I exclusively use these for my aquarium. They filter very well and hold the charcoal without it leaking out. They also last approximately 6 weeks before needing changed. I will take it out on occasion and rise the outside and put it back. Works like a charm. I've tried others, however they weren't as effective. I get mine at the local pet store. I will only use these for my fish.

These are my go to filters. I love them because you can just rinse and reuse them a few times before replacing them which saves tons of money. Highly recommended!

I love the whisper filter system! I had a different brand when I first bought my turtle and the dang thing made sooo much noise I found my self having to turn the TV up to drown out the noise. but the system lives up to its name--whisper! I love the cartridges too I only have to change them like every 2-3 months and I never had an issue with murky water or a smelly tank

Good for the price. It helps keep the water clear. Max I'd use this for would be 20gallon tank. After that I would move up to a canister filter. This brand is good for tanks with the correct amount of fish for the tank

This 12 pack is a lifesaver and has lasted such a long time. I will definitely be repurchasing this product from Amazon. It has everything you need for your Whisper filter and is so simple to use. The price is also great!

I used these when I had four turtles and I thought they worked really well! It really got all the dirty and whatnot, it kept it to it - it didn't come off and float in the water.

I have a 40gal tank for a red eared slider and she gets so yucky. But when I have in a filter with these cartridges, it makes such a difference. Last a long while, but it can be a messy clean up.

This works wonderful. I have a Chinese water dragon and it helps clean the cage for weeks. I love these and my new filter. I did not know how I would feel about this until they came with my new

I actually use these in a non tetra filter unit because I know the bio bags work so well.
My 10g tank stays clean for weeks with 2 nasty gold fish.
Anyone that has goldfish know that they are messy!
