Hopper provides built-in item filtering across its 5 inventory slots, eliminating the need for complex redstone comparator setups.

1. Place your Copper Hopper facing into your destination container or inventory line.

2. Open the Copper Hopper interface by interacting with it.

3. Place the specific item type you want to filter into any of the available slots. You can configure up to 5 different item types per hopper.

4. Once an item is placed in a slot, the hopper will only pull and push items that match the filtered types. Any item not matching your designated slots will be ignored.

Understanding Filter Retention

To prevent the filter from breaking when items move through your storage system, the Copper Hopper includes automatic retention.

  • The hopper always keeps at least one of each filtered item inside its inventory.
  • Because that single item remains locked in place, the filter continuously stays active without running out of reference items.
  • Feed an input inventory into the top of the Copper Hopper to begin routing matching items automatically.
