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.
