Quietest Garbage Disposals — 2026 Buying Guide
Open-plan kitchens and thin apartment walls make a loud garbage disposal impossible to ignore. The quietest quiet garbage disposal on the market today, the InSinkErator Evolution Quiet Collar, runs at 60-65 dB, quieter than a normal conversation. A standard InSinkErator Badger 5 runs 75-80 dB, about the volume of a vacuum cleaner running three feet away. That 15-20 dB gap is the difference between a kitchen tool you forget about and one that stops conversations.
This guide ranks the top five quiet disposal models by measured dB, explains what noise-reduction technology actually does mechanically, and gives budget buyers four ways to quiet an existing unit without replacing it. We recommend bookmarking the dB comparison table: it is the only cross-brand noise reference of its kind available outside a paywall. Jump to our quiet model picks or compare dB ratings directly.

The Badger 5 is the reference point here, roughly vacuum-cleaner loud. Every model above it represents real, measurable noise reduction.
Is this guide for you?
This guide is for you if:
- You are shopping for a new disposal and noise is a priority
- You live in an apartment, condo, or open-plan kitchen
- You want specific dB data to compare models before you buy
- Your existing disposal is just loud by design, not broken
This guide is NOT for you if:
- Your disposal suddenly got louder, that points to a mechanical problem, not a quiet-model gap. Read our types of garbage disposal noise guide first.
- Your disposal makes a sudden grinding noise, that is a jam or wear issue, not a noise spec issue.
- You want the best garbage disposal overall regardless of noise, different set of tradeoffs.
How quiet is “quiet”? (dB comparison table)
What makes a garbage disposal quiet? SoundSeal foam insulation absorbs motor noise at the source, permanent magnet motors produce less vibration than induction motors, and vibration isolation mounts prevent that vibration from radiating into the sink bowl and cabinet walls. The quietest models combine all three, according to EPA noise pollution guidelines{:target=“_blank”} and the product specs below.
For context: a whisper registers around 30 dB, a normal conversation at 60 dB, a vacuum cleaner at 70-75 dB. Standard disposals run at 75-82 dB. OSHA noise exposure limits{:target=“_blank”} set the occupational hazard threshold at 85 dB for 8-hour exposure, disposals run for 30-90 seconds at a time, well below that level even at peak noise.
One thing that often surprises homeowners: cabinet resonance amplifies disposal noise 5-10 dB above the motor’s actual output. A 70 dB motor in an empty under-sink cabinet with loose mounting can register as 78-80 dB in the kitchen. That matters when comparing specs.
| Model | HP | dB Range | Technology | MSRP |
|---|---|---|---|---|
| InSinkErator Evolution Quiet Collar | 1 HP | 60-65 dB | SoundSeal + permanent magnet | $349-$399 |
| KitchenAid KKDS100S | 1 HP | 65-70 dB | Vibration isolation mount | $300-$350 |
| InSinkErator Evolution 3/4 HP | 3/4 HP | 70-75 dB | Partial SoundSeal | $249-$299 |
| Moen Host GXS75C | 3/4 HP | 72-76 dB | Permanent magnet | $179-$199 |
| Waste King L-8000 | 3/4 HP | 74-79 dB | Permanent magnet | $90-$120 |
| InSinkErator Badger 5 (baseline) | 3/4 HP | 75-80 dB | None | $149-$199 |
SoundSeal reduces noise 10-15 dB versus an uninsulated equivalent. Permanent magnet motors deliver 5-8 dB less noise than induction motors running the same load. We used these figures as the primary ranking criteria for the picks below.
Top 5 quietest garbage disposals
1. InSinkErator evolution quiet collar, quietest overall (60-65 dB)
Specs: 1 HP, 60-65 dB, 4-stage MultiGrind, 10-year warranty, $349-$399
The Evolution Quiet Collar is the quietest garbage disposal available at retail in 2026. SoundSeal insulation wraps the entire motor housing in multiple foam layers, absorbing both airborne sound and structure-borne vibration before either reaches the sink. The 1 HP permanent magnet motor runs quieter than InSinkErator’s own induction-motor Badger line, and the 4-stage MultiGrind system pulverizes food waste finely enough to reduce the total run time per cycle.
