コンポストビンフィルター EcoCrock

These filters fit perfectly in my countertop bin and actually absorb smells for a good couple of weeks before needing a swap. I noticed way less fruit fly activity after I started using them, which was my main concern.

The charcoal layer in these replacement filters really does a solid job neutralizing food scraps—my bin went from musty to barely noticeable overnight. They fit snugly into the lid, so no gaps letting smells escape.

I was skeptical these would actually cut the smell from my kitchen scraps, but after a week of coffee grounds and onion peels the bin barely smells at all. Swapping the filter took about ten seconds.
