What Are The Different Types Of Filters In Power BI Reports
Filters are the backbone of interactive reporting in Power BI. They control which data is visible in each visual, on each page, and across the entire report. Understanding the different filter types and when to use each one is essential for building reports that are both powerful and user-friendly. At EPC Group, we design enterprise Power BI reports with layered filter strategies that balance self-service exploration with governance-controlled data access for organizations with strict compliance requirements.
1. Visual-Level Filters
Visual-level filters apply to a single visual (chart, table, card, etc.) and do not affect any other visual on the page. They are the most granular filter type available.
- Applied by dragging a field to the "Filters on this visual" section in the Filters pane
- Only affects the specific visual they are applied to, even if other visuals use the same data
- Useful for showing Top N results in a chart while other visuals show all data
- Can filter on fields that are not present in the visual itself (e.g., filter a sales chart by a product category not shown in the visual)
- Can be set to Basic (dropdown list), Advanced (contains, starts with, etc.), or Top N filtering modes
- Authors can lock visual filters so end users cannot modify them from the Filters pane
Best practice: Use visual-level filters when you need one visual to show a subset of data that differs from the rest of the page. For example, a "Top 10 Products by Revenue" chart on a page that otherwise shows all products.
2. Page-Level Filters
Page-level filters apply to all visuals on a single report page. They are the most commonly used filter type for creating focused, topic-specific pages.
- Applied by dragging a field to the "Filters on this page" section in the Filters pane
- Every visual on the page respects the page-level filter, ensuring consistent data context
- Commonly used to create region-specific, department-specific, or time-period-specific pages
- End users can modify page-level filters unless the author hides or locks the Filters pane
- Page-level filters persist when navigating away from and back to the page within a session
Best practice: Use page-level filters to define the scope of an entire page. For example, set a page filter for "Region = North America" to create a dedicated North American performance page.
3. Report-Level Filters
Report-level filters apply to every page and every visual in the entire report. They are the broadest filter scope and are typically used for global constraints.
- Applied by dragging a field to the "Filters on all pages" section in the Filters pane
- Affects every visual on every page of the report without exception
- Commonly used to exclude test data, filter to the current fiscal year, or limit to active records
- Authors can hide report-level filters from end users to enforce data governance policies
- Report-level filters are evaluated before page-level and visual-level filters in the filter chain
Best practice: Use report-level filters for global data quality rules that should never be overridden by end users. For example, exclude records where Status = "Deleted" or filter to the last 3 years of data across the entire report.
4. Drillthrough Filters
Drillthrough filters enable users to right-click on a data point in one visual and navigate to a detail page that is automatically filtered to that specific data point. This is one of Power BI's most powerful interactive features.
- Configured by adding fields to the "Drillthrough" section on the target (detail) page
- When a user right-clicks on a data point (e.g., a specific customer or product), Power BI navigates to the drillthrough page with that filter applied
- The drillthrough page shows detailed data for the selected item (e.g., all transactions for "Customer X")
- A back button is automatically added to the drillthrough page for easy return navigation
- Cross-report drillthrough allows navigation between different PBIX files in the same workspace
- Multiple drillthrough targets can be configured for the same field (e.g., drill to "Customer Details" or "Customer Transactions")
Best practice: Use drillthrough for summary-to-detail navigation patterns. Executives see a summary dashboard and drill through to detailed operational pages for specific entities, time periods, or categories.
5. Slicers (Interactive Filters)
Slicers are visual filter controls placed directly on the report canvas. They provide the most user-friendly filtering experience because they are visible and interactive without opening the Filters pane.
- List slicer: Shows all values as a checkbox list or single-select radio buttons
- Dropdown slicer: Compact dropdown menu that conserves canvas space
- Date range slicer: Slider or calendar control for selecting date ranges
- Relative date slicer: Dynamic filters like "last 30 days" or "this quarter" that update automatically
- Numeric range slicer: Slider control for filtering by numeric ranges (e.g., revenue between $100K and $500K)
- Sync slicers: Configure a slicer to sync its selection across multiple pages for a consistent filtering experience
Best practice: Place the most commonly used filters as slicers at the top of the page. Use sync slicers for filters that should persist across pages (e.g., date range, region). Keep the Filters pane for less frequently used filters.
6. Row-Level Security (RLS) Filters
Row-level security is a special type of filter that restricts data access at the model level based on the authenticated user's identity. Unlike other filters, RLS cannot be overridden by end users.
- Defined in Power BI Desktop using DAX filter expressions on tables (e.g.,
[Region] = USERPRINCIPALNAME()) - Enforced by the Power BI Service engine, invisible to and unmodifiable by end users
- Critical for compliance: ensures users in one business unit cannot see data from another
- Can be static (hardcoded values) or dynamic (lookup the user's permissions from a security table)
- Works with both Import and DirectQuery modes
- Required for HIPAA, SOC 2, and GDPR compliance in reports containing sensitive data
Best practice: Implement dynamic RLS using a security mapping table that associates user identities with the data they are allowed to see. This is more maintainable than creating separate roles for each user or department.

Frequently Asked Questions
What is the order of filter evaluation in Power BI?
Filters are evaluated in this order: RLS filters first (model level), then report-level filters, then page-level filters, then visual-level filters, and finally user-applied slicer and filter pane selections. Each layer narrows the data further. Understanding this hierarchy is essential for debugging unexpected filter behavior and designing effective filter architectures.
Can I hide the Filters pane from end users?
Yes. In Power BI Desktop, you can hide the entire Filters pane or hide individual filter cards from end users while keeping them active. This is useful for governance filters that should not be modified (e.g., excluding test data or limiting date ranges). Provide slicers on the canvas for the filters you want users to interact with, and hide the Filters pane for a cleaner experience.
How do I make a slicer work across multiple pages?
Use the Sync Slicers feature (View > Sync slicers in Power BI Desktop). Select the slicer, then check which pages it should sync to and which pages it should be visible on. This allows a date slicer on Page 1 to filter data on Pages 2, 3, and 4 simultaneously, providing a consistent cross-page filtering experience.
What is the difference between a filter and a slicer?
Functionally, they do the same thing: restrict which data is displayed. The difference is user interface. Filters reside in the Filters pane (a side panel). Slicers are visual elements placed directly on the report canvas. Slicers are more discoverable and user-friendly because they are immediately visible. Filters are better for secondary or governance-level restrictions that should not clutter the canvas.
Can filters impact report performance?
Yes. Excessive or poorly designed filters can degrade performance. Filters on high-cardinality columns (columns with millions of unique values) are particularly expensive. Cascading filter dependencies (where one slicer selection triggers recalculation of another slicer's available values) can cause slow interactions. EPC Group optimizes filter architectures by limiting cross-filter interactions, using aggregation tables for high-cardinality scenarios, and testing filter performance with Performance Analyzer.
