How to Filter Specific Items in a Demagnetizer

Sometimes you want your item magnet to keep cleaning up stray blocks—like cobblestone or dirt—around your base while leaving specific crafting ingredients alone on the ground. Both Demagnetizer blocks include built-in item filtering so you only block magnets for the exact items your automation uses.

Setting Up Item Filters

1. Gather one sample of each item involved in your in-world automation (both the input ingredients and the finished output items).

2. Right-click your placed Demagnetizer or Advanced Demagnetizer to open its GUI.

3. Locate the filter settings and filter slots inside the interface.

4. Place your sample items into the available filter slots to define which items should be affected by the block.

Handling Complex Setups

If your automation processes many different items at once and you run out of room in the standard Demagnetizer's interface, swap the block out for an Advanced Demagnetizer. The advanced tier provides extra filter slots alongside its expanded radius, letting a single block manage multi-ingredient crafting areas without interfering with normal item pickup.
