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

4 stars because filters where shipped in a bag and the box of filters got squished. Should have been packaged in a box. Thank goodness item was not damaged. Other than that ordering was easy and item was delivered in a timely manner.

Fit right

Works well.

It’s a fish tank filter

Good

Needed these last minute. They arrived fast and were perfect . price was better than the store .. Atleast for me . I Will probably reorder from here :)

works very well

This is the correct filter refill for my tank. It fits. It works. Price is a little higher than buying from a chain pet store.

This is double the price at Petsmart and is price gouging . The filter itself works fine

Exactly what we needed for our fish tank.
