What's behind our garbage disposer Ratings?

Experts at our National Testing and Research Center tested 13 models in garbage disposers to see which ones perform best.
We look for:
  • Overall score
    Overall score is based on performance and noise, and other factors not shown in the Ratings, such as occurrences of stalling and ejecting of unground bones.
  • Speed
    We judged each model's speed of grinding beef bones and vegetable scraps. The speed of grind was based on the amount of bone that was ground in one minute of operation.
  • Fineness
    We judged each model's fineness of grinding beef bones and vegetable scraps. The fineness of grind was based on the distribution of particle size after all bones were ground to completion.
  • Vegetable scraps
    For vegetable scraps, whole celery stalks and whole potatoes were used.
  • Noise
    We judged noise as a combination of decibel readings while grinding bones and judgments of sound generated while grinding other table scraps.

Garbage disposer buying guide

Garbage disposers link the often-disparate demands of convenience and conservation by grinding up kitchen scraps and sending them down the drain to a sewage-treatment plant or septic system for decomposition. But our tests show that some grind more quickly and finely, and are better at resisting jams.

Besides eliminating messes and discouraging bugs and other pests, a garbage disposer shifts food waste from landfills to a wastewater treatment system.

That has prompted some cities to require disposers in new homes. Add in the many towns that charge by volume for waste removal, and it's easy to see why nearly half of American homes have a garbage disposer.

But some municipalities discourage residential garbage disposers because of inadequate sewer systems or water supplies. Even if your community allows disposers, using one may cost you more than you think. Some cities also worry that garbage disposers encourage homeowners to flush down fat, oil, and other greasy residue that can clog sewers.
