What To Consider When Buying the Best Garbage Disposal

Before you buy a garbage disposer, it's beneficial you consider how its specifications can affect its performance. Many factors go into choosing the best disposer. For instance, how many people are in your household and if you have small children who will grab anything within reach; such factors will help you decide whether to purchase a continuous feed disposer or a batch feed garbage disposer.

The size of your family also determines the power and size of the unit -based on the amount of food processed in a day. In addition, will you install the disposer yourself or hire a pro? Answering these questions will help you decide which disposer is best for you. Here are a few factors to consider when buying the best disposer:

Grinding Technology

A disposer is compromised of a motor and an internal canister known as the grinding chamber that is equipped with sharp blades spinning at top speeds when the disposer is powered down/turned off. The garbage disposer’s base is punctured to allow ground food wastes to flow from the chamber and down the drainpipe.

Disposers are divided into two different types: the continuous feed and the batch feed unit.

The continuous feed garbage disposer runs constantly when turned on, which allows you to throw large food scraps into the grind chambers. Today many disposers on the market are continuous feed and their prices range depending on their power and quality. The prime drawback to continuous feed disposers is the possibility of someone’s hands slipping in the grinder which can cause injuries.

The batch feed garbage disposer pulverizes small food wastes and is much safer for your family and curious children. Before a batch feed disposer operates there must be a stopper in place. Safety is the prime draw for this type of disposer, but they are generally more expensive than continuous feed.

If you buy the batch feed, you can only run one load of food batches at a time. The size of the grinding chamber will differ depending on the model but will generally pulverize 2 to 4 cups of food scraps at a time.


The more powerful a disposer is, the more efficiently it will pulverize food wastes. Just like many appliances that use motors, the power that a disposer generates is measured in horsepower (HP), an energy unit that was once compared to real horses.

1/3 horsepower: These are the least expensive disposers you'll find, but they are prone to clogging when they grind fibrous foods like carrots. Unless you're planning on using a disposer occasionally and grinding soft foods only, we'd advise you to buy a more powerful one.

1/2 horsepower: A 1/2 horsepower disposer is ideal for midsize households and will grind most food scraps; just make sure you don't overstuff it to ensure it doesn't jam.

3/4 horsepower: Now we can start talking about real power! A 3/4 horsepower is powerful enough to grind its way through fibrous foods with no problem and is ideal for households with a large family and considerable food scraps.

1.0 to 1.2 horsepower: These powerhouses make everything look easy, they virtually grind all food scraps you throw into it, which includes watermelon rinds.


The greater the horsepower, the larger the motor, which most of the time will require you to increase the unit’s size too. While the size will differ according to the brand, the smallest horsepower disposers range from 6 to 7 inches in width and 9 to 12 inches in height. Set side by side with a powerful one disposer like the 1.0 horsepower disposer, it can go up to 13 inches in width, and 18 inches in height.

The one time the size of the unit will make a difference is when your kitchen space is limited. If you own a water filtering system; for instance, the reverse osmosis unit, you might have less room space for a large system. Ensure you take measurements of the space under your sink and match it up with the garbage disposer you’re fascinated with.

Grinding Chamber Material

Most of the time the disposer is exposed to water and garbage, so it is recommended you buy a disposer that has a durable grinding chamber.

The grinding chamber can be made from different materials like stainless steel, pot metal, plastic, and galvanized steel. All materials make good grinding chambers but just like many appliances, each material has its pros and cons.

Stainless steel is the most standard. Even though it is more upfront, it will last longer than other materials – you might never have to replace the disposer. Moreover, the chamber doesn’t rust, and the stainless-steel grind parts are the easiest for cleaning.

Plastic is second as it doesn’t wear off. But in time the components will crack when the plastic starts drying out. Even with that con, those components will last for long before they crack; you should get years of service from the disposer before replacement. It is easy to clean since it lacks corrosion.

Pot metal is mostly plated or painted. With time the coating will scrape away, and the metal beneath will rust and later be covered in a white powder-like material. Although they might end up looking second-class, the thickness of the components means they are durable and can serve you for decades.

Galvanized steel has a galvanized protective coating that will begin to wear down as soon as the garbage disposer starts working. In less than one year, the grinding chamber will begin to rust, and after a few years, the components might fail.

Direct Vs Plug-in

Most disposers are designed to be directly wired into the electrical system, so many don't have power cords that can be plugged into an outlet. However, certain models are built with cords and plugs that can be attached to an outlet under the kitchen sink.

Garbage disposers that don't come with plugs can be transformed into plug-in models with the purchase of optional plug-in cords which you will buy separately.

A disposer that comes with a cord to plug into an outlet is the easiest to install, but a dangling cord underneath the sink may interfere with stored cleaners and other items which can remove the plug from the outlet.

Many disposals that are professionally installed are directly wired, meaning the wires connected are inside the junction box in the wall, which minimizes the risk of moisture interfering with the wiring.

A plug-in model can be damaged when a water leak runs down the wall, which could result in a short out and flip the circuit breaker, even though the possibility of such an incident occurring is minimal.

Although the choice of installing the disposer through direct wiring or plug-in is normally left up to the owner to decide, it is best to check in with your local building authority just in case there are regulations set up in your community.

Connecting your disposer to a non-plug unit is simple if you have experience in wiring, and instructions that come with both the disposer and the cord kit. Unlike the non-plug unit, hard wiring your disposer into the home’s electrical system is a bit complex and should be left to those with experience in that department.

Frequently Asked Questions

How does a garbage disposer work?

Garbage disposers are attached beneath the kitchen sink to lay hold of the solid food as it goes down the drain. As soon as the food is inside the grinding chamber, you can turn on the machine and leave the rest to the machine as it grinds the food wastes into smaller pieces. These pieces will now pass through the pipes at ease instead of causing clogs.

How long can a garbage disposer last?

Many garbage disposers can live up to 10 years. If your disposer has a hard time grinding food scraps, makes excessive noise than usual, or regularly clogs, it might be time you replaced it.

How do you use a garbage disposer?

Start by turning on the water in your sink before you turn on the device (use cold water). Once you've turned on the disposer, moderately drop the food wastes down the drain. When you're done disposing of the food, power down the device and run cool water down the drain for a few seconds to flush the pipes.

Winding Up

The best garbage disposers should have at least one of these features;

In our research, we've ensured to recommend the best, easiest to install and gathered the top picks from different models. It is advised to buy disposal with a capacity that suits the number of users and the type of food waste you plan to dispose of. For fruit peels, a light garbage disposal should suit you, but for fibrous or hard food wastes, you will want a disposer with a powerful horsepower.

Apart from horsepower, you might want to decide whether you want the continuous feed or batch feed disposer. The difference between the two is that continuous feed will pulverize food scraps constantly, while batch will grind the food waste only if the sink is covered and closed off.
