1. InSinkErator ProCCPlus Pro Series 3/4 HP


Quietest Garbage DisposalThe list begins with InSinkErator ProCCPlus Pro Series with ¾ HP. This particular model isn’t the cheapest one on the market, but is definitely one of the quietest out there. With the Sound Seal Plus technology, the ProCCPlus is at least 60% quieter than most garbage disposals.

Huge 40-Ounce Stainless Steel Grind Chamber and Grind Components handle more volume than most disposers. However, you must consider the available space under your sink, because this fella is quite huge, the dimensions are 15 x 15 x 21 in and the weight is 20.2 pounds.

2. InSinkErator Evolution Excel 1.0 HP

nSinkErator Evolution Excel 1.0 HPAnother beast from the InSinkErator brand, Evolution Excel 1.0 HP delivers massive performance with stony silence. Due to famous SoundSeal technology, the disposal is very quiet despite its great 1.0 Horse-power. Actually, after looking on the internet for hours and checking user reviews, Evolution Excel is probably the quietest 1.0 HP (if not quietest in general) garbage disposal on the market as of now (2018).

Other features that are worth mentioning are 40 oz. Stainless steel grind chamber, MultiGrind technology and 7-years In-Home Limited Warranty. The dimensions are 12 x 12 x 13 inches and the weight is 25.5 lbs.

3. Waste King L-8000 1.0 HP

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. 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.

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. Moen’s dimensions are 7.5 x 7.5 x 16 inches and the weight is 13 lbs.

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.

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.  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.
