4 manufacturers, 33 filter models with documented replacements.
- Aqua-Tech4 modelsAqua-Tech is a small line of hang-on-back power filters. Each filter size takes a numbered EZ-Change cartridge, and the same cartridge number is listed for more than one filter size.
- Aqueon17 modelsAqueon makes hang-on-back, internal and canister aquarium filters. Its replacement cartridges come in four sizes — Extra Small, Small, Medium and Large — and each size has a manufacturer-published list of the filter models it fits.
- Fluval8 modelsFluval's canister filters use a family of replacement media rather than a single sealed cartridge. Because the 06 and 07 Series share much of that media, one product is often listed for several filter sizes.
- Marineland4 modelsMarineland's Penguin BIO-Wheel power filters use branded Rite-Size replacement cartridges. The owner's manual documents which Rite-Size cartridge belongs to each Penguin model.
