Item Filter

Item Filter is a Minecraft Fabric mod that adds a configurable, high-speed item filter block.

It works like a hopper, but with filter slots, a toggleable filter mode, and adjustable transfer speeds of up to 640×. Choose which items are allowed to pass through, or disable filtering to transfer any item.

How It Works

Place the Item Filter like a vanilla hopper.

Items can enter from the top through hoppers, be pulled directly from inventories above, or be collected as dropped items.

Items leave through the direction the block is facing.

Whenever possible, items transfer directly between inventories without passing through the internal storage slots.

Inside the GUI:

• Filter slots define which items are allowed to pass.
• Items slots work as the internal inventory.
• Mode ON allows only filtered items.
• Mode OFF allows any item to pass through.

When filter mode is ON, only items matching the filter slots can enter the Item Filter.

When filter mode is OFF, the Item Filter allows any item to pass through.

Transfer Speed

Starting with version 1.2.0, Item Filter features high-speed transfers with adjustable throughput.

Transfer speed ranges from 1× to 640×, with 640× enabled by default.

Transfer Speed Reference

Setting	Maximum Transfer Rate
1×	10 items/s
32×	320 items/s
64×	640 items/s
128×	1,280 items/s
256×	2,560 items/s
320×	3,200 items/s
640×	6,400 items/s

Transfer rates are theoretical maximums at 20 TPS. Actual performance depends on available items, destination capacity, inventory restrictions, and server performance.

Configuration

With Mod Menu installed, navigate to:

Mods → Item Filter → Configure → Transfer Speed

Choose your preferred speed and save the configuration.

In single-player, transfer speed can be configured locally. On dedicated servers, the server administrator controls the transfer speed for all players.

Mod Menu is optional and is not required on dedicated servers.
