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.

The filters work great! And I can’t beat the price
Better than expected
These filters looked different than the standard ones I buy , but worked perfectly
I received the wrong filters from what I had ordered, but the correct filters were promptly shipped along with a return envelope to send the other filters back. Excellent service.
Great replacement filters
This works really good and great price
YFS Brand size E filter cartridges
I use these in my Discus Aquarium, they keep the water very clear. I have 2 Emperor 280's and 1 Emperor 400 in the tank. The filters are filled with a superior quality charcoal that does not require a lot of rinsing like the manufacturer's cartridges. Polyester on both sides instead of louvers that let bits of charcoal escape into the filter body. American Made too. Excellent Product
