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

These fit our childs aquarium at a reasonable price considering how often they have to be replaced.

Quick service and good price

The value for money of this is what a deciding factor in my purchase

It says that this is a one year supply for this type of filter, only most the fish tanks that use this filter take two at a time which cuts this down to only a 6 month supply.

I have one betta in a 3.5 gallon tank. My filter takes two cartridge and I change them out at every cleaning, which is about every 4 weeks. The filters hold up well and actually dont look that soiled at 4 weeks but I change them anyway. I purchased my first box of these back in June 2021 and now on my reorder received the same product.

Have yours these filters for over 2 years and Amazon ordering made it easier

Filter works as it is supposed to. Satisfied.

Easy fit value pack .

Lasts a month or so

Super Easy to replace
