Product review
Measure the lid opening before ordering: each round filter is 3.75 inches in diameter and intended for most small, round countertop compost buckets.
These discs are made with activated charcoal to capture and neutralize odors at the source rather than just masking them, helping keep the area around your kitchen bin more pleasant between emptyings.
A single purchase includes four replacement filters. Used on a regular schedule — roughly every two to four months depending on use — the set provides continuous odor management through seasonal changes.
Installation is simple: lift out the spent disc and drop in a fresh one. The filters are designed to be a no-tools replacement, yet they can also be trimmed to fit nonstandard openings when needed.
Manufactured for daily home composting, these charcoal filters are compatible with a wide range of countertop setups, including 1.3-gallon recycling/composter models. The maker offers a 45-day satisfaction guarantee so you can try them risk-free.
Pros
- Absorbs odors rather than masking them
- Easy drop-in replacement, can be trimmed if needed
- Four discs provide several months of coverage
Cons
- May require trimming for some lids
- Can shed charcoal particles if handled roughly
- Requires regular replacement for peak performance
VerdictThese 3.75-inch activated carbon discs offer straightforward odor control for small countertop composters. They work by absorbing unwanted smells, install as simple drop-in replacements, and can be trimmed if your lid requires a tighter fit. One pack contains four filters — enough to rotate fresh discs every two to four months — and they’re compatible with many brands and 1.3-gallon recycling unit

Does the job
Slotted into my small cupboard bin and helped control odors while still allowing some airflow.

Tour Guide 5/5
Slightly big but easy to tailor
They arrived a touch too large for my lid, but a quick trim solved it. Stops compost smells from escaping and works as intended.

Diane Jones 5/5
Keeps bucket fresh
My compost pail stays odor-free and the filters last quite a while. I’d purchase them again.

Used in a printer exhaust mod
I adapted one to my 3D printer’s exhaust in a small apartment and it helped reduce odors and fumes while printing ABS and polycarbonate.

Andrew Wallace 5/5
Exactly the right fit
Perfect for my counter-top composter and effective at keeping odors down.

Chance 1/5
Awkward sizing for many uses
Too oddly sized to be useful in a lot of situations. Cutting them down is not pleasant; only buy if sure of the fit.

Deb 5/5
Impressed by performance
Came with my countertop bin and worked surprisingly well. I bought a spare pack since they seem to last a long time.

Hard-to-find size, works well
These fit my countertop composter and stay in place. No mess of charcoal bits when bumped and they do what they should.

Good for my Cooler bin
They fit my Cooler compost bin perfectly. You can refresh them, but replacing regularly keeps fruit fly smells away; no odor unless I lift the lid.