For a deeper look at the full Evolution line, see our full InSinkErator Evolution review.
Pros:
- Quietest in class at 60-65 dB
- Best warranty in the comparison at 10 years
- 4-stage grinding handles tough food waste, reduces overall run time
Cons:
- Premium price ($349-$399), roughly $200 more than the Moen option
- 1 HP may require a 20-amp circuit in some older installs
- Heavier unit; installation takes slightly longer
Best for: Open-plan kitchens, households that run the disposal multiple times daily, anyone who wants to set it and forget it.
See the InSinkErator Quiet Series product page{:target=“_blank”} for current specs.
2. KitchenAid KKDS100S, premium alternative (65-70 dB)
Specs: 1 HP, 65-70 dB, vibration isolation mount, 3-year warranty, $300-$350
The KKDS100S lands 5 dB above the Quiet Collar with a different approach: instead of foam insulation, it uses a vibration isolation mount to decouple the motor from the sink bowl. At 65-70 dB it is still well below vacuum-cleaner territory, and the stainless steel exterior makes it a better fit for high-end kitchens where aesthetics matter alongside quiet operation.
Pros:
- Near-Quiet-Collar noise level at a slightly lower price point
- Premium stainless exterior suits visible or semi-visible under-sink setups
- Compact design fits most standard cabinets
Cons:
- 3-year warranty versus the 10-year Evolution, a real gap for a $300+ unit
- Fewer repair resources available compared to InSinkErator’s dominant market share (approximately 70% of US residential installs)
Best for: High-end kitchens where visual finish matters and quiet operation is the secondary priority.
3. InSinkErator evolution 3/4 HP, mid-range sweet spot (70-75 dB)
Specs: 3/4 HP, 70-75 dB, partial SoundSeal, 4-stage MultiGrind, 10-year warranty, $249-$299
This is the right pick for buyers who want Evolution-level warranty coverage without paying for the Quiet Collar premium. The partial SoundSeal package brings noise down to 70-75 dB, meaningfully quieter than the Badger 5 at 75-80 dB, and the 4-stage grinding is identical to the premium 1 HP unit.
Pros:
- Same 10-year warranty as the Quiet Collar
- 4-stage MultiGrind handles harder food scraps
- Real noise reduction versus uninsulated models
Cons:
- Partial SoundSeal means 10 dB louder than the Quiet Collar at peak
- Costs $100 more than the Moen GXS75C for a smaller noise gap between them
Best for: Homeowners who want Evolution reliability and warranty without full premium pricing.
4. moen host GXS75C, best budget quiet disposal (72-76 dB)
Specs: 3/4 HP, 72-76 dB, permanent magnet motor (4,956 RPM under load), 7.3” width, 3-year warranty, $179-$199
We found the Moen GXS75C to be the most practical option for noise-conscious buyers on a budget. At 74 dB average in testing (72-76 dB peak), it sits between the mid-range Evolution and the Badger 5 baseline, quieter than most of what is installed in US kitchens right now. Its permanent magnet motor runs at 4,956 RPM under actual load, producing a lighter, higher-frequency grinding sound that most people perceive as less intrusive than the low-frequency hum of an induction motor.
The 7.3” width is the narrowest in its class; standard full-width units run 10-11 inches. That matters for tight under-sink cabinets in apartments or older homes. Adding $15-$30 rubber isolation pads at install time drops perceived noise another 5-8 dB, bringing the total system cost to roughly $195-$225 for noise performance approaching the Evolution 3/4 HP at $249-$299.
Note: some apartment leases require landlord approval for appliance replacement. That’s not unique to the Moen, confirm with your landlord before any disposal swap.
Pros:
- $100-$200 cheaper than comparable Evolution models
- Narrowest profile in class (7.3”) for tight cabinet installs
- Permanent magnet motor reduces vibration versus induction
Cons:
- 3-year warranty (versus 10-year on Evolution models)
- Single-stage grinding produces slightly coarser output
- Expected lifespan 5-7 years versus 10-12 years for premium units
Best for: Apartments, small kitchens, budget buyers. Add isolation pads on install for best noise results.
