Hopper filters: sort items without redstone

Every hopper gets a filter slot. Put one item in, and the hopper only accepts that item: a row of filtered hoppers makes a complete item sorter, without a single comparator or redstone torch.

How it works

Item sorters without the redstone.

  • Every hopper gets a filter slot: put one item in, and the hopper only accepts that item.
  • A bundle or a shulker box in the filter slot lets through every item it holds. An empty one filters bundles or shulker boxes, like any other item.
  • The filter compares the item, not its enchantments or name.
  • A row of hoppers with filtered hoppers underneath makes a full item sorter.
  • Speed, redstone locking and comparators stay vanilla.
  • Filtered hoppers are recognizable by the iron grate inside.

Questions

How do I build an item sorter with filtered hoppers?

Send your items along a line of hoppers. Under each hopper of the line, place a filtered hopper leading into a chest: each one pulls out only its item, and the rest carries on down the line.

Can one hopper filter several items?

Yes: put a bundle or a shulker box holding those items in the filter slot, and every item inside it goes through.

Does the filter care about enchantments or names?

No, it compares the item only: any diamond sword goes through a diamond sword filter, enchanted or renamed.

Does it break my redstone builds?

No. Without a filter, a hopper works exactly as in vanilla, and speed, redstone locking and comparators never change.
