Purge Unused Filters (Revit pyRevit Tool)

Find every unused view filter and clear it, or rename your filters in bulk.

View filters multiply across templates and views until the list is unmanageable. This pyRevit tool audits each filter by how many views and templates reference it, then lets you delete the unused ones or batch-rename any selection with a live preview.

What's inside

• One pyRevit button: Purge Filters
• An audit dialog showing each filter's view count, template count, and where it is used
• Unused filters highlighted and sorted first
• Batch rename with prefix, suffix, or find-and-replace, with a live preview
• Safe deletion that removes a filter from its views and templates first

Who this is for

• BIM managers enforcing a filter naming standard
• BIM professionals cleaning inherited models full of stray filters
• Revit users transitioning into BIM who want to see filter usage before deleting

Requirements

• Autodesk Revit 2021 or newer
• pyRevit installed (free, from pyrevitlabs.io)
• Runs in a single confirmable, undoable Revit transaction

What you'll get faster

The manual audit of which filters are safe to remove, plus the tedium of renaming filters one at a time to match a standard.
