Sera Filter Wool
For mechanical prefiltration of fine dirt particles
Sera filter wool for mechanical prefiltration consists of stable fibers that retain finer dirt particles for a longer time without sticking or collapsing. Sera filter wool can be washed out several times. Suitable for all filters.
We recommend sera siporax Professional for biological filtration. Sera siporax Professional is open pored and three dimensional — for lasting pollutant breakdown.
Filter media must be rinsed under warm water before first use.
Tip
When used in combination with sera phosvec・clear, sera filter wool makes it easier to remove bound substances.

The filter wool works well as a prefilter. It holds fine particles without clogging and stays effective after multiple washes. Combined with phosvec・clear, cleaning becomes much easier.

Good for initial filtration. The fibers don’t collapse and retain dirt efficiently. I rinsed it before first use as recommended and it performed smoothly.

Stable and long-lasting. I’ve used it in my aquarium setup for several months and it still functions well. No sticking or breakdown observed.
