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 treatment facilities, instead of creating methane gas as it decomposes 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.
Here are some of the best garbage disposals to help you narrow down your choices.

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.
