What a Wonderful World

The Whisper EX Series Filtration Systems take the ease of maintaining an aquarium to a whole new level for beginners to hobbyists alike. Every new feature in this system had been designed with simplicity and convenience in mind. This is truly the intuitive filtration system that keeps your water clean and your fish and plants healthy. With four models available, you will be sure to find one that accommodates your aquarium size.

These are the 4 WhisperEX Filter models available to you that come mostly pre-assembled.

The WhisperEX Filter easily hangs on the back of your tank.

The Bio-Scrubber helps ensure crystal clear water.

The Essence of Ease

It is ready to go right out of the box, you only have to adjust the intake tube to the proper depth and plug it in. No priming of the filter is necessary.

There is an easy access door located on top of the filter that stays in place while changing out the filter cartridges and the Filter Cartridge Carrier helps keep your hands away from used cartridges, helping eliminate any unwanted drips. The Whisper EX Filters also have a submerged motor requiring less maintenance than other external models while creating one of the most silent filters on the market.

The Contour of Clean

Whisper EX Filtration Systems have scientifically engineered water flow. The rounded shape creates a circular water flow that prevents sediment from forming in the bottom of the system chamber. Water is forced through multi-density carbon filters that suspend the carbon for greater contact and improved filtration. The filters are designed with a multi-density floss structure that captures a range of unwanted particles. The Activated Carbon in the Filter Cartridges allow for the elimination of odors, water discolorations, and detrimental toxins. Whisper EX models also have Tetra's patented Bio-Scrubber technology. The bristles of the Bio- Scrubber provide more surface area for biological conversion of toxic ammonia and nitrites to harmless compounds and the design of the Bio-Scrubber Cartridge allows for it to be virtually clog-free. The Whisper EX Filtration Systems have the innovative technology that gives the most water contact-to-filter ratio. This will give you the ultimate in water quality, and fish and plant health.

    Theses filters are easy to replace.
    I have ordered at least 3 times and every time charcoal dust is on everything else in the box.
    These filters should be packed with some kind of barrier to keep the black dust from being on all the other items.

    Yo hacía mis propios filtros con carbon activado que me recomendarion en la tienda los profesionales, pero no daban el mejor resultado. Decidí comprar los repuestos originales para asegurarme de tener lo mejor para mis peces y desde el primer día noté la diferencia, funcionan excelente, limpian muy bien el agua y la mantienen por más tiempo en excelentes condiciones. Duran bastante tiempo sin tener que cambiarlos. Acabo de cambiar el primer filtro después de 1 mes y medio, y creo que pude haberlo dejado los 2 meses sin problema, pues no estaba tan saturado de deshechos. Los recomiendo ampliamente.
