Just about every filter has that on the box, however they are referring to the bacteria growing on the media eliminating ammonia and nitrite. Not actually media that will remove ammonia right out of the box.
As for carbon, it is not a big ammonia absorbing medium to my knowledge. It does help, however, remove discoloration, odors, and pollutants such as soap. It may help to a degree however I do not believe it can absorb enough to make a huge difference.
