Over the past 79 years InSinkErator has been known for building the world's best food waste disposers. Today, the new Evolution Series disposers represent the highest standard in performance. Simply put, they are the best grinding, quietest line of disposers we have ever made. Our powerful food waste disposers are the right choice when replacing an existing unit or designing a brand-new kitchen. You can choose between five Evolution models, including Evolution Septic Assist, designed specifically for homes with septic systems.

With an InSinkErator food waste disposer in your kitchen, chicken bones, fruit rinds, coffee grounds and more can go right in the sink -- where they're virtually liquefied to safely flow into your sewage system or septic tank. You'll enjoy a cleaner food preparation area, and less bagged garbage cluttering your home.

Featuring MultiGrind and SoundSeal technologies, Evolution Series disposers grind more with less noise.
