The Best Garbage Disposals of 2024

We’ve spent hours researching expert advice and the science behind garbage disposal units. With that in mind, as well as looking at real customer reviews, we have the seven best garbage disposal units to recommend.

Here are the units that will make your cooking and cleaning experience easier!

InSinkErator Garbage Disposal Evolution Excel

Best Quiet Garbage Disposal

The InSinkErator is a one-of-a-kind garbage disposal, especially regarding noise.

In fact, it’s the quietest garbage disposal unit currently on the market. It has advanced noise-reducing, insulated SoundSeal Technology. So when you run this unit, you’ll hardly notice it.

This disposal runs at only 45 decibels which is somewhere between the sound of a refrigerator and a light rainfall.

What We Like

Powerful and Durable Construction

Although it’s quiet, it’s powerful. It has one HP, so it’s perfect for larger families or people who dispose of a lot of food waste.

The 40-ounce grind chamber with a galvanized steel system can grind even the toughest food scraps. Plus, it has a LeakGuard Liner for extra durability.

Fast and Clean Usability

Make cleanup quick and easy with this garbage disposal unit. It also ensures your kitchen is clean and it leaves no mess behind.

It quickly disposes of tough ingredients, even bones, without making much noise. So you can enjoy your meal and the cleanup process more than ever.

Easy Installation

It’s no problem to install the InSinkErator. The quick lock mount makes it super easy to install, especially if you previously had an InSinkErator model.

Once you’re with InSinkErator, you’re with them for life since they make the switching process so easy. Just twist off the old and twist on the new.

Three-Stage MultiGrind Technology

This superior technology helps the unit grind the toughest food without jamming or clogging. It breaks the food down into tiny particles so it can be drained away. This includes melon rinds and chicken bones — items you usually shouldn’t put in a garbage disposal!

What We Don't Like

Rubber Opening

Many customers have complaints about the rubber opening. It helps keep the unit quiet, but it can be frustrating.

It doesn’t let the water drain from the sink quickly, so it builds up and dirties your sink. Plus, it doesn’t have super strong suction to pull down the water and floating food scraps.

Take Note

Don’t manually push down the food scraps since this is a continual feed unit, and you could injure yourself.

High Price Point

This is one of the most expensive garbage disposal units that we found. If you’re on a budget, the price of this unit might make you scream.

User Experience

For those in search of a powerful and quiet garbage disposal, the InSinkErator Evolution Excel is a fantastic choice. Having replaced my previous Waste King model, I immediately noticed the significant noise reduction in comparison, which is especially useful in an open concept home or for late-night dishwashing. The 1 HP motor makes quick work of grinding up table scraps, and the USA-made product also boasts reliable support and service. Installation was a breeze, taking around 60 minutes for a reasonably handy person to complete. The auto-reverse feature helps prevent clogs and jams, and the stainless steel housing adds a touch of elegance.

InSinkErator Garbage Disposal + Air Switch

Best Continuous Feed Garbage Disposal

While most of our recommendations are continuous feed, the InSinkErator Garbage Disposal and Air Switch is by far one of the best.

The innovative design features a ¾ HP Dura-Drive Induction Motor and 2-Stage Multigrind Technology. It also has SoundSeal Technology to produce low noise levels.

This is the smart choice if you have a large family or a lot of food scraps. It guarantees fast and efficient garbage disposal.

What We Like

Exclusive Dura-Drive Motor

With this unit, you get a high-quality and outstanding motor: Dura-Drive. It operates at ¾ HP, which is exclusive to InSinkErator.

Dura-Drive is long-lasting and utilizes high grinding force to tackle most food scraps, even tough or thick ingredients. The 2-stage Multi Grind Technology aids this feature by grinding food into extremely small particles.

Easy Swap Installation

If you’ve previously had an InSinkErator product installed, it’s easy to switch it out for this new one. The Quick Lock feature is compatible with all InSinkErator products.

