Top Fin EF-S Element Filter Cartridge Value Pack 12 Month Supply 2.1 in X 3.7 in

Good product.

This was a perfect fit for my new 2.5 Gallon tank . Very quiet and we be easy to clean and change. Thank you for having these available to purchase here on Amazon!! Delivery was great and convenient!!

Great product. Quick shipping.

Overpriced but always sold out of stores so worth the convenience.

Fits well and keeps the water clean

My package came slightly damaged and squished in the bag. The box is damaged and the item inside is fine.

They filters work ok but should be priced a little cheaper.

Sheerness, thickness, great quality and value and money priced equally!

These are the same ones I get at the pet store but it’s more quantity than offered. there so less visits to pet store.

Fits and works as expected for our 3.5 gallon tank
