The EHEIM coarse filters are used for the mechanical and biological purification of aquarium water. The porous foam material of the filter cartridges removes dirt particles mechanically from the water. After a short running-in phase beneficial cleaning bacteria start to colonize the lage surface area of the foam cartridges. These bacteria support biological water purification by breaking down harmful substances in the water, efficiently.


  • The coarse filter made of phenol-free foam is easy to replace
  • Efficient biological and mechanical cleaning of aquarium water
  • Suitable for the clarification of fresh and sea water
  • Optimal colonization conditions for cleaning bacteria
  • The filer cartridges are reusable


The coarse filter cartridge is designed for a longer service life and should only be rinsed out and briefly squeezed out during regular cleaning invervals of the internal filter. In this way, the bacterial cultures colonizing the cartridge remain intact and continue to support biological water purification.



2 coarse filters are included in each package.



Eheim stands for very good aquarium filters made in Germany. External and internal filters as well as filter pumps are only a few of the products manufactured by Eheim that are also suitable for planted tanks or aquascapes. The highest quality standards and innovative products will always be connected with the name Eheim for many aquarium enthusiasts.