Simply twist off the old unit and twist on the new unit. It also has an included garbage disposal air switch that can be installed on your countertop. You can easily clean it while wiping down your countertops.

SoundSeal Technology

This is a super quiet unit, using SoundSeal Technology to keep the noise levels to a minimum. The advanced noise reduction makes this the quietest unit from InSinkErator after the Evolution Excel and Compact unit. Customers say that when this is on, you don’t even know it’s running.

Super Durable Construction

The price point on InSinkErator disposals is so high partly due to the durable components. This unit is made from stainless steel alongside a LeakGuard Liner, which assures durability. The air switch is made from satin nickel, adding to the robust construction.

What We Don't Like

Small and Narrow Gasket

The gasket on this unit is small, with a narrow opening. This helps to reduce sound, but it makes it difficult for all food scraps to get into the unit. It also means it doesn’t drain well, which can dirty your sink.

Always be careful when pushing food into the unit, and ensure the disposal is switched off before doing this. Otherwise, you can risk injury.

American Standard ASD-1250 Torque Master

Best High-Capacity Garbage Disposal

If you want something with ultimate power — especially for large families — look no further than the American Standard Torque Master. With the highest horsepower on our list, this unit comes in at 1.25 HP.

This is incredibly powerful, especially for people with lots of food waste, tough ingredients to dispose of, or more than eight people living in the house.

What We Like

Powerful High-Speed Motor

The high-speed motor boasts 1.25 HP and 2800 RPM. This unit can quickly shred and grind up most ingredients — even chicken bones and fruit peels — in just a few seconds.

We also love that it’s quiet, which is exactly what you need with lots of people living in the house. While the kids are sleeping, you can turn this on without waking anyone up. It has an Insulated Sound Shell which aids its low noise level.

Bio-Shield Prevents Odors

This disposer comes with a Bio-Shield. Inside, an antimicrobial agent protection gets rid of garbage disposal smell caused by bacterial growth.

So you can toss in any food — coffee, vegetables, and small bones — without worrying about bacteria or microorganism growth. Plus, it’s safe to use with septic tanks.

Silver Magnetic Guard Captures Metal Objects

Included with this unit is a Silver Guard Magnet. It’s attached under the sink around the throat of the disposer. It captures most metal objects, so they don’t enter the disposer chamber.

This feature prevents damage to cutlery, metal objects, and the disposer. That way, you can save money on repairs and increase the unit’s lifespan.

Budget-Friendly Price Point

At less than the average unit cost, this one is a hit with customers on a budget. Plus, it’s covered by a 10-year warranty, so you know you’ll get your money’s worth if anything goes wrong.

What We Don't Like

Rubber Splash Guard

It’s important to note the rubber splash guard. It creates a good seal around the drain, but the flaps warp easily, which is both unaesthetic and inconvenient.

Feels Cheaply Made

A few customers described that the unit felt it was cheaply made. It was a little tricky to install, quite bulky, and required regular maintenance.

Community Feedback

I've recently started using the American Standard Torque Master and I must say, it has been a fantastic addition to my kitchen, particularly for my large family. Its powerful high-speed motor and 1.5 HP makes it incredibly efficient in disposing of food waste and tough ingredients, perfect for a household of more than eight people. I appreciate the added features such as the Bio-Shield to prevent odors and the Silver Magnetic Guard that captures metal objects. The only downside is that the rubber splash guard feels a bit cheaply made, but given its budget-friendly price point, I think it's a minor issue.

Moen GXS75C Host Series 3/4 HP

Best No-Jam Garbage Disposal

There’s nothing more annoying than when a garbage disposal jams all the time. That totally defeats the point!

With the Moen GXS75C, that’s one problem you don’t have to worry about. It has a high ¾ horsepower. Combined with the 2700 RPM, it rarely ever jams.

The high-performance permanent magnet motor is specifically designed to reduce jams since it finely grates up the food.

What We Like

Powerful Unit for Most families

This powerful unit has a ¾ HP — the recommended size for most families, between three and six people. This will be the best size if you have average or moderate food waste.