5. waste king L-8000, budget permanent magnet option (74-79 dB)
Specs: 3/4 HP, 74-79 dB, permanent magnet motor (2,600-2,800 RPM), 5-year warranty, $90-$120
The L-8000 uses the same permanent magnet motor technology as the Moen. 5-8 dB quieter than an equivalent induction unit, but without any additional noise insulation. At 74-79 dB it is approaching Badger 5 territory, so calling it “quiet” requires some qualification. The main advantage over the Badger 5 is motor character: the higher-RPM permanent magnet produces a lighter, less intrusive sound even at similar dB levels.
Pros:
- Lowest price in this comparison at $90-$120
- Permanent magnet motor is lighter-sounding than induction at the same dB
- 5-year warranty is decent for the price
Cons:
- No noise insulation; real-world noise approaches the Badger 5 baseline
- 5-year warranty is shorter than both Evolution (10-year) and Waste King’s own premium L-8000 (20-year on some configurations)
Best for: Renters or buyers who want slightly quieter than baseline without paying for insulation technology.
The noise tech behind quiet disposals
SoundSeal insulation (InSinkErator proprietary)
SoundSeal is multiple layers of noise-absorbing foam wrapped around the motor housing, exclusive to the InSinkErator Evolution series. The foam dampens both airborne sound radiating from the motor casing and structure-borne vibration that would otherwise travel through the mounting hardware into the sink. The result is 10-15 dB noise reduction versus an uninsulated motor of the same HP rating, the biggest single noise-reduction mechanism available in consumer disposals.
The technology is proprietary to InSinkErator and cannot be added to a third-party disposal after purchase. The premium over an uninsulated model runs approximately $100-$200 depending on which Evolution model you compare to the Badger equivalent.
Permanent magnet motors (moen, waste king)
Standard InSinkErator Badger disposals use induction motors running at around 1,725 RPM. Permanent magnet motors, used by both Moen and Waste King, run at 2,600-2,800 RPM nominal (the Moen GXS75C measures 4,956 RPM under actual load). The higher speed produces a lighter, higher-frequency sound that people perceive as less intrusive than the low bass hum of an induction motor. The practical noise advantage is 5-8 dB versus an equivalent induction motor under the same load.
To understand what the motor is doing during motor humming during normal operation, and when humming indicates a problem, see our motor diagnosis guide.
Vibration isolation mounts
The rubber gasket between the disposal body and the sink flange prevents motor vibration from transmitting into the sink bowl and cabinet walls. Without this mount, cabinet resonance amplifies disposal noise 5-10 dB above the motor’s actual output, turning a 70 dB motor into an 80 dB kitchen experience. Premium models include isolation mounts from the factory. For existing installs, a rubber isolation pad kit costs $15-$30 and can be added in about 30 minutes without special tools.
4 ways to quiet your existing disposal (no replacement needed)
These methods address vibration transmission and cabinet resonance, the gap between motor noise and what you actually hear in the kitchen. We tested all four on standard residential installs and found tightening mounting bolts first delivers the best return: it costs nothing and cuts vibration 30-40% on its own.
-
Tighten the mounting bolts (free, 15 minutes). Loose mounting bolts are the most common source of excess vibration. Three bolts connect the disposal to the sink flange; tighten each a quarter-turn clockwise with an adjustable wrench. Do not overtighten, one firm snug turn is enough. Result: 30-40% vibration reduction at zero cost.
-
Install rubber isolation pads ($15-$30, 30 minutes). Isolation pads sit between the mounting ring and the sink flange, preventing direct metal-to-metal vibration transmission. A pad kit costs $15-$30 and reduces perceived noise 5-8 dB, the same improvement as upgrading from a Badger 5 to a Waste King L-8000.
-
Add mass loaded vinyl to the cabinet interior ($30-$60, 1 hour). Acoustic foam or mass loaded vinyl adhered to the cabinet walls below the sink absorbs the resonance frequencies that make disposals sound louder than they are. Result: 2-5 dB reduction in overall kitchen noise perception.
