Eheim Classic 250 (2213) Coarse Blue Foam Filter Pad 2 Pack

Mechanical Purifying pre-filter

• Coarse material works directly where the filtration process begins.
• The water flows through and the larger dirt particles become trapped.
• Phenol-free, open-pore foam pads filters water bio-mechanically
• Layered before the biological or chemical filtration layer, it protects the filter material from coarse contamination
