Why is my Sandustry Filter not working?
Check the selected material, filter mode, configured element and liquid/gas options.
FILTER / SCOPE
Sandustry Filter Scope Checker: Test Material Rules
Not sure why a Filter is letting a material through or blocking something you need? Select the material, the element configured on the Filter and the filter mode. Set the liquid and gas options, then check the expected result before changing your factory.
Filter settings
Reaction across a Filter
A reaction across the boundary needs both input elements and its output to be allowed.
Choose Filter settings and check the result.
Boundary reaction
The Filter allows the two inputs and the output; the boundary does not block this reaction.
Test one material at a time
Choose the material you want to test, select the element on the Filter and choose the relevant mode. The checker shows how those settings apply to the selected material.
Check liquid and gas behavior
Use the liquid and gas options when testing a rule that may affect more than solid materials. Make sure the settings match the Filter you are trying to reproduce in the game.
Frequently asked questions
Can I test a material before building the Filter?
