Good

No other disposer can match its raw power. Extremely quiet and efficient. Includes 7-year warranty (in home).

Powerful, quiet, and undoubtedly durable.

All internals are galvanized, and the machine is known to be extremely durable.

2,800 rpm. Extremely durable stainless steel impellers won't rust and are designed to reduce jamming to a minimum.

Whisper-quiet. Quality is assured by KitchenAid's reputation and some InSinkErator components.

Bad

More expensive than other units, but its durability and top-of-the-line materials may could save you money in the long run.

Although it boasts "EZ mount installation," most people will still need a professional for power connection.

Struggles to break down bones & hard materials like corn husks.

Doesn't fit certain cast iron sink types. (Other Waste Kings do.)

The collar that keeps the noise in also makes it a bit difficult to feed in waste.

Bottom Line

The best garbage disposal available today. No other matches it in terms of quality, performance, and durability.

Adequate for single people or couples, but you may want a larger machine for larger households.

A budget model that isn't as well-insulated as higher-end models. As such, it tends to be noisy.

The best value for your money. Popular, powerful. and quiet w/a lifetime guarantee.

A big, powerful unit with a dependable manufacturer and parts contributor.

Best Garbage Disposals

Putting your waste down the sink rather than in your bin is convenient and good for the environment - but which garbage disposers handle all you can throw at them and come back for more?

The very best garbage disposals should sit quietly out of sight, have the features necessary to perform efficiently when called on, and should offer trouble-free durability. The five machines that most successfully fulfill those criteria are:

Considerations

Size & Power

The size of a garbage disposal can effect how easy it is to fit into your kitchen and how much waste it can handle. The amount of power that the machine has also has a huge impact on how much garbage it can process.

Feed & Grinder

There are two distinct types of feed and potentially numerous stages of grind, each of which improves efficiency. Our ratings tell you which garbage disposal is best equipped to handle the job that you need done.

Features & Functions

Does the garbage disposal unit have a cover? Auto-reverse to clear jams? A cable so you don't have to hardwire it? We examine all the extras that make your appliance easier to live with.

Price

We never review sub-standard machinery, but we do try to be aware of a variety of household budgets. Our selection of five top garbage disposals shows this.

Considerations

Size & Power

General Electric GFC320V

Our first appliance, the General Electric GFC320V, is a relatively small unit at a fraction over 12 inches tall. One of the most important measurements with garbage disposals is the size of the grind chamber which, in this case, is 26.5 ounces. That doesn't mean you can throw that amount of food waste in it all at once, but it gives a good indication of its intended capacity when you compare it with other models. Power, at 1/3 hp, is at the lower end of the scale, but you have to bear in mind that the General Electric is a light-duty machine. The vast majority of owners we surveyed were very happy with its performance.

InSinkErator Badger 1

InSinkErator is one of the biggest names in garbage disposals. The InSinkErator Badger 1 is at the lower end of their range, but that should in no way be considered a criticism. At 26 ounces, the machine's capacity is almost the same as that of the GE, and the power from the Dura-Drive induction motor is identical at 1/3 horsepower. The unit is a little taller at 14 inches, but that's unlikely to be enough to present any installation problems.

Waste King L-8000 Legend Series

Although very nearly the same height as the InSinkErator above (just 0.2 inches taller), the Waste King L-8000 is larger in girth. We were unable to find a precise figure for its capacity, but given that it shares some components with other Waste Kings, it's safe to assume it's around 33.5 ounces. Motor power we do know, and it's a big jump up at 1 horsepower. That's about the maximum you will ever find on household waste disposals.

KitchenAid Continuous Feed Garbage Disposal

KitchenAid is known for a wide variety of appliances. The KitchenAid Continuous Feed Garbage Disposal is also 14 inches tall but even larger in circumference than the Waste King. Hence the 40-ounce capacity. Power is just a little lower at 3/4 hp, though in use, that difference is negligible.

InSinkErator Evolution Excel

Our final choice is another InSinkErator: the much larger and more powerful InSinkErator Evolution Excel Household Garbage Disposer. Similar in size to the KitchenAid, it shares that machine's 40-ounce capacity. This time, though, there's a full 1 horsepower motor, thus giving the most potent combination here. There's absolutely no other disposal system that can match this machine's raw power.

