In Power BI, both filters and slicers are used to limit or refine the data displayed in reports.
However, they differ in how they are applied, where they are used, and how users interact with them.
1. Purpose and Usage #
- Filters are primarily used by report developers to control what data appears in visuals, pages, or the entire report.
- Slicers, on the other hand, are visual tools placed directly on the report canvas to let end-users interactively filter data themselves.
Example:
A developer might use a filter to show only current year’s data, while an end-user can use a slicer to switch between different product categories.
2. Placement and Visibility #
- Filters are applied in the Filter pane (available at the visual, page, or report level). They are not visible to report viewers unless the pane is opened.
- Slicers are placed directly on the report page, making them visually accessible and easy to use.
3. User Interaction #
- Filters are mostly static — configured by the report author during report design.
- Slicers are interactive, allowing viewers to change the data context dynamically while viewing the report.
4. Scope #
| Feature | Filters | Slicers |
|---|---|---|
| Levels | Visual, Page, Report | Page-level (can sync across pages) |
| Visibility | Hidden in Filter pane | Visible as a report visual |
| Control | Controlled by report author | Controlled by end-user |
| Purpose | Data restriction | Data exploration |
| Interactivity | Limited | High |
5. Sync and Consistency #
- Filters can apply to multiple visuals or pages depending on their scope.
- Slicers can be synced across multiple pages using the Sync Slicers feature for consistent filtering.
Filters are used to define and control what data is displayed, while slicers are used to interactively explore and filter data during report viewing.
In simple terms — filters are backend controls, and slicers are front-end interactive tools for users.
