The Filter 3 Fill icon shows a large rounded square containing a white number 3, with an L-shaped border along its left and bottom edges. Drawn in the solid style on a 24px grid, its bold forms and open spacing keep the symbol clear in interfaces. Use it for filter presets, third-level filtering, category controls, and data or search toolbars. It belongs to Rounded Fill - Material Symbols free set in the Google Material family.
