Quiet Garbage Disposal Units For A Silent Kitchen 2019

Quiet Garbage Disposal Units For A Silent Kitchen 2019

Garbage disposals are very useful and indispensible in modern kitchens.

But they are quite noisy as well.

So it is no wonder people are looking for quiet garbage disposals. Kudos to manufacturers, they are quick to catch on.

But before I give you the list of these garbage disposal units, may I ask you a question?

How quiet can a garbage disposal be?

You will be amazed to know that a well-insulated disposer makes only as little sound as water flowing down your sink drain.

A normal garbage disposal produces a sound of approximately 80 decibels (same as that of a lawnmower). The quietest disposals produce only a decibel level ranging from 25db to 45db (A normal conversation between two people is 60 dB).

To give you an idea of the sound levels of some popular garbage disposals here is a video;

The noise made by a disposer mostly depends on the level of insulation it has, premium products tend to have better insulation than cheaper ones.

Also, the sound produced by a disposer is not just from its motor running and grinding but is from the vibrations it causes on the sink. The better fit it is with the sink the lower will be the vibrations and hence the noise.

During my extensive research, I found not one but 7 disposers which run really quiet (which you can easily find with my Disposal Finder Tool). Of course, the levels of noise they make are different but they are the quietest of all.

1. InSinkErator Evolution Excel

Quietness level – ‘Ultra-quiet

Though only by a small margin this InSinkErator disposer is the quietest on my list.

It is also the best garbage disposal I came across.

Evolution Excel comes with top class insulation for its grinding chamber. Its 3-bolt mounting and other premium level connection accessories reduce vibrations to none. All these make this disposal the quietest of all.

As you might have guessed this is a premium model, and so it comes with a large array of features.

It is powered by a 1HP motor which runs at a speed of 1725RPM.

A quick overview of its features include;

  • 3-stage grinding system
  • LeakGuard liner
  • SoundSeall technology
  • Stainless steel build
  • QuickLock easy installation
  • Jam-sensors
  • Auto-Reverse grinding system
  • 7-year warranty

I am not going into much details of this disposal as I have already done a detailed review here.

2. Waste King A1SPC Knight

Quietness level – ‘Ultra-quiet

Though silver in color this disposer reminds me of Batman, most probably it is the name; Knight.

While all other Waste King disposals lack in design, this one is an eye-candy.

This disposal uses ‘exclusive silencer’ technology which makes it one of the quietest.

In fact, this is as quiet as the Evolution Excel, which puts this in the Ultra-quiet category.

Definitely, Waste King made this model to compete with the top end InSinkErator models; especially ‘Evolution Excel’.

They made sure that this product doesn’t lack behind in anything, it is powered by a 1HP high-speed motor which runs at 2700RPM whose performance is at par with those having multi-stage grinding. It has top-notch built quality with stainless steel grinding components and a corrosion resistant grinding chamber.

One great advantage of this model is its price tag, it is much cheaper than its competitors. What more, it comes with a lifetime limited warranty eclipsing all competition.

3. InSinkErator Cover Control Plus Evolution

Quietness level – ‘Ultra-quiet

This is quietest batch feed disposal. The only other such type of disposal mentioned in this list is ‘InSinkErator Essential’.

Its operation is ultra-quiet which is the same as that of the ‘Excel’ model and that of the Waste King Knight. It is priced at the premium end.

Without a doubt, this is a premium model and comes with all features of the top InSinkErator models.

Its operation is quiet, it has a chamber capacity of 40oz, is powered by a 3/4HP motor and has a 2-stage grinding system.

In addition it also has a magnetic collar which helps to prevent any metallic items from accidently falling into the disposal and damaging it.

InSinkErator cover control plus evolution is covered under a warranty of 7-years. You can read about this disposal here in detail.

4. InSinkErator Evolution Essential

Quietness level – ‘Quieter

Though not as quiet as the Evolution Excel this product has excellent noise insulation thanks to the Sound Seal technology.

In addition, it uses 3-bolt mounting which reduces vibrations.

And this is a Batch feed type disposal.

This top-end InSinkErator model comes with lots of features and premium build quality.

It runs on a 3/4Hp dura-drive motor (all InSinkErator models use Dura-drive induction motors) at a speed 1750 RPM. Though slightly underpowered than the Evolution Excel model it has the same chamber capacity which is 40oz.

It has a 2 stage grinding system ie, food wastes are ground twice which makes them very granular. This makes it easier for the drainage system, and also reduces any chances of jams and clogs.

The Evolution Essential comes with a warranty of 6 years.

If you like to know more about this disposal here is a detailed review.

5. InSinkErator Essential XTR

Quietness level – ‘Quieter

This one is as quiet as the above model and is similar too with the exception that this is a continuous feed type disposal.

Like its predecessor, it makes use of ‘Sound Seal’ technology. It operates quietly, the noise insulation is not the very best but still, it is great.

Though silent it uses a 3/4 HP motor and a 2 stage grinding system to grind food wastes to a pulp. It is pricier than the Waste King models, I should say that unless you have some specific reasons any of the above-mentioned disposals are good.

6. InSinkErator Evolution Compact

Quietness level – ‘Quiet

Evolution Compact got its name because it targets the small garbage disposal section of the market.

It uses SoundSeal technology, and a 3-bolt mounting system to reduce noise and vibrations.

But it is a tad noisier than the Essential model, which makes Evolution Compact the 4th best quiet disposal unit in the world.

As you know this is an InSinkErator product. In fact, 5 out of the 7 disposals I have chosen here are made by InSinkErator. The company clearly focus on being the best in this market segment.

As the name indicates, it has a compact design but still can accommodate 34.6oz of food wastes.

It is powered by a 3/4 HP motor which is the same as that of the ‘Essential’ model.

In terms of features, it stands at par with Evolution Essential and Essential XTR. All of them share common features including multi-stage grinding and Quick-Lock installation.

It also has a 4 year limited warranty.

For more details checkout my review of Evolution Compact.

7. Waste King L-3200

Quietness level – ‘Quiet

The L-3200 is a very popular product from Waste King.

It is not as quiet as the ‘Evolution Excel’, but its sound insulation comes at par with that of the ‘Evolution Compact’ model.

It is powered by a 3/HP permanent magnet type motor running at 2700RPM (all Waste King disposers use permanent magnet type high-speed motors.). It has only 1-stage grinding but the grind efficiently is none the less.

One thing I like about the Waste King models is that they all come with a power cord and a removable splash guard which makes it easy to remove and clean them.

This model has a limited warranty of 8 years, the stainless steel components and the corrosion resistant grinding chamber by no doubt give the confidence that this product will last forever.

While the build quality may not be at par with any of the InSinkErator models mentioned above this disposal is more economical.

If you are looking for a premium quality disposer which gives the best value for money this is what you are looking for.

And here is my detailed review if you need any more info.


Quiet garbage disposals are getting popular but generally speaking they are also pricey. It is because this feature comes only with top-end models. Like I said before a normal disposer operates at a sound level of 80dB, it is not unbearable, and you use it for only a short period of time. So quiet garbage disposals are not indispensable but just optional.
