Continuous or Batch Feed? The Best Garbage Disposal by Horsepower, Noise and Mount

As an Amazon Associate, we earn from qualifying purchases. This doesn’t change our recommendations or the price you pay.

The best garbage disposal for your kitchen depends on four things: how much food waste you send down the drain, how much room sits under the sink, whether you want a plug-in cord or a hardwired connection, and whether your home is on a septic tank. Horsepower gets the headlines, but feed type, grind parts, sound insulation and the mount you already have matter just as much.

We compared seven disposers from InSinkErator, Waste King, GE and Moen, from a 1/3 HP compact to a 1 HP model with all stainless steel grind components. Every pick was in stock and sold by Amazon.com when we checked. We quote motor, mount, septic and warranty claims exactly as each listing gives them, and we flag where a listing leaves a field blank or shows a number that doesn’t add up.

Below the picks you’ll find a buying guide, the safety rules that keep hands out of the grinding chamber, and what to know about leaks under the sink.

1. InSinkErator Badger 5 1/2 HP with Power Cord: Best Overall

InSinkErator’s Badger 5 is a 1/2 horsepower continuous feed disposer from the brand that says it invented the garbage disposal in 1927. This version ships with a power cord, according to the title, so it can plug into an outlet under the sink instead of being wired into a junction box.

Continuous feed means the disposer runs from a wall switch while you scrape plates and rinse, and you keep feeding scraps as it grinds. InSinkErator describes the Badger Series as “a reliable and functional choice when affordability is the prime concern,” built around its exclusive 1/2 hp Dura-Drive induction motor and long lasting galvanized steel components for a dependable grind of everyday food scraps.

Installation is one of the listing’s main selling points. InSinkErator says the compact, space-saving design fits existing InSinkErator hardware for a quick and easy install, which is useful if an older InSinkErator is already mounted under your sink. The listing doesn’t mention sound insulation, grind stages or septic use, so treat those as not stated. The warranty field reads “3-Year We Come to You In-Home Service Warranty.”

It suits most households that grind ordinary plate scrapings and peels, want a familiar brand and don’t need a quiet-running premium model. If your current disposer is an InSinkErator, the matching mount could make the swap simpler.

Why we like it

• Top-selling disposal in its category
• Cord included
• In-home service warranty field

Watch out for

The listing says nothing about sound insulation or septic systems, and the grind parts are galvanized rather than stainless steel.

2. Waste King L-111 1/3 HP Compact Disposal: Best Budget

Waste King’s L-111 is a compact 1/3 horsepower food waste disposer with a power cord already attached. Waste King pitches it as a lightweight, low profile unit that maximizes under-sink space, and the listed dimensions are 5.25 by 5.25 by 12.75 inches.

Day to day, a 1/3 HP disposer handles light jobs: plate scrapings, soft leftovers and small amounts of peel. Waste King says its 1,900 RPM, 115 volt permanent magnet motor is designed for fewer jams, and the removable splashguard can come out for cleaning, which helps when odors build up around the opening.

Installation uses Waste King’s EZ Mount, and the listing says no electrical work or expertise is needed because the cord comes pre-installed and simply plugs in. You still need a switched outlet under the sink. The listing doesn’t say what the grind components are made of, doesn’t describe the feed type and makes no sound insulation claim. Waste King backs it with a 2-year limited in-home warranty.

It suits small households, rentals, vacation homes and anyone working with a cramped sink cabinet who wants a disposer for light use at the lowest price tier on this page. Heavy cooks who grind a lot of scraps each day will want more horsepower.

Why we like it

• Lowest price tier here
• Low-profile body
• Cord comes attached

Watch out for

At 1/3 HP it is the least powerful pick, and the listing skips grind-part material and feed type.

3. GE Disposall GFC525N 1/2 HP: Best Warranty Under $100

GE’s Disposall GFC525N is a 1/2 horsepower continuous feed disposer that GE Appliances calls “The Original Since 1935.” The title names cooked meat, beans and seeds as foods it is good for grinding, and the listing recommends it for 2–4 person homes.

GE says the motor reaches over 2,600 RPM and grinds potato peels and everyday food scraps quickly. Its jam prevention technology is described as powering through the toughest foods without jamming, with “No ‘jam-buster wrench’ needed,” and an angled fin is meant to direct water forcefully so food waste drains instead of clogging.

