【More Activated Carbon】16 Pack Replacement Filters for Kastty 3L Cat Water Fountain, Food Grade Water Fountain Filter for Kastty and other Cat Water Dispensers, Made of Activated Carbon and PP Cotton

Easy to replace. Water stays clear!

These worked great for my older Katsy water fountain. Katsy upgraded their fountain and pretty much stopped making these filters. When I saw these with even the second filter replacement I was so excited. They could be filled a little more inside the filter but they work great! I replace them every week and a half to 2 weeks! Will def buy again!!!!

Those filters are thr best

It probably works. I haven't tasted the difference after running water through it myself, but it seems to help keep the water in my cat fountain fresher for longer and the cats drink it up. Good amount for a somewhat decent price. Lasts about a month per filter for 3 cats in one water fountain.

These are so hard to find. The companies selling the cat fountains don't seem to care what happens when their initial supply of filters runs out making their fountain useless. Thanks to the sellers for making this needed quality product available. *5* Stars!

Works very well

These are great replacement filters for the listed water filter. No issues.

I like these ones better than what my fountain came with. Only problem is the replacement sponge filter is crap, not the right shape and doesn't fit the motor mount. And since it's squished into the package they are all flat and dont expand so I have to just wash the sponge my fountain came with.
