Eheim Classic 2217/600 White Wool Filter Pads

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.
