【Aquarium Carbon Filter Compatibility】
The Aquarium Carbon Filter is compatible with Tetra Whisper EX series powered filters, including the Whisper EX30, EX45, and EX70 models.

【Whisper Fish Tank Filter Size】
The replacement tetra aquarium filter measures 6.7 inches x 5.1 inches, making it a large size.

【High-Efficiency Filtration】
The tetra carbon fish tank filter uses a dual-layer composite structure of high-density polyester fiber and enhanced high-quality activated carbon. It mechanically filters out food residue and other impurities, removes odors, and one cartridge can handle all filtration needs, leaving water clear and transparent.

【10-Pack Value Set】
Each box contains 10 aquarium carbon filters, sufficient for long-term use. It is recommended to replace them every 2-4 weeks to maintain optimal filtration performance.
