HiTauing 6 Pack EF-S Filter Cartridges for EF-S Element and BF5 BETTAFLO

We have Top Fin aquariums for our betta fish, and these filters work perfect, so much more inexpensive than going to your local pet store, we were spending $15 for three cartridges and for less than $10 you can get six this just works out fantastic and they fit and work, this is for a Top Fin filter that's a size small I think it's EF small

Great value and word great in my filter. Very durable and easy to clean. Amazon home delivery was very convenient

Great filter at a reasonable price! Great for my small goldfish tank and so happy I found them online!!

The filters were the correct dimensions and other than the fact that the plastic tab needs bent inward the filters are good.

does job well.

This product is great as you can see it keeps the the water really clean

The filters are exactly what my tank requires and they are priced reasonably.

They are ok

For the small split aquarium of 2 Beta fish- perfect filter. The box will be enough for probably another year or two

I’ve bought these a couple times now. They seem to do the trick keeping the tanks water clean. I’m able to wash them during tank cleanings to stretch out the life time of them. I don’t know if it matters but there is only one fish in the tank.

Size is accurate but.. a little nervous to use as the box the filters are in was dusty and dirty, and upon opening the box, none of the filters are wrapped in any sort of protective packaging, which leads me to believe they were stored in a dusty environment which is probably now in the filter was well..

Says it would fit my filter but they were all too large and half of them were broken.

Definitely better filters on the market. These are noticeably thinner than the ones I got from the pet store. This is causing me to have to clean the tank more often. I will use them up but will not buy them again.
