So convenient to use. What can I say? Take the dirty filter out and put a clean new filter in! It's just that eazy. I do this once a month. And I have very happy fish and a clean clear fish tank.

Seems like I go through them a lot, which has to do with the pump I suppose. They're a little fat, so sometimes don't fit in the groove easily.
Good product & price

My first one that came with the filter got absolutely disgusting. I found these at the best possible price including shipping fees. I love ordering from chewy! These are so overpriced at pet stores near me it isn't worth going to pick them up.
Easy to use

I love that these come already assembled. Makes them so easy to use. You just rinse them off and put them in the filter. That's it! Not complicated at all.
Happy to find these!

I was having a hard time finding these at my normal location. Chewy to the rescue! Reasonably priced and perfect for our African Aquatic Clawed Frog's tank.

I love these filter cartridges. I have been using these for about 15 years. I have red eared sliders and these are my go to filter cartridges.

Works great in my filter, fully assembled, in a sealed bag in the box.
Package was damaged
on Sep 6, 2020
Whenever I opened the box the filters were already opened and damaged. Some of the inside of the filters was out and made a mess. I inspected them and they seemed like they had no damage. But was surprised the filter box was already opened.
Convenient package size

Chewy has good prices and acceptable delivery time. But in the few times I have used them, some of the product inside the box has come smashed.
