These are great filters. Chewy is one of the only places I can find these filters
Can these work on any aquarium filter

I at first was looking for a double type cartridge for my top fin 5 gallon filter, but i was wondering if these would work just as well for my filter or does it only work for a tetra whisper filter? And btw everything I have purchased from Chewy have been best quality & great prices. Thank you
Wahoo! I couldn't find XS anywhere.

I have a hard time finding the extra small. And if I did find them it was only a package of 2. So I was very happy to see that you had them.
