What horsepower garbage disposal do I need?

For a one- or two-person household, a 1/3 to 1/2 HP unit like the InSinkErator Badger 1 or Badger 5 handles everyday scraps. Larger families or homes that grind harder food waste tend to step up to 3/4 HP (Badger 5XP, KRAUS WasteGuard) or 1 HP (InSinkErator Evolution 1HP) for fewer jams and faster grinding, based on how verified-purchase reviewers describe their use.
