Whisper Assembled Bio-Bag Cartridge Large (Single) For the ultimate in convenience, choose Assembled Whisper Bio-Bag Cartridges. Like
the Ready-to-Assemble, the packages are color-coded, making it easier than ever to
remember which size to purchase.
I keep several, large fish tanks and use internal filtration in most of them. The Whisper filters are perfect for tanks that need internal filters. The filters and media are easy to clean and replace. I've found the products Entirely Pets offers are much less expensive than the chain stores even with the small shipping costs.

I am very pleased with Bio Bags. They keep my 55gallon tank crystal clear. I also like the auto shipment....That is really a plus.
I recommend Bio Bags to anyone with a fish tank, for healthy fish and an clear tank...

These are good filters, and easy to change. I hope the pumps which support these continue to be manufactured
Bio-Bagging by Bob01/26/2012
Product works well for its intended use. If you want a middle of the road filter for a very reasonable price, the Bio-Bag filters work well. It does what it is made and designed for and is very easy to change.
I'm stuck with this product/system for now by Adele from Los Angeles, CA04/16/2014
What a mess the bio bag has proven to be! I am stuck with it because I unknowingly bought a filtering system for my 5 gallon tank that requires this. You have to make up the filters yourself, and try to pour the little bits of charcoal in without spilling them all over the place. I would much rather purchase a pre-fab filter that won't make a mess of things. When this filtering system dies, NEVER AGAIN! I will ad, however, that entirelypets.com did an excellent job. Product was delivered quickly, and in excellent condition.
Best prices I have found by andi from cape cod,MA12/01/2012
These unassembled bio-bag cartridges are just as good,if not better than the much more expensive pre-assembled bags.
They work really good in my turtle tank filters.
serves it's purpose by ndonsomd from md04/30/2014
We use these bio bags with a whisper filter in our aquatic turtle tank. We use two filters and they server their purpose. We like these because we can reuse the plastic part of the filter and it reduces waste.
Good purchase by Dulcinea10/27/2012
These filters are easy to assemble and work as expected.
good product by bobe from Charlotte, NC05/05/2012
the product is much cheaper than the pet stores because you have to do a little assembly yourself. very simple to assemble, definitely worth it for the savings.
great product, use them all the time by football88 from carthage, n. y.07/30/2013
This is the best available product on the market since the demise of the more expensive (and more efficient) product to do the job of filtration.. I would have liked more to the box, perhaps six or eight, to save some money, but this is the only number of cartridges in a box on the market.
Bought this to replace the in-tank filter that came with an aquarium setup. Followed instructions for setting it up to the letter. After 2 days, noticed the level in the tank had dropped about an inch. Topped it off. Next day, 2 inches. Finally discovered it leaking from the pump assembly. Removed pump assembly (per instructions) and reseated o-ring. Worked fine for a week then the water began disappearing again. After the 3rd occurrence, the filter went in the trash. Glad I kept the one that came with the tank...
