# Drop items with Filter in Duaer

In Duaer, Filter keeps only the items that match. Items that do not match are dropped. There is no second output for them.
## Keep only what matches

1. Search for Filter and connect it after the node you want to narrow.
2. Add a condition under Conditions. For example, the string field status equals paid.
3. Combine extra conditions with AND or OR.
4. Select Execute step. The output contains only the matching items.

When the items that do not match still need another path, use If. Refer to [Split a Duaer run with If and Switch](/flow-logic/splitting.md).
## Questions

### Does Filter in Duaer send rejected items to a false output?

No. Filter has one path forward. Items that do not match are dropped at that step.