The EZ Mount System comes with a complete easy install kit and power cord for what GE calls a simple 5-step setup that fits most kitchen setups. The blades are listed as anti-rust stainless steel that stay sharper longer. GE also claims advanced sound reduction technology for open floor plans and apartments, and calls this disposer septic safe. The warranty field reads “7-Year Replacement,” and the bullets describe a 7-year limited warranty.

It suits couples and small families, including homes on a septic system, who want a long warranty and a quieter-running claim at a mid-range price. Large families who cook from scratch every day may want a bigger motor.

Why we like it

• 7-year warranty field
• Septic safe claim
• Install kit included

Watch out for

GE recommends it for 2–4 person homes, and its sales rank trails the other picks.

4. InSinkErator Evolution 3/4 HP (EZ Connect): Best Quiet Upgrade

InSinkErator’s Evolution 3/4 HP sits in the brand’s Advanced Series. It pairs a 3/4 HP Dura-Drive induction motor with 3-Stage MultiGrind technology, which InSinkErator says is designed to prevent clogs by grinding tough food scraps the finest, and with stainless steel grind components.

Noise is the other headline. The listing describes Quiet SoundSeal technology for quieter operation than standard disposals, plus a removable Quiet Collar sink baffle at the drain opening. Day to day, that makes it a candidate for open kitchens where the sink faces the living room. It is continuous feed, so it runs from a wall switch while you feed scraps.

Installation is built around EZ Connect. The box includes an EZ Connect Hardwire Adapter, flange, gaskets, a wrench and a kitchen drain stopper, along with EZ Grip Handles, an EZ Removable Dishwasher Inlet Plug and Lift and Latch mounting. The EZ Connect Power Cord is sold separately, so plan on buying one or hardwiring it. The listing gives the size as 12.25 inches tall by 8.25 inches wide and says it is USA-assembled.

It suits households that cook from scratch, grind fibrous peels and want the quietest-sounding claims from InSinkErator on this page. The warranty field is empty, so confirm the term with the paperwork before you buy.

Why we like it

• Three grind stages
• Two separate noise features
• Stainless grind parts

Watch out for

You need a separate cord or a hardwire hookup, and the warranty field is blank.

5. Waste King L-8000 1 HP: Most Powerful

Waste King’s L-8000 is a 1 horsepower continuous feed disposer, listed in the title as the Moen L-8000 Waste King. It is wall switch activated, so it runs while you keep feeding scraps, and it comes with a pre-installed power cord for plug-in installation.

The motor is a 2,800 RPM permanent magnet design that Waste King says is sound-insulated and jams less. A 1 HP motor is aimed at large households and cooks who send a steady stream of peels, rinds and plate scrapings down the drain. Waste King describes the grind components as corrosion-resistant, all stainless steel, built for long-term reliability.

Installation uses the included EZ Mount, and the splashguard is removable for cleaning. The listing says no electrical work or expertise is needed because of the attached cord, though you still need a properly placed outlet. Waste King backs it with what the bullets call a 20-year limited in-home warranty, even though the separate warranty field is blank. The listed size is 7.5 by 7.5 by 16 inches, so measure the space under your sink and around the drain trap first.

It suits big families, frequent entertainers and anyone who has stalled a smaller unit. Smaller households can save money and cabinet space with a 1/2 HP model.

Why we like it

• 1 HP motor
• All stainless grind parts
• 20-year warranty claim

Watch out for

At 16 inches tall it needs real clearance under the sink, and the warranty term appears only in the bullets.

6. Moen Host Series GXB75C 3/4 HP Batch Feed: Best Batch Feed

Moen’s Host Series GXB75C is a 3/4 horsepower batch feed disposer with a pre-installed power cord. Batch feed works differently from a switch-operated unit: you load scraps into the chamber, then set the stopper in place to start it. Moen says the design “operates only when the stopper is engaged, helping prevent unintended use and enhancing safety.”

In daily use, that means filling the chamber, placing the stopper and letting it grind, then repeating for larger loads. There is no wall switch to flip by mistake while a hand or a dropped spoon is in the drain. Moen’s 2,700 RPM Vortex motor is described as delivering fast, efficient grinding and helping to reduce jams.

