The 6 Best Garbage Disposals to Buy in 2018

Shop for the best garbage disposals for your kitchen sink

Tired of uneaten food scraps that end up stinking up the house or attracting pests while they sit in the trash can? A convenient garbage disposal can grind food waste into pieces so tiny that they can go right down the drain of your kitchen sink instead.

Most garbage disposals are continuous-feed, which means they can keep running as you drop in new food waste. They’re convenient, but they may pose a safety risk to curious kids who stick their fingers down the drain. They also typically require a...MORE wall-mounted power switch. The other kind of garbage disposals, batch-feed models, must be loaded up with food scraps before users activate them with a magnetized stopper. They’re safer for use around kids and can usually be powered by a simple outlet and power cord, but they may not be as convenient for families with a lot of food waste.

Whatever type of garbage disposal you pick, experts warn against expecting them to grind up very fibrous food waste like celery, banana peels or corn husks. Steer clear of putting pasta and rice down the disposal, too, since these foods can expand and block pipes. Grease is another obvious no-no, as are any non-food items.

Need recommendations? Here are six of the best garbage disposals for residential use:

    Experts give this InSinkErator very good marks for speed, fineness of grind, and ability to cut through tough vegetable...MORE scraps.

Several owners say it was easy enough to install without a professional and has plenty of power for all kinds of food waste.
