Tetra® Whisper Bio Bag Cartridges
Whisper Bio-bags are so convenient.
I have been using Whisper bio-bag filters with my fish tank for the last 20 years and find their ease for changing so easy. You can easily see when they need to be replaced.

Not bad for the price
I wouldn't call this the best filter on the market, but considering the price investment, it does a pretty good job. For a small tank, there aren't many options that don't create a turbulent environment for fish. This one has a nice, gentle flow. My betta is quite pleased with it. Filters are easy to change and inexpensive too.

Good for its size!
Perfect for a small tank. I use it in one of my betta hospital tanks and its perfect for it. First day I set it up and the water was already clear. Doesn't make any loud noises, very small, and it doesn't rip or hurt my bettas fins. It was also very easy to set up. Had some difficulty with the air line because it was a bit small but I got it to fit.
