Quiet Operation, Fully Submersible Design (<35dB): Built with a low-noise motor and anti-vibration suction cups, this sponge filter delivers quiet performance — ideal for bedrooms, offices, or other peaceful environments. Fully submersible and designed for flexibility, it also supports lower water levels for creative tank setups.

Cost-Effective & Reusable Filtration: Includes 2 additional sponge layers and a built-in waste container to capture debris, algae, and odors. The washable sponges are reusable, and the filter media can be easily swapped to match your setup — reducing the need to replace the entire filter unit frequently.

Tool-Free Cleaning & Maintenance: The transparent, 3-stage housing makes it easy to inspect and clean. Just twist off the top cap, remove the sponge, rinse, and reassemble — all without tools.

Dual-Layer Safety Design for All Tank Layouts: Fine mesh intake prevents small fish and shrimp from being sucked in, ensuring safe operation. The double-layer filter system allows you to mix and match filter media for better performance. Energy-efficient and low-noise, it provides crystal-clear water with minimal maintenance effort.
