Filter Cotton No.01 Quality is a high-performance ecological ultrafiltration cotton designed to provide efficient mechanical filtration for aquariums and ponds. With its ultra-thin yet dense structure, this filter cotton effectively intercepts fine particles, debris, and waste, helping maintain crystal-clear water and a healthy aquatic environment. Made from non-toxic and odorless materials, this filtration cotton is completely safe for use in freshwater and saltwater aquariums. Its advanced fiber structure allows excellent water flow while trapping suspended impurities, preventing them from spreading throughout the tank. This makes it ideal for use as a pre-filter or polishing filter layer in canister filters, top filters, sump systems, and pond filters. The C-2 ecological ultrafiltration cotton is designed for durability and long-term use. It offers strong scrub resistance and tensile strength, ensuring it does not tear or deform easily during cleaning. Even when fully soaked in water, the cotton does not fall apart, maintaining its structure and filtration efficiency over time. With its high-efficiency interception capability, this filter cotton reduces the load on biological media by capturing fine waste early in the filtration process. This helps extend the life of your biological filter media and improves overall filtration performance. The 60 × 40 cm size allows flexible use and can be easily cut to fit different filter compartments and filtration systems. Whether you are setting up a new aquarium or upgrading your existing filter, Filter Cotton No.01 Quality provides reliable and consistent mechanical filtration.