Compact To Fit Under Most Sinks

This unit’s sleek and compact design makes it suitable for most homes. It’s lightweight and frees up space under your sink. Another bonus: it has a Universal Xpress Mount. Simply position, twist and lock it into place.

Quality Vortex Motor

This unit has a high-quality Vortex motor, which makes it so powerful. It has exceptional grinding power to tackle most ingredients.

The permanent magnet motor fires up at full speed as soon as it’s switched on. Plus, this motor helps to reduce jams.

Exclusive 360-Degree Clean Rinse

Garbage disposal units can get smelly since they deal with a lot of food waste. But this unit has a unique feature to rinse away food scraps more thoroughly, which can lead to fewer odors.

What We Don't Like

Noisy Unit

Despite the Sound Shield insulation — this is a noisy unit. It has a loud click noise, and while it’s operating, customers say it’s far from quiet. If you want something with minimal noise or live in an apartment building, this might not be the unit for you.

Not for Tough Food Waste

While some of our other recommendations can grind up fruit rinds and animal bones, this one is more basic. You shouldn’t pass through bones, stringy vegetables, or other tough ingredients — it just can’t handle it.

First-Hand Impression

I recently replaced my old garbage disposal with this Moen product and I'm quite satisfied with its performance. The installation process had a few challenges, such as needing an extra part for hardwiring, but once it was installed, it worked like a charm. This disposal is significantly quieter than my previous one and handles food scraps like apples and peppers with ease. The included tool for fixing jams is a great addition, as it's easy to use and conveniently stored under the sink.

Moen GXB75C Host Series

Best Batch-Feed Garbage Disposal

For ensured safety, many people choose a batch-feed garbage disposal.

The Moen GXB75C only works once you’ve engaged and locked the batch feed stopper. This prevents unwanted items from getting in while the disposer is in use.

Sure, it processes a little at a time, so it does take longer than a continuous feeder. But we like that you control what’s in there and what’s happening.

What We Like

Powerful 2700 RPM Motor

The Moen GXB75C has ¾ HP, which is recommended for families, even if you have a lot of dinner guests. It can handle most scraps of food and leftovers, of course, feeding it in using small batches. It grinds at 2700 RPM, which does the job efficiently and reduces the chance of jamming.

SoundSHIELD Technology Minimizes Noise

This is one of our quieter options. While the noise level is still noticeable, it’s not too loud. It uses SoundSHIELD sound-deadening insulation to reduce noise levels without compromising the unit’s power.

Easy To Install

This unit is easy to install, especially if you are replacing an old garbage disposal. This unit fits most existing setups, even from other brands. It also comes with a pre-installed power cord, so you don’t have to go out of your way to buy one.

10-Year Warranty

With a lengthy 10-year warranty, you can rest assured you’re getting your money’s worth. This unit is on the more expensive side, but with eight year’s reassurance, you can sit back, relax and let your food grind!

What We Don't Like

No Protective Gasket

Unfortunately, there’s no protective gasket with this unit. So if something falls in, it’s in there. Of course, you can work on getting it out before you start the unit, but it would be much more convenient if there were a separate gasket to prevent this in the first place.

Could Be Quieter

While this is a quiet unit, thanks to the SoundSHIELD technology, it’s not as silent as our other recommendations. If you want something that’s barely noticeable, this unit might disappoint.

User Experience

I've had this product installed for a short time and so far, I'm very pleased with its performance. The Moen garbage disposal is quieter than my previous model and handles small bits of leftover food and produce scraps well. Although the installation process had a few challenges, it was made easier thanks to the help of a skilled friend. An added bonus is the larger, easy-to-use tool for fixing jams, which is inserted into the top of the unit rather than the bottom.

Waste King Legend Series 1 HP

Best Warranty

Looking for extra reassurance when investing in a garbage disposal?

The Waste King Legend Series 1 HP has a lifetime warranty against mechanical and corrosion issues. If it malfunctions or fails to work — they will replace or repair it free of charge.