The one-horsepower motor of the Waste King L-8000 will grind just about anything.
Considerations

Feed & Grinder

Garbage disposal units come with one of two kinds of feed: batch or continuous. With the first, you simply fill your machine and  turn it on. With the second, you turn it on, run some water, and drop waste in. Batch disposers have minor safety advantages (it's more difficult to accidentally drop cutlery in there that would break the blades), but they are inconvenient with large amounts of waste. Continuous machines are more flexible, more hygienic (there's no temptation to leave food rather than run it half full), and usually cheaper when comparing like for like. For these reason, all of our top five garbage disposals are continuous feed models.

The General Electric GFC320V has dual-swivel, stainless steel blades with two pre-cutters meant to prevent jamming. Blade speed is 2,500 rpm. When combined with the 1/3-hp motor, that's adequate for most vegetable matter. 

In many ways, the InSinkErator Badger 1 is similar to the General Electric. Power and capacities give it a similar performance, although the InSinkErator runs slightly slower at 1,725 rpm. All internals are galvanized, and the machine is known to be extremely durable. Both products are highly rated by owners, though useful life won't be helped if either machine is continually fed bones or hard materials like corn husks.

Waste King L-8000 Legend Series

With its powerful motor, you might expect the Waste King L-8000 to be a bit of a beast. In fact, it is. It runs at 2,800 rpm and features durable stainless steel impellers that will never rust and are designed to reduce jamming to a minimum. The manufacturer claims it will "grind just about anything," and we found a few owners who happily admitted to throwing chicken bones in it without any problems. Indeed, one zealous user suggested it would "grind up an oak tree!"

The KitchenAid Garbage Disposer features what they call "Multigrind Technology," a two-stage system claimed to be able to tackle all kinds of food waste. Some of the internal components are actually produced by InSinkErator, so you have their reputation to add to that of KitchenAid. It certainly seems to have numerous satisfied owners, including one who tested it by feeding it ice cubes. It passed, but that practice is not recommended.

InSinkErator Evolution Excel

As if to confirm that it shares some internals, the InSinkErator Evolution Excel Household Garbage Disposal also has "Multigrind Technology." In this case, however, that technology is of the three-stage variety. The parts involved all have impressive names: GrindShear Ring, Tri-Action Lug system, and Undercutter Disk. They're equally impressive in action. Put just about anything in the top, and what comes out the other end is practically liquid. For some reason, potato peels are notorious for clogging waste disposers, so one owner tried a whole one (it's remarkable the abuse people want to give these machines). His quote? "It disappeared."

The InsinkErator Evolution will take remarkable abuse day after day.

Features & Functions

General Electric GFC320V

When providing an electricity supply for your garbage disposer, you can use an ordinary household socket. But the cable is an extra cost, and most are designed to be direct-wired (so you'll need someone qualified to do the job). Although the General Electric GFC320V boasts "EZ mount installation," most people will still need a professional for power connection. Sound insulation is adequate, and there's a splash guard, stainless steel sink flange, and stopper to help prevent things from falling in by accident when not in use. You can also connect your dishwasher drain to keep under-sink plumbing to a minimum. The General Electric also has overload protection which is manually reset and seems to be a very well-regarded feature by owners.

InSinkErator Badger 1

Like the GE, the InSinkErator Badger 1 is normally direct-wired, although a power cord accessory kit is available. Another similarity is an easy mounting set-up, called "Quick Lock." Again, like the GE, its internals are made of galvanized steel. This InSinkErator is definitely their budget model and isn't as well-insulated as the higher-end models, so it tends to be a little noisy.

Waste King L-8000 Legend Series

The main difference between the General Electric, the InsinkErator, and the Waste King L-8000 (apart from the aforementioned size and power) is the internal components. All of the Waste King's internals are stainless steel. Galvanizing prevents things from rusting, but it's a coating that is subject to wear. Stainless steel, on the other hand, is the material itself and so cannot rust. Waste King supports this product with a lifetime in-home warranty. There's also an easy-fit system, splash guard, and a power cord supplied. One owner commented that this model doesn't fit certain cast iron sink types. (Other Waste King garbage disposals do.) Potential buyers should check first before purchasing.

KitchenAid Continuous Feed Garbage Disposal

The KitchenAid Garbage Disposal is another model that doesn't include a power cord, but that can't really be considered a negative given that it's so common among the top machines. Some internals are stainless steel, but others are simply called "corrosion resistant." The five-year warranty reflects this. The auto-reverse is a great feature should you get a jam (although most owners find this extremely unlikely), and it includes the usual quick-mount system, dishwasher drain connection, and overload protection. The vast majority of owners we surveyed were keen to point out that in use, the KitchenAid is extremely quiet.

