They come with different horse-power, sizes and shapes and noise levels. But the most powerful models are often extremely noisy, so we will take a look at the quietest garbage disposals on the market.

The noise level is something you should definitely consider. But which garbage disposal is the quietest? To what should you compare the noise if this is going to be your first disposal? Should you trust sound-proof technology or simply look at the decibel level?

Well, fear not! To spare you time and effort searching for the quietest garbage disposal, I’ve put together a list of 5 quietest garbage disposal units on the market. Here you can compare horsepower, size, weight and decibel level of each model.

Waste King L-8000 1.0 HPThe Waste King L-8000 is one of the best models out there in general, but what is often left out is the fact that it’s also one of the quietest models out there. While it does not have the SoundSeal technology of InSinkErator, it does come with the 1 HP, 2800 RPM permanent magnet motor that is sound-insulated.

The L-8000 also includes all-stainless steel grind components; lifetime limited In-home warranty and pre-installed power cord. Not to mention that it’s far cheaper compared to the quietest models of InSinkErator. The size is 8.5 x 8.5 x 16 inches and its weight is 11.94 pounds.

4. Moen GX50C 1/2 HP (GX Series)

Moen GX50C 1/2 HPWhile Moen does not have as wide selection of garbage disposal units as other brands, GX50C is definitely worth mentioning in regard to noise. It operates at 2600 RPM, ½ HP with the high-speed Vortex permanent magnet motor and due to the SoundSHIELD sound insulation technology; it’s less noisy than other standard garbage disposals with similar parameters and definitely belongs among other quiet garbage disposals.

Other features worth mentioning are removable splashguard, polished stainless steels drain stopper and drain elbow and mounting assembly. If you need a good quality ½ HP garbage disposal without the extra noise and don’t want to spend a lot of money, definitely go for GX50C.

5. InSinkErator Evolution Septic Assist ¾ HP

InSinkErator-Evolution Septic Assist 3/4 HPI know, it may look like I’m favoring the InSinkErator brand, but since we are reviewing the quietest garbage disposals on the market, InSinkErator offers the widest range of disposal units in this regard. Evolution Septic Assist is no different and it deserves a place on our list.

As with other two InSinkErators mentioned in this article, Evolution Septic Assist comes with the SoundSeal technology as well, but this particular model also includes septic garbage disposal Bio-Charge cartridge technology to break down food wastes while controlling odor.

¾ Horse-power Dura-Drive motor takes care of every food chunk you put in with the 2-stage grind operation. I just love the fact that InSinkErator can make powerful, yet quiet garbage disposals. While the installation is easy, this model does not come with a power cord, so you need to purchase it separately. Product’s dimensions are 14 x 11 x 16 inches and the weight is 22.3 pounds.

IE Septic Assist with its greatly-designed Sound-seal technology peaks at 65 dB while during standard run, the noise output is only 45 dB, thus deserving a spot on our list.
