Whether you’re prepping your week’s worth of meals or fixing a midnight snack, chances are you’re constantly dealing with food scraps in the kitchen. This is why when waste disposal units hit the market in the 1930s, Americans never looked back. Garbage disposals work by grinding up food waste, so it can float easily down the drain and through sewage pipes to your wastewater facilities, instead of being sent to decompose in a landfill. Garbage disposals vary in power capabilities and price, and choosing one for your needs depends on how much food you and your family prepare regularly. For example our top pick, the InSinkErator Garbage Disposal, can handle large amounts of food thanks to its two-part grinding system.
Here are some of the best garbage disposals to help you narrow down your choices.
InSinkErator Evolution Compact 3/4 HP Continuous Feed Garbage Disposal with Power Cord

What We Don't Love: Power cord not pre-installed
This continuous feed garbage disposal features a 0.75-horsepower motor and stainless-steel internal grind components. The InSinkerator Evolution Compact garbage disposal is powerful enough to grind potato and carrot peels without all the noise commonly associated with garbage disposals. That noise reduction is thanks to the machine’s SoundSeal Plus technology that features multiple layers of insulation and a sink baffle, the rubber piece installed between your sink and the garbage disposal.
The InSinkErator Evolution Compact also features 2-stage grinding technology, which processes food twice to produce an ultra-fine grind that won’t clog your plumbing system. With a height of 12.1 inches, its compact design is perfect for homes with restricted space under the sink. Best of all, it’s easy to install, but you will need to purchase the power cord separately.

What to Look for in a Garbage Disposal
Types of Disposals
Garbage disposals are either continuous or batch feed. Continuous-feed garbage disposals allow you to steadily pass food into the grinder chamber. A remote switch, typically located on the wall within reach of the sink, controls the disposal. Batch-feed disposals only operate when the drain cover is in place, and the grinder is powered on. You can not add waste to the grinding chamber unless the cover is removed and the grinder is powered off. Batch grinders are a little less convenient, but present more safety advantages versus continuous batch disposal.
Horsepower and Size
Most residential garbage disposals are 0.33, 0.5, 0.75, or 1 horsepower with the greater the horsepower, the stronger its grinding capabilities. Higher horsepower grinders are more robust and last longer. However, not all homes need powerful garbage disposals. For small families that do not prepare a lot of food, 0.33-horsepower disposal is sufficient for their needs. Large families that cook frequently need more powerful disposal. The size of the grinder depends on the size of the motor. In general, larger motors will have larger grinding chambers.
Disposers will offer up to three different grinding stages. With 1-stage, food is ground once before passing through drain pipes with water. A 2-stage disposal unit grinds food in twice to achieve a finer grind, decreasing the chances for clogs or jams. Lastly, a 3-stage unit provides the finest grind possible with no worry of clogs or jams.
All garbage disposals will make noise, but some are louder than others. Disposals that feature insulation around the motor will be quieter and are often more expensive. Some models offer removable sound baffles that help to reduce noise. Alternatively, you can purchase them separately to fit some garbage disposal models.
Do you ever need to clean inside a garbage disposal?
Definitely! "You'd be surprised how much food gunk gets stuck on the rubber gasket of the sink disposal," says Cortney Black, owner of Holliston Handy in Holliston, Massachusetts. "My two favorite ways to clean the disposal (and sharpen the blades) are a handful of ice cubes and two small slices of lemon. While the water is running, turn on the disposal for 10-20 seconds. It freshens the disposal and cleans the gasket. My recent favorite is garbage disposal tablets that foam and clean the inside of the disposal. They are recommended to be used once a month."
What foods should you not put down your garbage disposal?
In general, only a small bit of food should ever be put in one at a time. "Any foods that expand are the worst to put down a disposal, such as rice and pasta, especially if they have not been cooked," Black says. "Anything sinewy, such as meats, also can get stuck. It's best to toss out or compost larger pieces of food and use the disposal sparingly for longevity."
