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

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

I like the way these filter, filter out the junk that doesnt go back into the water.

Bought a 12 pack for the year, but the filter system to the fish tank I have is not as powerful as most, so Ill need to replace them 2X a month instead of once a month. Holding up ok for that time.

Great Value.

Perfect fit for the aquarium

I just got my betta fish and the filter I got was the Top Fin filter and they said I may need to get a different filter next month because these were on back order and she didn’t know if she could even get them for me. One little search on here and I found them! And definitely Big Bang for your buck!

Costly but just the right size.

Exactly what I wanted

They work nicely on the small fish tank I have, but I do have to change the filters 7-10 days

Great product. Quick shipping.
