Best Continuous Feed Garbage Disposals Reviews

Find the best continuous garbage disposal option for your household with this detailed guided review!

by Holly Curell

One of the most convenient machines that we have in our households is the best garbage disposal. If you were to go outside of the US, you would find that many homes don’t have this handy device, meaning that you have to throw any food scraps into the garbage before cleaning your dishes.

Thankfully, we don’t have to worry about that, unless of course there is something wrong with our disposal. Most of these units are built to last for many years, but that doesn’t mean that they don’t break down eventually. When that happens you will have to replace it with something just as durable and reliable, but how do you know which one is best?

When it comes to finding a new disposal, we have compiled a list of some of the greatest models out on the market. Also, we’re going to show you what features to look for to ensure that you’re getting the best deal of Best Continuous Feed Garbage Disposals.

How to Choose The Right Continuous Feed Garbage Disposals

One thing that we should mention is that there are two primary types of garbage disposal from which you can choose. We are going to be looking at continuous feed models, which means that you can turn them on and off with a switch and they will chew through food as long as they are active. The other type of disposal you can get is batch-feed. These disposals require you to seal the system before you can turn it on, which is safer and better if you don’t go through a lot of waste in your home.

Overall, continuous models are far more ideal for most households, but it’s important that you are aware of your options.


When comparing different disposal units, you will see that some of them are quite compact while others take up quite a bit of room. The reason for the size difference is usually with regard to the motor and the grinding chamber, so if you opt for something with more power, then it will take up much more space under your sink. Thus, it’s imperative that you measure your current unit and see what limitations you might have before buying a new one. You don’t want to waste time and money purchasing a new disposal only to have it not fit correctly.

What else you should look at regarding size is the grinding chamber. The large it is, the less you have to worry about getting clogs or backups in your system as you can process more waste at one time. That being said, it’s also important to get a model with multiple grinding levels so that you can chew through food better without worrying about clogs.


As you’ll see, garbage disposals come with motors that are measured in horsepower. At first glance, it might seem like a good idea to pick the one with the most power, but that doesn’t necessarily mean that you get the best results. While having a more robust motor is important, there are a couple of other things that you should look at to make sure that you’re getting the best machine for the job. RPM is another factor that can determine the quality of grinding you get, as well as the material of the impellers. In the end, a larger motor can be a great thing, but don’t assume that it’s the only thing worth paying attention to.


As far as internal components go, you want to make sure that you’re getting high-quality materials that will last for years. For the most part, disposals will either come with galvanized or stainless steel parts, with the latter being far better than the former. We strongly advise getting a stainless steel model because it won’t rust or corrode easily, ensuring that it will last longer overall. That also means that you don’t have to replace it as regularly as you would with other units. Also, stainless impellers usually stay sharper for longer, meaning that they will chew through food much more efficiently than galvanized. The main reason to choose galvanized steel instead is that it’s more cost effective.
