• Foam filter pad

    EHEIM filter pads are made of specially structured materials and meet the requirements for layer structure in EHEIM external filters with different functions. Depending on the type, they combine mechanical, biological and adsorptive filtration.

    Foam filter pads

    Specially structured materials provide outstanding purification. Water permeates them evenly, and coarse particle residues as well as even the finest particle residues are trapped mechanically. After a short run-in period purification bacteria lodge in the special foam material and ensure the intensive, biological decomposition of toxins.In addition, carbon pads has an adsorptive effect: dissolved pollutants are trapped on their surface and thereby removed from the water cycle.
