Hi enizard,

As you know you can have filters in any canvas in a multi-canvas project but all the canvas of the project will share the same filters.

If you don't want different canvas to have the same filter you have few options:

1. (Best in my opinion) Creating Insights and accessing them in the Narrate tab. They all can have different filters and you will see them as different pages/canvas.
2. Using the List Viz to filter. This will be independent from one canvas to another but it is not suitable for every data type
3. Using filters specific to the Viz (not the same as @ canvas level but provides big flexibility.

Hope it helps,

Juan Diego
