# Filtering

### Overview

Quilter provides straightforward filters that let you quickly pinpoint candidates that meet your design criteria. 

When you submit your layout job, if you include Design Parameter preferences (see [select-your-stackup](https://docs.quilter.ai/using-quilter/select-your-stackup "mention")), they'll be automatically used as filters to help you narrow down to the candidates that match your preferences.

### Using filters

Here are a few notes on using filters:

* Updating filters changes the layout candidates visible in your candidate list in real time.&#x20;
* You can click the `Reset Filters` button to clear all filters and view all candidates explored by Quilter throughout the layout job.&#x20;
* The `Show 100% routed candidates only` filter is automatically applied to all jobs, and you can manually clear it at any time to see <100% routed layout candidates.
