Our aquarium filter replacement cartridges come pre-assembled, filled, ready to be used and will out perform the OEM cartridges provided with the filters!
Support American made products. All materials sourced and manufactured right here in the USA.
These replacement cartridges are constructed with polyester on both sides and contain extra amounts of professional grade carbon. Our carbon has been air-vacuumed, which results in a lighter more absorbent filter cartridge.
