To get started, open the filter menu by clicking the tiny filter icon in the top right corner of your project. Add your desired conditions as you would regularly do and click on "Set as default filter for "Table""
This will attach the filter to the view and will always apply it whenever the view is opened. Even after editing the conditions. In case you want to change the default filter or you want to remove it entirely simply open the filter menu of the corresponding view and select "Remove from "Table"".
Being able to set default filters is great to create a better overview of your tasks. Feel free to look at this article, that describes everything about filters.