Moen lists SoundSHIELD insulation to minimize noise, and the cord comes attached so it plugs in. The mount is described as universal for quick replacement, fitting most existing 3-bolt mounting assemblies, including many competitor units, which can make swapping out an older disposer simpler. The listing doesn’t say what the grind parts are made of. The warranty field reads “8 year limited,” and the listed size is 7.5 by 7.5 by 15.63 inches.

It suits households with curious kids, renters who want a safer control method and anyone who would rather not have a wall switch near the sink. Expect a premium price for that control.

Why we like it

• Stopper-activated safety
• SoundSHIELD insulation
• 3-bolt replacement fit

Watch out for

Batch feed grinds one load at a time, and the price is the highest tier on this page.

7. Moen Prep Series GT50C 1/2 HP: Best Easy Swap

Moen’s Prep Series GT50C is a 1/2 horsepower continuous feed disposer that Moen aims at people who “slice, dice and peel as part of basic meal prep, and need a little more help with cleanup.” The title highlights Fast Track Technology and a pre-installed power cord.

Its 2,600 RPM Vortex motor is described as giving fast, powerful grinding of everyday food scraps and helping reduce jamming. As a continuous feed unit, it runs from a wall switch while you rinse and scrape. Moen describes the body as compact and lightweight for easier installation, freeing up space under the sink.

The main draw is the simple swap. Moen says it fits most existing assemblies, including other brands, so you may be able to hang it on the mounting ring that is already under your sink. The listing also says it is safe to use with properly sized septic tanks. It doesn’t state the grind-part material, any sound insulation or a warranty term, since the warranty field is blank, and its listed weight is 10.55 pounds.

It suits DIY replacements, especially when the old unit isn’t a Moen, and households doing basic meal prep on either city sewer or a properly sized septic system.

Why we like it

• Cross-brand mount fit
• Septic safe claim
• Plug-in cord

Watch out for

No warranty term or grind-part material is listed, so check the box insert.

How We Chose the Best Garbage Disposals

We compared each disposer’s Amazon listing, specs file and sales rank, and quoted only what the listings say:

• Motor: horsepower and RPM, from 1/3 HP to 1 HP.
• Feed type: continuous feed (wall switch) or batch feed (stopper activated).
• Grind parts and stages: stainless or galvanized steel, and multi-stage grinding where stated.
• Noise: named sound insulation or baffles, quoted as claims, not measured results.
• Install: pre-installed cord or hardwire, and which mount the listing says it fits.
• Warranty and availability: the warranty field, flagged when blank, and every pick in stock and sold by Amazon.com when we checked.

Garbage Disposal Buying Guide

Best In Sink Garbage Disposal: Continuous vs. Batch Feed

Most disposers are continuous feed, including five of our seven picks (the Waste King L-111 listing doesn’t state its feed type): you flip a wall switch and keep feeding scraps while it runs. Batch feed models like the Moen Host Series grind only when the stopper is in place, which Moen describes as helping prevent unintended use. Batch feed is slower for big cleanups but removes the wall switch from the equation, which many families with young children prefer.

How Much Horsepower Do You Need?

A 1/3 HP compact like the Waste King L-111 suits light use in small households. A 1/2 HP model, like the InSinkErator Badger 5, GE Disposall or Moen Prep Series, covers everyday scraps for most homes; GE recommends its 1/2 HP model for 2–4 person homes. Step up to 3/4 HP or the 1 HP Waste King L-8000 if you cook from scratch daily or have a big family.

Grind Stages and Stainless Steel Parts

The InSinkErator Evolution lists 3-Stage MultiGrind with stainless steel grind components, and the Waste King L-8000 lists all stainless steel grind components. The GE lists stainless steel blades, while the Badger 5 uses galvanized steel. Several listings don’t name the material at all, so check the manual or the brand’s spec sheet if corrosion resistance matters to you.

