Create a new extrude feature based on the import.

Select the face of the part to start your sketch and convert entity while this face is selected. This will give you a perimeter sketch that has all the facets that you want to get rid of .

Then on each faceted area, window all the facet segments and use the sketch command 'fit spline' to replace all the facets with a single approximate spline curve.

Once you're done with that, extrude up to the opposite face of the part, don't forget to un-check 'merge result'.

Finally, 'delete body' on the faceted body and you're left with the repaired part.

'delete face' is also sometimes pretty good for getting rid of small patch surfaces or slivers of geometry that can be difficult to get rid of with cuts or extrudes.
