To find the best garbage disposal for your home, consider your budget and the kind of food waste you’ll be discarding. The two primary types of garbage disposals are batch feed and continuous feed disposals.

Before you shop, look under your sink to see how much room you have to add or replace a disposal. Not all models will fit under all sinks, but small disposals are available for small spaces. 

Batch feed models operate in batches and run only when a stopper is placed over the disposal opening and a switch is turned on. Because they must be used with a stopper, they’re a good choice for households with children who might be tempted to put their hands or the wrong kinds of items into the disposal. The stopper also helps prevent items from accidentally falling into the machine. You must put the food waste into a batch feed disposal and put the stopper in place before turning it on.

Batch feed garbage disposals are safer to use than continuous feed models. They are usually more expensive than continuous feed disposals.

What is a continuous feed garbage disposal? As the name suggests, a continuous feed model turns on with the flick of a switch and runs until it is turned off. It allows you to add food waste while the disposal is running. Some models offer auto-reverse functions, advanced grinding features and special circuitry to help eliminate jams. 

Some units also come with splashguards to help prevent items from splashing back out while you are adding food waste. If you have small children, be safe and watch them if you have a continuous feed disposal. Don't allow them to put their hands or anything else into the unstoppered opening, which can cause serious injuries.

In general, continuous feed garbage disposals are easier to use and less expensive than batch feed models.

Garbage disposals come in different sizes and with different features. Motor sizes vary from 1/3 HP to one HP. The higher the HP, the better the garbage disposal will run. Food waste will be ground into finer particles and you'll have fewer jams.

1/3 HP Motors

Basic disposal models have 1/3 HP motors. These are typically at the lower end of the price scale. They can be a good choice for small households that use them infrequently, or for short-term or limited use in vacation homes, but they don’t usually hold up to frequent or extended use. The best garbage disposal for a small household, or where meals are prepared infrequently, may be a basic model.

1/2 to 3/4 HP Motors

Most manufacturers recommend at least a 1/2 HP garbage disposal motor. Because disposals with these motors are smaller than disposals with one HP motors, they can fit into relatively small spaces under your sink. Models with 1/2 HP or less should be run with plenty of cold water to help the food waste go through. 

Manufacturers usually recommend 3/4 HP models for most homes. These usually offer more features, such as stainless steel components, and tend to last longer than models with less powerful motors. They’re also larger, so be sure you have room under your sink to accommodate one before you buy. 

One HP Motors

Models with one HP motors also require extra room under your sink and are at the higher end of the price range. However, they have a larger capacity for food waste and seldom jam.

Households with two or more people, or where meals are prepared often, may find the best garbage disposal for their needs is a 1/2 to one HP model. Higher HP is also recommended for those who want a model that can handle difficult-to-grind food waste, such as fibrous materials or bones. 

Tip: As a rule of thumb, models with higher HP motors have better sound insulation and run more quietly than basic models.

The answer to how long a garbage disposal lasts depends on how often you use it, what kind of food debris you put in it and whether or not you use and maintain it properly. On average, a garbage disposal can last about twelve years.  

To help your garbage disposal last longer, avoid running hot water when using it. Also, avoid grinding fibrous materials such as celery stalks or corn husks in a basic disposal. Basic disposals are designed to handle normal amounts of food waste such as fruit and vegetable peels, soft food scraps and small bones. Premium disposals can handle larger jobs.

If you need to repair your disposal, read your manufacturer's directions so you will know what kind of garbage disposal parts to buy.

Your manufacturer's instructions will also tell you what your garbage disposal can and cannot handle, whether you are on public sewer or a septic tank system.

Be safe, and never reach into the disposal while it's in use. Always disconnect the power before reaching into it.

• To maintain your garbage disposal and help it last longer, run cold water in it before, during and after operation. 
• Grind small bones to scour the grinding chamber, and use disposal cleaner, deodorizer or citrus peels to freshen the disposal. 
• Run the disposal each time you put food in it to reduce corrosion from acidic foods.
• Remove silverware and other items from the sink before using the garbage disposal.