Best Kitchen Sink Garbage Disposal Fit: Size, Cord and Mount

Measure the height from the sink drain to the drain trap and any space taken by a water filter or hot water dispenser. Listed heights here run from 11.5 inches (Badger 5) to 16 inches (L-8000). Corded models plug into a switched outlet; the Evolution uses an EZ Connect hardwire adapter, with its cord sold separately. For mounts, the Moen Host fits most 3-bolt assemblies, the Moen Prep fits most existing assemblies including other brands, the Badger fits existing InSinkErator hardware, and the Waste King and GE models use EZ Mount systems. Our kitchen sink guide covers bowl depth and drain placement, and our kitchen faucet guide helps if you’re replacing the faucet at the same time.

Noise and Septic Claims

Quiet claims vary: the Evolution lists Quiet SoundSeal and a Quiet Collar baffle, the Moen Host lists SoundSHIELD insulation, the L-8000 says its motor is sound-insulated and the GE claims sound reduction technology. None of these listings gives a decibel figure. For septic homes, GE calls its model septic safe and Moen says the Prep Series is safe with properly sized tanks. The EPA’s septic care guide still advises that if you have a garbage disposal you limit its use, and notes your tank may need pumping more often if you use one.

Best Sink Strainer for Garbage Disposal Use

A drain stopper or strainer keeps silverware and bottle caps out of the grinding chamber when the disposer is off. The Evolution ships with a kitchen drain stopper, and the Moen Host needs its stopper to run at all. Whatever you choose, it must fit your disposer’s flange, so check the brand before buying a replacement.

Garbage Disposal Safety and Water Damage

A disposer combines a motor, electricity and water in a closed cabinet, so a few rules matter:

• Never put your hand in the chamber. Use tongs to pull out a dropped utensil, and only after the power is off.
• Cut the power before servicing. Unplug a corded unit or switch off the breaker for a hardwired one before you clear a jam or look inside.
• Use the reset button and hex wrench. Most disposers have an overload reset button on the bottom, and many accept a hex wrench in the base to free a stuck grinder by hand; your manual shows where.
• Know what not to grind. Grease, fats and oils clog pipes, and the EPA lists coffee grounds and fats among things to keep out of the drain for septic homes.
• Check for leaks. Look under the sink for drips at the sink flange, the dishwasher connection and the drain outlet. The EPA WaterSense program says household leaks can waste nearly 1 trillion gallons of water annually nationwide.
• Hire a pro for wiring. Hardwiring and adding an outlet are jobs for a licensed electrician, and a licensed plumber can handle drain and dishwasher connections.
• Review your coverage. Sudden water damage from a burst line is treated differently from slow leaks in many policies. Our Ohio homeowners insurance guide and Ohio renters insurance cost guide explain what to ask your agent.

Frequently Asked Questions

What is the best garbage disposal for most homes?

The InSinkErator Badger 5 with Power Cord is our overall pick. It ranks #1 in Garbage Disposals, uses a 1/2 HP Dura-Drive induction motor, comes with a cord and lists a 3-year in-home service warranty.

What is the best in sink garbage disposal for a family with kids?

A batch feed model like the Moen Host Series GXB75C runs only when the stopper is engaged, so there is no wall switch to flip by accident. Moen says this helps prevent unintended use.

Is 1/2 HP enough for a garbage disposal?

For most households, yes. GE recommends its 1/2 HP Disposall for 2–4 person homes. Larger families or heavy cooks may prefer 3/4 HP or the 1 HP Waste King L-8000.

Can I use a garbage disposal with a septic tank?

Some listings say so: GE calls its GFC525N septic safe, and Moen says the Prep Series is safe with properly sized tanks. The EPA advises limiting disposal use on septic and says tanks may need pumping more often.

Do I need an electrician to install a garbage disposal?

Corded models like the Waste King, GE and Moen picks plug into an outlet under the sink. If you need a new outlet or are hardwiring a unit like the InSinkErator Evolution, hire a licensed electrician.

The Bottom Line

The InSinkErator Badger 5 with Power Cord is the best garbage disposal for most kitchens: the top seller in its category, with a 1/2 HP motor and an in-home service warranty field. The Waste King L-111 is the budget compact, the GE Disposall pairs a septic safe claim with a 7-year warranty field, and the Moen Prep Series makes cross-brand swaps easier. For more power or less noise, look at the InSinkErator Evolution and the 1 HP Waste King L-8000, and choose the Moen Host Series if you want batch feed control.
