Evolution Essential®

The Evolution Essential® featuring Multigrind technology does what standard food waste disposers cannot, handles far more volume, and makes far less racket -- a perfect solution for a wide variety of kitchens.

Our powerful multigrind 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.

Food waste disposers provide an environmentally responsible alternative to transporting food waste to landfills.  And they can help reduce greenhouse gas emissions.  At capable wastewater treatment plants, food waste can be converted to biosolids and used as fertilizer.  Capable plants can also capture methane gas and recycle it as an energy source.  (Check the plant in your area.) Learn more about disposers and the environment.

What's more, if you've never owned a food waste disposer, you're in for a pleasant surprise. InSinkErator® disposers are economical to operate: in fact, they're among the least expensive installed kitchen appliances.

Rated 4.7 out of 5�by 258 reviewers.
Rated 5 out of 5�by It's a Hoss This is my 3rd insinkerator in 30 yrs. The first 2 my wife could plug up in a heartbeat. They were the smaller models. We have had this one a few mo. now and try as she may, not once. Not even celery or chicken skins. January 13, 2014
Rated 5 out of 5�by Easy Installation, excellent product Our old insinkerator was getting very noisy after 20+ years, replaced iwth a new insinlkerator. Very easy to install, good instructions. Having used the new insinkerator for over a year I anm happy with the product, but more inmportantly, my wife is very happy! Food goes down quickly, even tough gristly meat and it makes quick work of things like watermellon rinds and corn cobs. Most important is how quiet it is. Excellent Product and I highly recommend it!! . January 8, 2014
Rated 5 out of 5�by Excellent product, quiet and efficient. If the product continues to perform thru its life cycle as it is now it is an exceptional disposal. The only unknown is if it will last as long as it should. December 31, 2013
Rated 2 out of 5�by noisy after minimal use Upon initial installation this product was great. As we began to use it the sound level grew to what now is an annoying vibration. December 30, 2013
Rated 5 out of 5�by Quiet yet powerful!! Great addition to my new kitchen!! Quiet and effective ... Easy to use and no issues. December 30, 2013
Rated 5 out of 5�by This product has a very quiet motor I never had a disposal before and purchased it for a kitchen remodel. Many of my friends and family who have used it when we are cooking together in the kitchen have remarked how quiet it is, compared to their builders grade disposal. I have an open kitchen to my family room and it never disturbs anyone watching television because it is that quiet. I would definitely recommend this product. I also had it professionally installed.
