It's the same. Just cotton like fluff made from very fine polyester fibers. It's cheap and mechanically polishes water at least as well as anything else you can buy. I still like to use a coarse filter sponge as my first canister stage.
You can alternately use the blue bonded filter pads. It comes in a pack and can be cut to fit any filter. I use whichever one I have or the store has on hand. They both serve the same purpose. Again, their isn't anything wrong with using whatever filter media that the manufacture recommends. It just costs more and anything that cost more to buy often gets replaced less often. At least it does on my budget! lol
