Top Fin Silenstream PF-S Small Filter Cartridges (6 Count) Refill for PF10 Power Filters (5.5in x 3.1in)

Good

Just as described, these last about 3 to 4 weeks for me.

Great value

No issues. Filters do the job as designed.

perfect filters for small tank

Great product

Worth the money and lasted for almost a month.

Our Petsmart store closed so I was happy to find this as its the only kind my filter will use. I love these as they are long lasting even in multi fish setups.

Couldn’t find them in store, so got there here. Absolutely worth it!

They go in a fish tank!
