Best Budget: Waste King L-111 Garbage Disposal with Power Cord
2-year protection plan
Not great for extensive use
Generally, lower horsepower means lower cost when it comes to garbage disposals. The 0.33 horsepower unit from Waste King offers homeowners the chance to purchase a quality garbage disposal without breaking the bank. It has an EZ mount and power cord for easy installation and a two-year protection plan in case you have any issues.
The lower horsepower does mean that this garbage disposal won’t be able to handle as many large or tough jobs, so this is an ideal choice for occasional use. If you plan on running your disposal after most meals or meal prep, opting for a higher horsepower unit might be worth the higher cost.

Best Splurge: InSinkErator Evolution Prestige Continuous Feed Noise Insulation Garbage Disposal
Power cord not included
A couple of standout features make the high-end InSinkErator Evolution Prestige garbage disposal worth the cost: Its high horsepower can tackle just about any disposal job with an ultra-quiet performance. It also has a large capacity of 40 ounces, which is almost double some of the other garbage disposals on our list.
You will need to purchase a power cord separately if required, which is an additional cost for an already pricey garbage disposal. The other option is to hard-wire the unit, but you will need some electrical know-how to do that yourself.

What to Look for in a Garbage Disposal
Garbage disposals can come in batch feed options or continuous feed options. Batch feed disposals are less common and require a special magnetic piece to be in place before the garbage disposal will operate. Continuous feed disposals are functional and only require that you flip a power switch. Batch feed models are great when you want to make sure that nothing accidentally goes through the garbage disposal. Continuous feed models, which we recommend, are very popular for residential kitchens.
Garbage disposals come in a variety of horsepower, with the majority coming in at 0.5 or 0.75 horsepower. These will both work for most households. Low horsepower models can be rated at 0.33 horsepower, but you should be aware of the limitations of these garbage disposals when it comes to grinding up larger pieces of food. Extra high horsepower disposals (those of 1 horsepower) are most commonly found in commercial kitchens and will be more than most home chefs need.
“A 0.5 or 0.75 horsepower garbage disposal should work for most needs,” says plumbing installation expert Bill Richmond of BR Plumbers. “For most users, it’s best to spend money on other features like a quiet disposal rather than high horsepower that they don’t need.”
The garbage disposal chamber can be made of a strong corrosion-resistant polymer, galvanized steel, or stainless steel. All are made to work with the wear and tear of running a garbage disposal. It’s also important to know what the blade is made of to ensure that it holds up. These are often made of stainless steel.
Your specific sink setup may dictate what type of installation you need for your garbage disposal. Start by mounting the actual disposal under your sink. Many come with a 3-bolt mounting assembly that makes it easy to change out in the future. You will also need to set up the plumbing. Fortunately, most garbage disposals come with everything that you need. If you have an electrical outlet below your sink, look for a garbage disposal with a cord. Sometimes you can purchase a cord separately, but that will add to the overall cost. It is more common to have garbage disposals hard-wired. While it is not a difficult installation, it’s always best to work with a professional electrician if you are not experienced with electrical work.
Some garbage disposals have special mechanisms that prevent larger food particles from jamming the device. These can help ensure that the garbage disposal continues to work properly, lasts longer, and prevents issues from developing with your plumbing. If you have a septic system, it is very important to get a garbage disposal that will keep your system clear and functional.
Garbage disposals can be quite loud, especially those with high-power motors. That’s why many include sound insulation or noise reduction. Choosing a garbage disposal with noise reduction technology can lower the noise of your garbage disposal so that you can even hold a conversation next to the sink while the disposal is running.
What can and cannot go into a garbage disposal?
Generally, all food waste can go into the garbage disposal. This includes soft and leafy foods such as strawberry tops and leftover salad greens. For higher horsepower models, this can also include hard food waste, such as bones. A few things to avoid putting down the disposal include fibrous vegetables like celery, coffee grounds, egg shells, fruit pits, and any grease. It’s always best to read your garbage disposal’s user manual to find out what foods it can handle.
How do you unclog a garbage disposal?
Minor clogs can be broken down using a combination of baking soda and vinegar. Pour baking soda down the disposal and follow it with white vinegar until it begins to foam. Let it foam for 20-30 minutes, which will dissolve the clog. Run hot water to wash any residue away and run the disposal to make sure it is operating properly.
For stubborn clogs, a plunger can help dislodge any large particles. You may also need to physically disconnect the disposal and remove any build-up in the unit itself or in the plumbing. Always make sure to unplug the disposal or turn off the power to the breaker, if hard-wired. If you are still unable to unclog the disposal, call a plumber to see if there is a larger issue that may be covered under your garbage disposal’s warranty. “It’s really best to call a plumber when you’re having issues,” says Richmond. “That last thing that you want is to keep running your disposal and to cause more damage.”
How do you clean a garbage disposal?
To clean a garbage disposal, start by cleaning the splash guard with dish soap. You may be able to run it through the dishwasher to get a thorough clean. Put a few ice cubes and lemon or orange slices into your garbage disposal to remove any food build-up and get a fresh citrus scent. You can also use a mixture of baking soda and vinegar to clear up any clogs that may be impacting the performance of your garbage disposal or causing odors.
