The rubber splash guard inside your garbage disposal is simple, replaceable, and almost always overlooked. When it hardens or tears, you get splash-back, odors, and food that won’t feed down. Swapping it (or the whole sink flange) is a simple fix that makes an old disposal feel new.

InSinkErator Quiet Collar — Best Overall
OEM-quality guard that seals back the splash and cuts noise. It is the OEM baffle for InSinkErator’s Evolution Series. The listing states it is not for Badger models, so check which series your disposal is before you order.

Running a Badger Series disposal instead? InSinkErator makes a Baffle Upgrade Kit for its Badger disposals that swaps the fixed baffle for a removable one; InSinkErator says it keeps water and food from splashing up, muffles disposer noise and lifts out for cleaning.

OEM fit for InSinkErator Evolution Series · removable baffle
- Exact OEM fit on InSinkErator Evolution Series disposals
- Cuts both splash and grinding noise
- Pops out for cleaning
- Not for Badger Series disposals
- Replace it once the rubber stiffens
- Not a universal part
Verdict: The right baffle if you run an InSinkErator Evolution Series disposal — but not a Badger.
DGQ Removable Guard — 3-1/2 in Rubber Baffle
The listing describes a rubber splash guard that is removable for cleaning with no tools, 3-1/2 inches in outside diameter and 1-3/8 inches tall. It names no disposal brand or model, so measure your sink opening and your old guard before you order. A guard you can lift out and wash is one way to deal with a “smelly disposal.”

InSinkErator Sink Flange Kit — Best Flange Kit
If the leak is at the top of the disposal where it meets the sink, replace the mounting flange itself rather than the guard alone. The listing describes a sink flange and does not mention a baffle, so plan on the baffle as a separate part.

Quick Lock stainless steel sink mounting flange · twist-on, twist-off
- Replaces a corroded or leaking sink flange
- A genuine InSinkErator flange; the listing says the Quick Lock design is available only from InSinkErator
- Fixes the actual leak, not just the splash guard
- More of a repair than a quick accessory
- Requires dropping the disposal to install
- InSinkErator-specific fit
Verdict: Buy this when the flange itself is leaking, not just the baffle.
How to Replace a Splash Guard (Pro Tips)
Disconnect power before you start. InSinkErator says to disconnect power before installing or servicing a disposer, to turn off electrical power at the circuit breaker or fuse box before removing one, and not to put fingers or hands into a disposer. A removable baffle lifts out from the sink side. On a unit with a fixed guard, twist the disposal off its mounting ring (rotate the lower collar), pull the old guard off the top lip, and press the new one on.
InSinkErator also warns not to position your head or body under the disposer, because the unit could fall during removal or installation, and not to operate the disposer without the sink baffle in place. For a flange leak, disconnect the disposal and drain, remove the old flange, lay fresh plumber’s putty under the new flange, and re-seat the mounting hardware.
Bottom Line
Match the guard to your disposal brand for a clean seal; go with a removable guard if odor and cleaning are your main gripe.
A worn baffle is a simple part to swap. If the disposal underneath it is loud, leaking at the housing, or jams on anything softer than a lemon rind, the baffle isn’t your problem — see our disposal picks.
FAQ
Are garbage disposal splash guards universal?
No — they’re sized by brand/model (InSinkErator vs Waste King, etc.). Match yours for a proper fit.
How do I stop my disposal from smelling?
Clean or replace the splash guard (it traps food), then grind ice and citrus peels. InSinkErator says a disposer odor is usually a sign of food buildup in the grind chamber and on the baffle.
Can I replace just the splash guard?
It depends on the disposal. A removable baffle, like the Quiet Collar on an InSinkErator Evolution Series unit, lifts out from the sink side. On a unit with a fixed guard, the disposal twists off its mounting ring first. InSinkErator says to disconnect power before servicing a disposer, so do that before either job.
