Filter cartridges for mechanical and biological filtration

Dirt particles become trapped in the porous foam material. At the same time, the material offers a large colonisation surface area for the purification bacteria. Even after a short maturation period the foam cartridges perform not only mechanical water purification, but also biological decomposition of harmful substances.

Product Features:

• Foam traps dirt particles mechanically
• Bacteria cultures colonise in the pores
• Reusable several times over
• To clean just rinse and squeeze out
