PK.ZTopia 8-Pack Cat Water Fountain Filter, Pet Fountain Filters, Replacement Filters for 84oz/2.5L Automatic Pet Fountain Cat Water Fountain Dog Water Dispenser

They work well

These filters are easy to change, and they do work. I was skeptical but then saw after the first use that the filters really do work. Each filter lasts longer if you only have one cat and if you place the water in an out of the way place. With more cats you will need to change it more often. I have one cat and each filter will last for several weeks.

Cheaper than the brand named ones, work just as well.

They do what they need to do. Purrrr

It works great

Does exactly what you need it to do. Filters the catss water in our Vekken fountain. Typically last for 3 weeks until it starts to get gunny again. Can reccomend.

Have to replace too often

One of them was missed.

These filters and water fountain saved me and my cats lives lol. Literally cleaning the fountain is so easy and changing the filter is much needed and having these on amazon are so convenient for my fur babies!

Great for cat water fountain
