Check Size, Power, and Installation
-
Measure cabinet clearance
You must verify vertical and horizontal space before purchasing. Heights vary significantly, ranging from 12 inches for the InSinkErator Power Series to 17 inches for the InSinkErator SS-100. Widths also differ, with some models like the Waste King measuring 7.5 inches and others like the InSinkErator SS-100 spanning 13.6 inches. Ensure your under-sink area accommodates the specific dimensions of your chosen unit to avoid installation conflicts.
-
Choose plug-in or hardwired
Determine your electrical setup first. Some disposals, such as the Moen EXL100C, come with a pre-installed power cord for simple plug-in use. Others, like the GE Disposall GFC1020N, require hardwiring directly into your home’s electrical system. Selecting the correct type depends on whether an outlet is available under your sink or if you are prepared to handle electrical connections for a direct-wire installation.
-
Evaluate grinding stages
Look at the grinding mechanism for efficiency. The InSinkErator Evolution models use a 4-stage system to process food waste thoroughly. Other units, like the Hliay FCD-1006, feature a 6-stage assembly for enhanced reduction. Multi-stage systems generally handle tougher scraps better than single-stage designs. Check the product specifications to see how many grinding levels the motor supports for your specific waste habits.
-
Consider motor speed
RPM indicates how fast the grind plate spins. The Kraus WasteGuard models operate at 3,800 RPM for rapid processing. Most standard 1 HP units run around 2,800 RPM. Higher speeds can reduce grinding time for soft foods. Compare the RPM values in the specs to find a motor that matches your kitchen’s waste volume and your preference for quick cleanup cycles without excessive noise.
-
Check weight and material
Heavier units often indicate more durable construction. The InSinkErator SS-100 weighs 50 pounds and features a stainless steel chamber for heavy-duty use. Lighter models, like the Kraus KWD100-100MBL, weigh under 10 pounds. Consider the weight when assessing build quality and noise dampening potential. Heavier casings may offer better sound reduction, while lighter units are easier to handle during installation.
Frequently asked questions
What is the difference between continuous feed and batch feed disposals?
Continuous feed models run as long as the switch is on, allowing you to process scraps in one go. All items in this guide use continuous feed for efficiency. Batch feed models require a special stopper to activate, which adds a safety step but slows down the workflow. If you prefer speed and simplicity, continuous feed is the standard choice for most kitchens.
Do 1 HP garbage disposals work well for hard food items?
Yes, 1 HP motors provide the torque needed to crush tough items like chicken bones and fruit pits. High-speed models like the Kraus WasteGuard reach 3,800 RPM to pulverize waste quickly. Multi-stage systems, such as the InSinkErator Evolution, use multiple grinding levels to ensure even hard scraps are reduced to fine particles before entering your plumbing.
How tall are the shortest 1 HP garbage disposals?
The InSinkErator Power Series is the most compact option at 12 inches tall. It fits well in tight under-sink cabinets where space is limited. Most other 1 HP models range from 13 to 16 inches in height. You must measure your cabinet clearance before buying to ensure the unit fits vertically without hitting pipes or shelves.
Which 1 HP disposal is best for reducing noise?
The InSinkErator Evolution series uses SoundSeal acoustic insulation to dampen operational noise. The Evolution LED model also includes an illuminated odor-defense flange to help with smells. The MAX Disposer features a quiet rating and multi-stage grinding to minimize vibration. If noise is a priority, look for models with specific sound-dampening technology or stainless steel chambers.
Can I install a garbage disposal without calling an electrician?
You can install plug-in models yourself if you have an accessible outlet under your sink. Units like the Moen EXL100C and Waste King L-8000 come with pre-installed power cords. Hardwired models require direct connection to your home’s electrical system and may need a licensed professional. Always check the power type listed in the specifications before purchasing.
What is the largest capacity garbage disposal in this list?
The GE Disposall GFC1020N offers a 32-ounce capacity, which is the largest in this selection. This volume allows you to process larger amounts of waste in fewer cycles. The InSinkErator SS-100 is a heavy-duty commercial unit weighing 50 pounds, designed for high-volume use. Check the specs to find the capacity that matches your household’s waste output.
Do any 1 HP disposals include a power cord?
Several models come with pre-installed power cords for easy plug-in installation. The Moen EXL100C, Waste King L-8000, Kraus WasteGuard, and MAX Disposer all include cords. The InSinkErator Evolution with Cord also provides this convenience. If your sink cabinet lacks an outlet, these plug-in options save you the trouble of hardwiring or hiring an electrician.
