Top Fin Retreat RF-S Filter Cartridges (Small) Refill for Desktop Aquariums with Small Retreat Filters - 8.1in x 1.9in (6 Count)

Its perfect size and exactly what we needed. No complaints.

Works well fits well does the job

Bought for grandaughters fish tank

Same filter that filter pump came with new. Good replacement filters.

More than likely one of the best filters in the market ! Great for one month at a time

This box of Topfin filters is about $13 for 6 filters through Petsmart. This is a ridiculous price youre charging.

Works great for the filter. Easy to change cleans the tank flawlessly

I love that came quick and is great doe that price

I love them they keep my fish safe. Thank you top fin

The product itself is great but came in a destroyed box. Thankfully the filters look to be intact
