# Filters {% embed url="" %} Filters are conditions added to your data layers to only show a subset of features in the map, in the [Table View](/layers/table-view.md) or as the input for [Transform](/layers/spatial-analysis.md). ## Adding filters to a layer Filters work on all data types, including text, numbers, booleans and dates. Filters can be added to a layer in two ways: * Directly from the Table View by clicking on a column, then on **`Add filter...`** * In the **`Filter`** tab of the style editor, by clicking on the **`Add filter`** button.

## Creating new filtered layers It can be useful to create new derived layers that contain just the filtered data from the original. This can be achieved by clicking on the **`# features`** text in pink, then selecting the **`Update in new layer`** option from the dropdown menu.

## Filters & Transformations [Transformations](/layers/spatial-analysis.md) from the Spatial Analysis toolkit can use filtered layers as input, which is very convenient for quick data wrangling & exploration. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
