Once you get going with Qlik Sense you will quickly end up with many visualizations across multiple pages, displaying connected data. To avoid redundant effort for the user, Qlik has implemented persistent filters. This means when you apply a filter anywhere in your sheet, it will also be applied anywhere else that data is referenced. This means you can easily filter an entire app in one click and not have to worry about forgetting filters or losing your train of thought.
To remove a filter, find the tab near the top of your sheet with the name of your filter and click the [x]. Just like adding the filter, this will remove it from the entire app. Check out the video below for a closer look at Qlik’s filters.
