EHEIM Filter Cartridges for Eheim 2003 (Aquaboss)

The filter set, specially adapted to the 2003 filter, consists of two filter cartridges for mechanical and biological filtration, which allow fine particles to be retained in the porous foam material.
At the same time, the material provides a large colonization surface for purification bacteria. Even after a short maturation period, the foam cartridges fulfill not only mechanical water purification, but also biological decomposition of harmful substances.

The cartridges can be reused several times.
To clean them, simply rinse and squeeze them, so that the bacteria cultures are not completely destroyed.
