I replaced the old sponge in my Bio Sponge Air Driven Filter and it fits perfectly. The material is dense and holds water well, which helps maintain good filtration. It’s easy to clean and has not lost its shape after several weeks of use.

Fits the Aquatop CAF 180 filter exactly. The sponge is sturdy and maintains its structure even after regular cleaning. I noticed better water flow after installing it.

Great replacement for my XY-2837 filter. It matches the original size and provides consistent filtration. No issues with shedding or breaking after a month of use.