This is one of the best warranties in the business of garbage disposals. You can rest assured that you’re getting your money’s worth.

What We Like

High-Speed 2800 RPM Motor

This is a workhorse in the kitchen with a high horsepower of one and 2800 RPM. It’s compact but powerful. It keeps your kitchen sink clean and tackles everyday food scraps in a matter of seconds.

With this energy-efficient grinder, you never have to worry about jams or blockage again.

Quiet Humming Sound

You might think that the high horsepower and RPM means this disposal will be so loud that you’ll get a headache. Well, you thought wrong! This unit is super quiet, with customers comparing it to the sound of someone humming.

Easy To Clean the Unit

It’s important to clean your garbage disposal unit regularly. Thankfully, this one is a breeze to clean since the splash guard is removable. This allows you to get into the unit and clean it well.

Easy To Install

You’ll love how quick and easy this garbage disposal unit is to install. The EZ mount makes it quick to install, and the removable splashback makes for easy cleaning.

It also has a pre-installed electrical cord. So you don’t need any electrical experience to be able to slot this thing under your sink and get it working.

What We Don't Like

Plastic Parts

Although this is a durable product, it still has many plastic parts that don’t hold up as well as steel. For example, the grinder barrel is made with plastic on the top ⅔ of the barrel.

The drain flange is mostly plastic. It’s not super secure, and it breaks more easily than if it were made of steel.

However, all the grinding components are made from stainless steel.

Too Big for Tight Spaces

This unit is on the larger end of garbage disposals, so it’s not good for tight places or if you’re limited on kitchen space. The dimensions are 8.5 x 8.5 x 16 inches, so it’s much larger than average units. Make sure you have the space for this before purchasing.

Personal Perspective

This product has been a great addition to my kitchen, replacing my old InSinkErator 333. The installation process was simple, taking me only 30 minutes to an hour to complete. I've noticed that this garbage disposal is significantly quieter than my previous one, making it much more pleasant to use. One downside is its height, which is around 18.5 inches, making it taller than most garbage disposals. However, the lifetime warranty makes up for this minor inconvenience.

Waste King L-111 Garbage Disposal

Best Budget Pick

The Waste King L-111 is a popular product, especially if you’re on a budget. At this friendly price point, you still get a high-quality garbage disposal that is easy to install and has a continuous feed.

Because of the price, it does have a ⅓ HP motor, which isn’t the strongest.

However, if you use it properly, minimize your food scraps, and ideally, live on your own, this is an excellent choice!

What We Like

Compact and Lightweight

If you’re tight on space, this is a good option. It’s very compact (5.25 x 5.25 x 12.75 inches), so it should fit under most sinks. It’s also lightweight (7.5 pounds), making it easy to install.

The twist and lock design makes this handy little unit quick to install. Finally, a power cord is included.

Continuous Feed Unit

Many families prefer a continuous feed, like what the Waste King has to offer. A wall switch activates it, and it quickly grinds food waste continuously while it’s turned on. The blades can grind up most kitchen waste in a matter of seconds.

Durable Construction

This garbage disposal is made with a high-quality, corrosion-proof glass-filled nylon grind chamber. It has other stainless steel components which are reliable, long-lasting, and don’t rust.

Splash Guard for Easy Cleaning

This unit has a splash guard, which makes cleaning the disposal a total breeze. It’s also removable, making it easy to collect items you dropped in the unit. Plus, it’s replaceable, so if it becomes damaged, you can simply replace this one element rather than the whole unit.

What We Don't Like

Minimal Horsepower

Because this is on the lower end of the HP scale — being at ⅓ — don’t expect incredible power. It can’t handle a lot of food or stubborn scraps like fruit and vegetable peels or bones from meat.

Hard To Unclog Jams

Although not many customers complain about jams inside the machine, when there is a jam — it can be hard to remove. The opening is tough to access, so unclogging the unit is difficult, and you can’t see what you’re doing. Sadly, there isn’t much manufacturer guidance on how to fix jams.

