About This

• You are buying a pack of 4 compatible filter foam pads to fit the Fluval 404/405/406 range of external filters
• These pads are made from exactly the same material as the Fluval originals, just offering a massive saving.
• The pads measure 280mm X 72mm X 20mm.
• The sponges contain the biological cultures, for purifying your water, whilst also mechanically filtering the water by removing particulate waste.
• Please Note: This is NOT a genuine Fluval original filter, it is a Finest-Filters alternative which performs the same job.
