Why 3/4 HP?

The range of horse power (HP) offered in disposals may not seem like much but it makes a big difference in what sort of food (and how much of it) the disposal is designed to process. For instance, on the lighter side of the power spectrum, disposals with 1/3 HP are really designed to take care of the occasional food scraps and can easily dispose of soft foods, but not much else.

They are best suited for those who live alone or don’t cook much.

On the other end of the spectrum, a disposal outfitted with a whole 2 HP is generally reserved for industrial, not residential use. Between these two extremes, 1/2 HP, 3/4 HP and 1 HP are all pretty common in mid-sized homes depending on the size of the family and the use of the kitchen.

Today we’ll focus on the 3/4 HP variety because they are versatile and don’t need to be babied. A 3/4 HP disposal can usually stand up to the most common food waste and are generally reasonably priced. In terms of what to expect from a 3/4 HP disposal, think apple peels and eggshells, but not chicken bones, which makes them a great option for a lot of different homes.

What is 3/4 HP power enough for?

As mentioned at the beginning of this review, 3/4 HP is a pretty good bet for just about any basic food scraps.

Some of the things to avoid putting down a 3/4 HP disposal are bones and grizzle as well as super fibrous items like artichoke leaves. One customer reviewing the Badger 5 XP complained that an entire lemon was not ground until she cut it in half and even then the Badger had a hard time with it.

Everyone has slightly different expectations, but we don’t recommend putting entire citrus fruit into a disposal with 3/4 HP and aren’t surprised that the Badger didn’t pulverize the lemon. The idea with disposals is to cut back on food waste that is otherwise difficult and messy to dispose of, not to have a mechanical garbage can installed in your kitchen sink. Keep in mind that if you run cold water for 20 seconds after the food goes down the disposal, and feed the canister of your disposal carefully and slowly, you shouldn’t have any problem with these models grinding fruit and veggie peels, eggshells, meat, apple cores, and even small fish bones.

Again, we don’t recommend putting chicken bones or dense, fibrous animal tissue like grizzle or whole fruits and veggies down the disposal. If it is easy to toss into the trash can, then go ahead and toss it instead of putting it into the disposal.

When in doubt, throw it out.

That said, these are tough machines that often last longer than 10 years. Especially with a disposal that has a 3/4 HP motor, don’t feel like you have to handle it with kid gloves and don’t be afraid to use it. After all, that is what it’s there for.

Other Features that Matter

Some other features we think are important are as follows:

  1. Trusted brand
  2. Exemplary performance
  3. Easy installation
  4. Low noise level

1. Brand

You may notice that our list of favorite disposals tend to include a pretty limited number of brands that have stood the test of time. Brand name is an important factor to consider for a number of reasons. The brands in this and others of our lists are all established companies who have been in the industry for some time. In the case of Waste King, as mentioned, the company has been around for 50 years. Moen, for over 60 and InSinkerator has been making disposals since 1927.

When shopping for a disposal, if you begin your search with a handful of companies that have proven themselves, you have essentially mitigated a lot of the guess work from the process.

2. Performance

After you have settled on a good brand, finding a product with an excellent performance rating is your next step.

Taking a look at a record of how a certain disposal has performed for others – and in a variety of circumstances – can help determine if it will be right for you.

“Performance” should include longevity, durability, warranty, and customer service which all contribute to the product functioning as it should.

3. Ease of Installation

When it comes to something like a garbage disposal which is relatively small and inexpensive, the ease with which it can be installed is another important factor to think about.

There are some things best left to professionals with specific training (installing HVAC or putting on a new roof) and some things that require virtually no training, like changing a light bulb or a battery in a smoke alarm.

A garbage disposal is somewhere in between.

For the  majority of people, installing one is pretty doable in a couple of hours of even less. For that reason, keeping the process straightforward and simple is a priority.

4. Low Noise Level

Lastly, a low noise level is important in a garbage disposal.

All disposals are designed to do basically one thing, so we don’t think it’s too much to ask for it to be done quietly. Especially because customers with quieter disposals are more likely to use their disposals more often.

However, this feature might be more or less important to you given your lifestyle. For instance, if you have six month old twins and live in an apartment building then you might be more obsessed with quiet than someone with three teenage sons on five acres of land.

It all depends on preference but in our experience, lower noise levels sets some disposals apart from others.


Any one of our four top picks are good options for those who want a 3/4 HP garbage disposal. And although they each have specific features unique to them, the basic quality markers of brand, performance, installation, and noise level are all accounted for.

Take your time, do some shopping around and think through what is the most important feature to you after the HP rating.

Since we’ve already cobbled together some disposals with a 3/4 HP motor, you can look at other features with the core requirement already taken care.
