The Tetra Whisper 40i Internal Filter, designed for aquariums, offers a quiet and convenient 3-stage filtration system. This submersible filter mounts on the inside of the aquarium, allowing the tank to be placed flush against a wall and easily concealed with decor. The included air pump provides bubbles that move water through the filter, efficiently filtering and oxygenating the aquarium.

The water flows through Ultra-Activated carbon, which absorbs odors and discoloration, as well as through the dual-sided mesh of the Bio-Bag Filter, trapping debris and fish waste. This filter can handle up to 170 GPH while oxygenating the water. The Tetra Whisper 40i Internal Filter can be easily adjusted to accommodate high or low water levels with the included mounting clip.

Each unit comes with the filter, air pump, 2 feet of airline tubing, and one large Tetra Whisper Bio-Bag Filter cartridge, which needs to be replaced monthly. The replacement small filter cartridges are also available. This filter is suitable for 20-40 gallon tanks.

Since 1951, Tetra has been a leading authority in the world of fish food knowledge, and fishkeeping enthusiasts have relied on the brand for products and solutions that add convenience and beauty to their home aquariums. Whether you're an experienced hobbyist or just starting out, Tetra offers a comprehensive range of high-quality fish food, innovative equipment, test kits, and decorative elements to cater to all your fishkeeping needs.

The Tetra Whisper 40i Internal Filter is a versatile and efficient all-in-one air pump and water filter system. Its internal design allows for the tank to be placed flush against a wall, making it a space-saving and visually appealing option. The dense, dual-sided mesh effectively traps debris and fish waste, while the air-driven design filters up to 170 GPH while oxygenating the water. The convenient design features large, easy-to-change Bio-Bag cartridges, ensuring hassle-free maintenance for aquarium enthusiasts.
