Power BI Slicers vs Filters: What’s the Difference and When to Use Each?

Slicers in Power BI provide an intuitive way for users to filter and explore data. While they enhance interactivity and usability, careful implementation is necessary to avoid performance issues. By following best practices, slicers can significantly improve report efficiency and user experience.
In Power BI, a slicer is a visual filter that allows users to interactively filter data and explore specific subsets of information within a report.
The slicer is a key visual used to filter other visuals in a report. It is commonly added to report pages because it provides an easy and intuitive way for users to filter data. As a report creator, you can customize the slicer's layout, formatting, and functionality to fit your needs. By default, a slicer filters all visuals on the same page. However, you can adjust visual interactions to limit filtering between specific visuals. Additionally, sync slicers allow you to filter visuals across multiple pages.
When to Use a Slicer in Power BI
Slicers are useful when you want to:
- Provide easy access to filters by displaying commonly used or important filters directly on the report canvas.
- Make filtering more visible so users can instantly see which filters are applied without opening a drop-down menu.
- Filter by hidden columns that arenβt shown in the data tables but are still useful for analysis.
- Enhance report focus by placing slicers next to key visuals, making it easier to interact with data.