-
Run cold water before and during operation. Cold water keeps food particles firm and reduces the grinding load per cycle. Smoother particle flow means less vibration per second of run time. It takes nothing extra beyond the habit.
These reduce combined noise 5-15 dB with $0-$60 in materials. A premium quiet model reduces 10-20 dB from the baseline. If noise is a serious priority, replacement is the more reliable fix, but these tips are worth exhausting first.
Which quiet disposal is right for you?
Budget under $200: We recommend the Moen Host GXS75C at $179-$199. Add $15-$30 rubber isolation pads at install and total system cost stays under $225 while noise performance lands around 67-70 dB perceived, close to the Evolution 3/4 HP range without the warranty premium.
Budget $250-$300: The InSinkErator Evolution 3/4 HP at $249-$299 makes the most sense. The 10-year warranty, 4-stage grinding, and partial SoundSeal add up to a long-term buy that the Moen cannot match on durability.
Best quiet regardless of cost: InSinkErator Evolution Quiet Collar at $349-$399. At 60-65 dB with a 10-year warranty, it is the definitive answer for open-plan kitchens and households that run the disposal multiple times daily. The roughly $200 premium over the Badger 5 works out to about $10-$13 per dB of noise reduction, reasonable if noise is the primary concern.
Small kitchen or apartment: The Moen GXS75C’s 7.3” width (versus 10-11” for most standard units) makes it the only clear choice when under-sink space is tight.
Open-plan kitchen, used daily: InSinkErator Evolution Quiet Collar. The 4-stage grind means shorter cycles; the SoundSeal means you can use it while people are eating nearby.

FAQ
What makes a garbage disposal quiet?
Three technologies reduce garbage disposal noise: SoundSeal foam insulation reduces noise 10-15 dB by wrapping the motor housing (InSinkErator proprietary), permanent magnet motors run 5-8 dB quieter than equivalent induction motors by producing lighter-sounding higher-frequency vibration (used by Moen and Waste King), and vibration isolation mounts prevent cabinet resonance that otherwise amplifies motor noise 5-10 dB. The quietest models combine all three.
Which garbage disposal is the quietest?
The InSinkErator Evolution Quiet Collar is the quietest garbage disposal available at retail in 2026, running at 60-65 dB, quieter than a normal conversation at around 60 dB, compared to the standard InSinkErator Badger 5 baseline of 75-80 dB, which is roughly equivalent to a vacuum cleaner. The KitchenAid KKDS100S is the closest competitor at 65-70 dB.
How many decibels is a quiet garbage disposal?
Under 70 dB is the threshold for quiet garbage disposals. Under 65 dB is very quiet. Standard models run 75-82 dB. For context: a normal conversation is around 60 dB, a vacuum cleaner runs 70-75 dB, and OSHA’s occupational noise threshold is 85 dB for sustained 8-hour exposure.
How do I make my garbage disposal quieter without replacing it?
Tighten the three mounting bolts under the sink (free, 30-40% vibration reduction), install rubber isolation pads between the mounting ring and sink flange ($15-$30, 5-8 dB reduction), and add mass loaded vinyl to the cabinet interior walls ($30-$60, 2-5 dB reduction). Running cold water before and during operation reduces grinding load and vibration per cycle at no cost.
Is InSinkErator Evolution worth the price for noise reduction?
Yes, if noise is the primary concern. The Evolution Quiet Collar at $349-$399 is 15-20 dB quieter than the Badger 5 at $149-$199. At a $150-$200 price premium, that works out to roughly $10-$13 per dB of noise reduction, plus the 10-year warranty versus the Badger 5’s shorter coverage. If budget matters, the Evolution 3/4 HP at $249-$299 delivers meaningful SoundSeal insulation with the same 10-year warranty.
Are permanent magnet disposals quieter than induction?
Yes, 5-8 dB quieter under equivalent loads. Waste King and Moen use permanent magnet motors running at 2,600-2,800 RPM nominal; InSinkErator’s Badger series uses induction motors at around 1,725 RPM. The higher-speed permanent magnet motors produce a lighter, higher-frequency sound that most users perceive as less intrusive than the deeper hum of an induction motor, even when measured dB levels are similar.
