Review on 🔍 Aqueon (2 Pack) Minibow Replacement Filter Cartridge Size Small - 6 Cartridges Per Pack / 12 Total by Donna Taflinger

These filters fit well and aren't entirely useless, but they've definitely come up short over the past few years. Previously, these filters were filled with activated carbon; now they are not even half full. See photo. Even shaking the filter to distribute the activated charcoal more evenly does not provide full coverage. I would buy another brand if I could find one that would fit my tank.