This Waste King L-8000 garbage disposal unit was a great purchase for me. The installation was super easy and it only took me around 30 minutes to an hour to complete. It's significantly quieter than my old InSinkErator 333 and comes with a lifetime warranty. The only downside is that it's quite tall, so it takes up more space under the sink.

What Do Garbage Disposals Do?

A garbage disposal is an electrical unit installed between a sink drain and a trap. When it’s on, a spinning disc or plate turns quickly in a grinding chamber, chopping and shredding the food into tiny pieces so they can be washed away down the pipes.

Are Garbage Disposals Good for the Environment?

It depends. Many areas have a wastewater system that is committed to turning food waste into energy. However, the food waste could be going into the sewer systems or directly to landfill, which contributes to waste. We recommend checking with your local area to see what the situation is.

Overall, the best way to deal with food waste is to minimize it. This can be done through meal planning, prepping, or donating scraps. You can also compost food waste which is an eco-friendly option.

Do You Need a Garbage Disposal?

Even if you don’t have a lot of food waste or manage to compost most of your food — it’s still a good idea to have a garbage disposal. Little bits of rice, pasta, and vegetables can easily fall down the sink while you’re straining them. Or perhaps a family member always dumps out leftover cereal as they rush out the door.

Having a garbage disposal means your sink is less likely to get clogged. Just turn on the garbage disposal, which will shred up the food waste into tiny pieces, saving you money on a plumber!

Types of Garbage Disposal Systems

There are two types of garbage disposal systems: batch feed and continuous feed.

Batch Feed

Batch feed garbage disposals run in batches.

First, there is a cover that goes over the disposal entrance. You need to manually put food in there before turning it on.

This is great because it ensures premium safety. No accidental finger injuries or automatic starting if you accidentally drop something special — like jewelry — into the sink. However, it does take longer, and these garbage disposals can be more expensive.

Pros

  • These models are safe since the stopper needs to be placed properly.
  • No risk of injury.
  • Great for small amounts of food waste.
  • Works well on kitchen island counters.
  • You have control over the power and water usage.
  • Easy to install.
  • They generally operate more quietly.

Cons

  • They are more expensive than continuous feed models.
  • It takes much longer to grind food up.
  • Not best for large amounts of food waste.
  • Replacement covers cost a bit of money.
  • They take up more space beneath the sink.
  • They clog more easily.

Continuous Feed

Continuous feed garbage disposals are more common. They keep running from when you turn them on until you switch them off again.

Many brands make continuous feed models, meaning you should find something within your budget. They can also handle more food, which is great for bigger families. The main drawbacks are that they aren’t as safe as batch feed garbage disposals and they use more water.

Pros

  • Available in a range of budgets.
  • Best for large amounts of food waste.
  • Great for more populated households.
  • Reduced risk of clogging.
  • This model is always on, so it helps you keep your kitchen clean as you cook.

Cons

  • Since the drain is always open and the motor running, these models aren’t as safe.
  • They use more water and energy.
  • It will try to grind anything that enters it, including silverware or jewelry.

How To Choose the Best Garbage Disposals

Let’s look at the top details to consider when choosing a new garbage disposal unit.

Size

Garbage disposals come in a variety of sizes.

Will Any Garbage Disposal Fit?

Garbage disposal units are not usually universal. So, you will need to find one that fits your sink. It’s best to get a plumber to investigate this.

This will involve measuring the connection size from the garbage disposal unit to the drain. Since there are many options available, you’ll find one that fits your sink.

What Size Garbage Disposal Is Best?

Ensure that the option you choose will fit underneath your sink. Always check the dimension of the unit against the space you have available. Measure the length, width, and height to ensure compatibility.

You should also check the connection size of the unit to ensure it can fit the sink drain. If it doesn’t fit, you can choose a different unit or buy an adaptor to connect the pieces.

