Fluval U Series Foam Pads are genuine replacement mechanical filter media designed specifically for Fluval U1, U2, U3 and U4 Underwater Filters. Each foam pad is shaped to fit securely inside the correct filter chamber, helping capture larger particles, fish waste and suspended debris before they move further through the filtration system.
The foam structure is designed to provide efficient water flow while reducing premature clogging, making these pads an important part of regular Fluval U Series filter maintenance. Each size is supplied as a 2 pack and should be selected to match your specific U Series filter model.
