What to Know
1/3 HP: Light Duty
Soft food scraps only. Jams frequently on anything tougher. Best for single-person households or rentals. $60-100.
1/2 HP: Standard
The minimum for most households. Handles most food scraps including fruit rinds and small bones. Jams occasionally on fibrous foods. $80-150.
3/4 HP and 1 HP: Heavy Duty
- 3/4 HP handles everything a household kitchen produces.
- 1 HP provides fastest grinding and virtually zero jams.