Local Regulations

Before you buy, contact your local area or building authority to check that garbage disposal units are allowed in your community. Not all areas have sewage systems that are compatible with municipal waste. This leads to plumbing issues as it can easily clog the pipes.

If this is already an issue, we don’t recommend a garbage disposal.

Family Needs and Horsepower

Choose your unit based on how many people are in your household. That will determine the horsepower (HP) to go for.

  • ⅓ HP — one to two people.
  • ½ HP — two people.
  • ¾ HP — three to five people.
  • ⅝ HP — three to six people.
  • 1 HP — five to eight people or commercial properties.
  • 2 HP — eight people or more, plus bigger commercial properties.

If you generate a lot or little food waste, go up or down a size to suit those needs.

Something To Note

⅓ HP units are the cheapest but the least effective. We recommend a 1.25 HP motor today, which is the most powerful on our list.

Budget

Garbage disposals aren’t cheap, but they come at various prices. Our research found the price ranges from about $60 to $400, with the average being around $150.

If you want more bang for your buck, check out the warranty to get a rough idea of how long the unit should last.

Noise Levels

Garbage disposals can be super quiet or rather loud. The higher the HP, the more likely it is to be quiet because of the extra insulation.

If you’re bothered by loud noises, look at the features. It might have sound-quieting technology, extra insulation, or coated blades.

Ease of Installation

Most garbage disposals will come with instructions for relatively easy installation. This varies depending on the brand.

Do I Need a Plumber To Install a Garbage Disposal?

You can do it yourself. But if this isn’t the job for you, you can definitely hire a plumber.

Warranty

Garbage disposals come with a range of warranty periods, but it’s important to consider this factor. Our recommendations range from having a two-year warranty up to 20 years.

How Long Does a Garbage Disposal Last?

Your garbage disposal should last around 10 years, but hopefully, it lasts up to about 15 (1). However, warranty covers can range from one to 20 years.

How Much Does a Plumber Charge To Replace a Garbage Disposal?

Depending on your area, the price generally varies between $180 and $380 (2). Keep in mind this does not include the price of the garbage disposal unit.


FAQs

Can You Run the Garbage Disposal While the Dishwasher Is On?

The dishwasher and garbage disposal most likely share the same drainage pipes. You can get clogged pipes if there are remaining food particles in the garbage disposal before using the dishwasher.

However, you definitely can run the garbage disposal while the dishwasher is on. Just be cautious about how much you put down the disposal. Generally, the pipes are already pumping away waste, so go ahead and use it!

What Causes Garbage Disposals To Leak?

Here are a few reasons why your garbage disposal might be leaking:

  • There is a loose seal somewhere. This is most likely on the sink flange. It can be fixed with some plumber’s putty.
  • The internal seal in the garbage disposal unit is broken, which can happen over time.
  • The drain lines have become disconnected. You’ll need to tighten or reseal the connections.

What Can I Do With My Old Garbage Disposal?

If it still works, you can donate it. If it doesn’t work, you can recycle it according to manufacturer instructions and your local area’s guidelines.

You could even upcycle it into a kind of blender. Deep clean it, put it over a bucket and put fruit and vegetables through it to get nice, pressed juice.

Can You Sharpen Garbage Disposal Blades?

Many garbage disposals don’t use blades — instead, they have a grinding chamber. But to clean and sharpen the blades or to clean out a grinding chamber, try this method:

  1. Add salt and ice: Throw a handful of salt and 10 ice cubes into the garbage disposal with running cold water.
  2. Run the unit: Run the garbage disposal for one minute. The ice cubes will help to sharpen the blades. The salt will scrub the grinding chamber.
  3. Flush: Flush with cold water for 15 seconds to drain away all remaining debris.

Why Does My Garbage Disposal Smell Like Sewer?

If this is the case, get it checked out as soon as possible. It’s likely that something has happened within the system, and it can be a health hazard.

Some sewer gases can be toxic and irritable, especially to people with compromised immune systems (3). Call a plumber or professional garbage disposal service immediately.
