Sandustry Filter Guide: Best Setups and How to Stop Clogs

What a Filter should do

A Filter should make one routing decision obvious: send the selected material to a named destination and give every other material a safe overflow route. A Filter with no overflow is a future clog.

Gold filter setup

Place the Gold route below or beside the Shaker output, then test it with a small batch before connecting the whole factory. Keep the Gold collector separate from Residue storage so a wrong filter choice cannot contaminate your progression stockpile.

Wet Sand and Lava routes

Use separate filter rows for Wet Sand and Lava. Label or visually group each route, leave a maintenance gap, and avoid stacking inputs where a player cannot inspect the material layers.

Anti-clog checklist

• Every output has a destination or overflow bin.
• Filter order matches the material priority.
• The route is not relying on a full storage container as a buffer.
• Shakers have room for Residue to leave the surface.
• A failed filter can be bypassed without rebuilding the factory.

When a Filter is not working

Check the selected material, the direction of flow, and whether the output path is full. If the filter works for one item but not another, test density and input order before adding more machines.
