Sera FilterWool[Weight - 250g]

Sera filter wool for mechanical prefiltration is crafted from durable fibers that effectively capture smaller dirt particles for an extended period without clumping or collapsing. This filter wool is washable and can be reused multiple times. It is compatible with all types of filters.

For optimal biological filtration, we recommend using sera siporax Professional. This product features an open-pored, three-dimensional structure that ensures efficient breakdown of pollutants.

Before first use, it is essential to rinse sera filter media under warm water.

When paired with sera phosvec･clear, sera filter wool facilitates the removal of bound substances more effectively.
