Specially structured materials that provide outstanding water purification for Classic 250 (2213).

• Water permeates the pads 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.

EHEIM pads are specifically designed to work with EHEIM canister filters for optimum performance.
