Tomxcute Cat Water Fountain Filters for 108oz/3.2L and 135oz/4.0L Adjustable Water Flow Pet Water Fountain，Ultra-Quiet Cat Water Fountain Dog Water Dispenser 8 Packs Filters & 8 Sponges Foam Filters

These charcoal filters have almost no charcoal. They turn green in four or five days. Theyre absolutely pointless. Youre just throwing your money in the trash. If you can return the fountain that you get these filters for, I would recommend doing that as well because you cant find any filters that actually have charcoal in the charcoal filter that fit this particular fountain. Its absolutely theft.

They are prompt and will right any problem. I have 4 water fountains and they are great! Worth the expense!

This is a good bargain for your kitty. It keeps the water fresh and the your cat drinks more water and stays healthier. Definitely recommend getting these together with your cat water fountain.

Its very quiet, very easy to clean and holds a lot of water. I just wish it had a low level indicator

Quit working after one week. Maintained water level as per instruction. It was a great product for a SHORT time.

We bought this because the last fountain we had slopped over the sides and created a problem on our wooden floors. This one does not do that. It is easy to clean, completely quiet and most importantly - our dog and our cats are VERY happy with it. Very good quality!

Missing parts and never received replacements

This product is for my cat. She drinks out of it all the time. Easy to maintain and quiet!

Very easy to switch out filters.

They say you should replace these filters once a month- they don’t even last 1 week! I’m glad I checked when refreshing the water, the filter was already gross after a few days! I’ve only been using it a few weeks and I’ve gone through 3 filters, I hope a find a better replacement filter for this model otherwise the whole foundation is junk.
