I don't know of a whole house size filter that will do this at a reasonable cost. The fluoride that is added to municipal water supplies is an extremely tiny compound molecule, and passes right through carbon filters. The only filter that I know that will remove fluoride is reverse osmosis, which strips everything else out also, so minerals need to be added back.
