Save filters – should we use an icon and what should it look like? [on hold]

We are adding a save filters functionality for our mobile application. When the user clicks the save filters button we keep all of the currently selected filters so he can then use the same filters in the future.

Should we use an icon to trigger this feature or not? Our first thought was the classic save disk icon but we are not sure if it is the proper icon for that use. Any advice would be appreciated.
