Filters are a useful feature that allows Jira Admins to execute common searches without having to recreate the same search query each time.

With Optimizer for Jira Cloud you can see at glance all Filters available in Jira, alongside their Owner, Subscriptions, Favorites, and the underlying JQL query.

This allows you identify and remove unused Filters based on their number of subscriptions as well as keep the matching JQL query updated.