InSinkErator Evolution Excel

In many ways, you could look at the InSinkErator Evolution Excel Garbage Disposal as the perfect combination of all of the features listed above. It's quiet, thanks in part to anti-vibration technology as well as a huge amount of insulation. It has many stainless steel components, along with a seven-year in-home warranty. It has "Quick-Lock" mounting, a stainless steel stopper, and a sensor that will automatically increase motor torque if there's any danger of a jam. It also has a useful "Do's and Dont's" card, although many owners have said that they throw in almost every type of food item, including chicken and rib bones, without a problem.

Considerations

Price

General Electric GFC320V

The General Electric GFC320V Food Waste Disposer is currently on sale for $70. The main criticism of garbage disposals of this size is the power provided and the materials used in construction. It's really a question of what you want the unit for. Given its price, it should prove adequate for single people or couples, but if you're looking to dispose of materials for a household of four or greater, you may want a larger machine.

InSinkErator Badger 1

The InSinkErator Badger 1 Food Waste Disposer is similar to the General Electric in a lot of ways. Currently on offer for $75, it's tough to choose between them. On the one hand, you have InSinkErator's reputation for garbage disposals. Despite plastic components and occasional reports of leaks with this particular model, they've been known to last 10 years. On the other hand, many consider the Badger 1 a bit loud and prefer the GFC320V's more subdued presence.

Waste King L-8000 Legend Series

List price on the Waste King L-8000 Legend Series Garbage Disposal is $94. It's a popular, powerful, quiet machine. Given the lifetime warranty, it's undoubtedly durable, too. Customer ratings are consistently high, and perhaps even more tellingly, every single owner we surveyed had nothing but good things to say about this machine.

KitchenAid Continuous Feed Garbage Disposal

At the moment, the KitchenAid Continuous Feed Garbage Disposal is on sale for $238. It's a big, powerful unit, and quality should be assured both by KitchenAid's reputation and the use of some InSinkErator components. A couple of owners did complain that the collar that keeps the noise in also makes it a bit difficult to feed in waste. These owners said that that they would have preferred a wider opening.

InSinkErator Evolution Excel

The InSinkErator Evolution Excel Household Garbage Disposer costs $324. That's a substantial investment, but judging by the many satisfied owners of this product, there's little doubt that it will do what you expect it to. In fact, its durability and top-of-the-line materials may also end up saving you money in the long run.

The durability and top-of-the-line materials of the InSinkErator Evolution Excel may end up saving you money in the long run.

Best of the Best

There isn't a poor machine in our selection of top five garbate disposals. The General Electric GFC320V and InSinkErator Badger 1 both do what you would expect, and they do it well, but you can't have something for nothing. If you need a family machine, you need something bigger.

Which brings us to the Waste King, KitchenAid, and InSinkErator Evolution. Again, all are good machines. But when we really dig deep, there's no question that the best machine on the market today is the InSinkErator Evolution Excel Household Garbage Disposer.

This is such an attractive unit, it's almost seems a shame to hide it under the sink! While looks don't tell you anything about its abilities, they do give a clue to the thought and quality that went into its design and construction. InSinkErator ise the world's largest manufacturer of waste disposals, and the experience and reputation are evidenced here. Owners are delighted with how quiet it is and how efficiently it functions. Comments like "perfect," and "the last waste disposal you will ever buy," are common among users. When it comes to a review of the best garbage disposals, what more can you say?

The InSinkErator Evolution Excel Household Garbage Disposer is "perfect," according to many owners.

Best Bang for your Buck

The garbage disposal that's the Best Bang for Your Buck will, to some extent, depend on your point of view. If you're on a tight budget or live on your own, the General Electric GFC320V or InSinkErator Badger 1 will do a decent job, as long as you use them sensibly.

However, for just a bit more money, you can have the machine that we've rated as the overall best value: the Waste King L-8000 Legend Series Garbage Disposal.

You get an awful lot for not an awful lot of money. There's a full one- horsepower output. There are stainless steel impellers for long life. There's a lifetime warranty on mechanical parts and against corrosion. Even the superb InSinkErator Evolution Excel doesn't go that far.

In our research for this review, we found that several people who had previously owned an InSinkErator Badger 1 all preferred the Waste King. The stopper has prevented several from accidentally dropping cutlery inside. Although some parts are plastic, construction quality was consistently praised.

In general, people really love this machine. One owner, having fed it leftover chicken drumsticks, buffalo wings, and edamame shells, called it "unstoppable."
