Sera Filter Wool 3.5oz

Sera Filter Wool, weighing 3.5oz, is designed for mechanical prefiltration, utilizing durable fibers to trap small dirt particles over extended periods without clumping or breaking down. This filter wool can be cleaned and reused multiple times, making it a cost-effective choice. It is compatible with all types of filtration systems.

For optimal biological filtration, we suggest pairing it with Sera Siporax Professional, which features a unique open-pored, three-dimensional structure for consistent pollutant removal. Before initial use, rinse Sera filter media under warm water to prepare it for your system.

Pro Tip:
Combine Sera Filter Wool with Sera Phosvec･Clear to simplify the removal of accumulated substances from your filter setup.
