InSinkErator Garbage Disposals Buying Guide
Photo by Julio Lopez / PexelsInSinkErator was founded in 1927 by Racine, Wisconsin architect John Hammes, who invented the first household garbage disposal unit for his wife's kitchen. The company was acquired by Emerson Electric in 1998 and dominates the US garbage disposal market with approximately 70% market share. InSinkErator manufactures all products in Racine, Wisconsin. The Badger series covers entry-level continuous feed disposals; the Evolution series covers premium multi-grind, quieter units.
HP Ratings: What Size Disposal Do You Need?
Badger 1 (1/3 HP): entry-level, suited for single-person households with light food waste (soft vegetables, small scraps). Limited on fibrous vegetables (celery, artichokes) and tough waste. Badger 5 (1/2 HP): standard for most households -- handles typical daily food waste including chicken bones and harder vegetable scraps. Most popular InSinkErator model. Evolution Advanced (3/4 HP): premium tier for families or households with high food waste volume -- handles fruit pits, small bones, and harder waste that overloads smaller motors. For a household of 4+ or a kitchen with frequent entertaining: the 3/4 HP Evolution is the right choice.
MultiGrind Technology: Three-Stage Grinding
Evolution series disposals use MultiGrind three-stage grinding -- food waste passes through three grind stages rather than one, producing finer particles that flush more easily through residential drain pipes. The practical benefit: reduced drain clogs compared to single-stage grinders, particularly important for older homes with smaller diameter drain pipes. The Badger series uses single-stage grinding -- adequate for soft waste but more prone to drain accumulation over time with frequent fibrous vegetable waste.
SoundSeal Insulation
Evolution series disposals use SoundSeal technology -- a combination of anti-vibration connections, an insulated motor shell, and stone guard construction that significantly reduces operating noise. Measured at approximately 40-50 dB during operation versus 60-70 dB for standard Badger models. For open-plan kitchens where disposal noise carries into living spaces, SoundSeal is a meaningful quality-of-life upgrade. The noise difference between Badger and Evolution series is clearly perceptible in direct comparison.
Installation: EZ Mount vs. 3-Bolt
InSinkErator uses a proprietary EZ Mount system -- a twist-lock mounting assembly that is compatible across all InSinkErator models. Upgrading from a Badger to an Evolution does not require new sink hardware -- the EZ Mount assembly is reused. Waste King and other brands use a 3-bolt mount system that is not directly compatible, requiring full hardware replacement on a switch. For existing InSinkErator households upgrading their unit: EZ Mount compatibility simplifies installation to approximately 30-45 minutes.
How We Selected These InSinkErator Models
How we picked these. We compared 5 InSinkErator disposal models across motor HP, grinding stage count, SoundSeal noise rating, mount system, grind chamber material (stainless vs. galvanized), and warranty terms (Evolution 10-year vs. Badger 1-year in-home service), cross-referencing with plumber installation reviews and homeowner reports on disposal longevity and noise over 3-10 years of use.

How We Analyze Products
We analyze Amazon review data — often thousands of reviews per product — to surface patterns that individual buyers miss. Our process aggregates star ratings, review counts, and buyer sentiment at scale, identifying which strengths and weaknesses appear consistently across the largest review samples available.
Each product earned its placement through data: total review volume, average rating, and the specific praise and complaints that repeat most often across buyers. No manufacturer paid for placement on this page. Products appear here because buyers endorsed them at scale, not because a company asked us to feature them.
We use AI to summarize review sentiment — not to fabricate opinions, but to condense what thousands of buyers actually wrote into a readable format. The pros and cons you see reflect the most common themes found in verified purchaser reviews, paraphrased for clarity. We do not claim to have accessed Reddit, YouTube, or specific publications in generating these summaries.
Prices shown reflect Amazon pricing at the time this page was last generated. Click “See Today’s Price” to get the current live price on Amazon. Read our full methodology →
