A hopper-based Minecraft item auto-sorter sends chosen items into designated chests. The standard module uses a filter hopper stocked with the target item and filler items, a comparator to read the hopper’s contents, and redstone circuitry to control the output hopper. For a storage array with adjacent modules, choose an overflow-protected design and use the exact counts for that design and your edition.
How a hopper item sorter works
Items travel through a hopper line. At each sorter module, a filter hopper holds the item that module should recognize, along with filler items. A comparator reads the filter hopper’s inventory state; the redstone circuit uses that signal to control the hopper below. When a matching item passes through, the module routes it toward its output chest.
The filter’s contents are part of the circuit, not just a label. Filler counts and the arrangement of the circuit must match the specific design you build. Do not combine the hopper recipe from one version of a sorter with the redstone layout from another.
Choose a design before setting up the filter
A community-maintained tutorial documents more than one filter configuration. Its counts are specific to those designs, so use the schematic for the module you have selected.

| Configuration described | Filter contents | Important qualification |
|---|---|---|
| Basic hopper design | 41 target items and four filler items, one in each remaining slot | The tutorial recommends renaming the filler items. Counts belong to this basic setup. |
| More compact arrangement | One target item and 21 cheap filler items | This is a different design; do not transfer its counts to the basic design’s circuitry. |
In either case, use inexpensive items that stack to 64 as fillers where the chosen design calls for them. Renaming fillers helps distinguish them from ordinary items while building and servicing the filter. The tutorial does not establish these counts as universal recipes for every sorter layout or game edition.
Plan for overflow in a storage array
Overflow protection matters when sorter modules are tiled side by side. If a filter hopper fills beyond what its design expects, its changed inventory signal can interfere with neighboring modules. A design that works as an isolated demonstration is not automatically safe to repeat across a large storage wall.
The tutorial identifies a repeater-protected, resource-optimized design as working in Java 1.18+ and Bedrock, and recommends overflow protection for arrays. Treat that compatibility as a note about the named design, not a guarantee for every sorter or every later game update. The same tutorial warns that some older designs, types I–IV on its page, can experience redstone torch flicker burnout in Java 1.18 and later at a steady 2.5 items per second.
Check edition and item stack size
Java and Bedrock can require different filter contents for some layouts. The tutorial says one hybrid design may need 20 non-filter items in its Bedrock Edition part instead of 21. Its variation for items that stack to 16 calls for 15 or 14 non-filter items, depending on the part. These adjustments apply to those specific designs; follow the edition-specific schematic rather than substituting counts from another configuration.

Before building, identify your edition and version, the exact sorter design, and whether the target item stacks to 64 or 16. The tutorial is community-maintained and its circuit behavior has not been independently verified here against current game versions, so validate the chosen schematic in your target edition and version before duplicating it.
Special filters for potions, books, and shulker boxes
Some items call for a different filtering mechanism rather than the standard stackable-item hopper filter. The tutorial describes designs that use containers with restricted inventory behavior, including brewing stands for potions, chiseled bookshelves for books, and shulker boxes for shulker boxes. These are advanced alternatives: their setup and timing constraints differ from a standard module, so use the matching schematic rather than treating them as a simple filler-count adjustment.

Use the selected design’s documented specifications to decide whether it suits your storage system. The tutorial reports transfer rates of 2.5 items per second for several hopper-speed designs and 2 items per second for one special filter. Those are design-specific reported rates, not independent performance tests.
- Edition compatibility: Check whether the design’s notes cover your edition and version.
- Overflow protection: Prefer a protected design for a tiled storage array.
- Stack size: Confirm the filter recipe supports the target item’s stack size.
- Transfer rate: Compare only rates reported for the specific designs you are considering.
- Complexity and materials: Account for the full circuit and its components, not only the filter hopper.
- Item type: Determine whether the target item needs a specialized filter.
For the standard approach, the practical sequence is to select one complete schematic, identify its edition and stack-size requirements, build the filter with that schematic’s exact contents, and test the module before extending it into an array.
