+# Create or edit filters in model-driven app views
+
+<a name="BKMK_CreateOrEditViewFilters"></a>   
+
+The filters in a Power Apps view are important to the value provided by the view. Which filters are applied determine which records appear in the list by default. You can add or edit a filter for the columns that you include in a view by selecting the column and selecting **Filter by**. You can also use the Filters editor in the view designer. Use the Filters editor to add or edit filters for any fields in the view entity or any fields in a related entity. 
+
+In this topic, you create or edit filters by performing the following tasks:
+
+-   [Edit or remove a filter condition](create-edit-view-filters.md#edit-or-remove-a-filter-condition)
+
+-   [Add or edit conditions to the filter](create-edit-view-filters.md#add-or-edit-conditions-to-the-filter)
