Sera Filter Wool 8.8oz

sera filter wool is designed for mechanical prefiltration, made from durable fibers that trap fine dirt particles over extended periods without clumping or breaking down. This filter wool can be cleaned and reused multiple times, making it a practical choice for all filter types.

For optimal biological filtration, we suggest pairing it with sera siporax Professional, which features a unique open-pore, three-dimensional structure for consistent pollutant removal. Before initial use, rinse sera filter media with warm water to ensure best performance.

Helpful Hint:
Using sera filter wool alongside sera phosvec･clear simplifies the removal of accumulated impurities.
