Sera – Filter Wool Filterwatte

Sera Filter Wool is designed for effective mechanical prefiltration, expertly crafted from stable fibers that trap fine dirt particles. Unlike conventional filters, our premium filter wool does not stick or collapse, ensuring longevity and consistent performance. Washable and reusable multiple times, it’s suitable for all types of filters. We recommend pairing it with Sera Siporax Professional for enhanced biological filtration, thanks to its open-pored and three-dimensional structure that promotes lasting pollutant breakdown. For optimal results, rinse the filter wool under warm water before its first use. For improved substance removal, combine with Sera.
