Tired of scrubbing that "yucky" film off the tank? The PETKIT Fountain Cube C slows down slime buildup by 30%, keeping surfaces feeling cleaner for longer and significantly cutting down your deep-cleaning chores.
Change in a snap.
Maintenance shouldn't be a project. Simply pull out the old core and push in the new one. No tools, no disassembly, and no mess, just a 3-second swap that gets you back to your day.
A fresh month, guaranteed.
Most filters quit after a few weeks, but this cube is built for the long haul. It provides a full 30 days* of consistent, high-speed filtration that works just as hard on Day 30 as it did on Day 1.
*Testing conducted by a third-party laboratory.
Always in the loop.
The PETKIT app tracks the exact lifespan of your filter cube. Check in anytime for real-time updates, and receive an automatic reminder when it’s time for a fresh swap.

FAQ
What is Fountain Cube C?
Fountain Cube C is a structural component that sits at the water outlet of Eversweet Ultra. It helps to inhibit biofilm buildup, keeping water fresher for longer between cleans.
Does EVERSWEET ULTRA work without Fountain Cube C?
Fountain Cube C is part of the fountain's structure and must remain installed at all times. One Fountain Cube C is included in the box.
Do I need to replace it?
Replacement every 30 days is recommended for optimal water quality.
How do I know when to replace it?
We recommend following the 30-day schedule for best results. The PETKIT app will also send you a reminder so you never have to think about it.
Is Fountain Cube C the same as a filter?
No. Most fountains require a filter to function. Fountain Cube C is a built-in structural component that adds a layer of freshness protection. The OneWay Mechanism is what keeps water clean by ensuring it never recirculates. Fountain Cube C simply enhances that further.
Great product! Well worth the money spent. No more slime! It cleans itself, refills with clean water. You can set that at any time. The cube filters are great and cheap! My cat absolutely loves the fountain. It is quite, but moving. I have no complaints at all. Definitely worth the money spent.🐾🐾🐕
Hi there, thank you so much for your wonderful review! We’re thrilled to hear your cat loves the fountain and that you’re happy with your purchase. Enjoy fresh water and less hassle!
I absolutely love this fountain. The camera lets me check in on my cat while I’m away, and it’s really reassuring to see that they’re actually drinking water. It’s super quiet, easy to clean, and the app is simple to use. Definitely more expensive than a regular fountain, but for me it’s been worth every penny.
The cube is great. Just need to modify the bowl on the fountain. My high maintenance Persians go to the water fountain, which I have two of. I took one away to get them to use this one. They bypass it. Especially my two boys. The bowl needs to be shorter in the area where they are standing to reach over. They seem to rather drink out of a bowl on the other water bowl, which also dumps the water into a separate bowl and refills. The cube is just fine. I will look into the special cubes, can you make an all in one? The one for uti, bladder stones, fur balls, all that is needed.
It’s just my 4 Persians don’t seem to care about reaching down over the wall, they love how the other is designed to drink out on their face level. Also I love the camera it’s awesome and I love the fountain part, it’s actually too quiet. They need to hear a noise lol
With this fountain i can know which cats drink water or not and can check the camera around there too , can see the cats and what they do . I love it. It’s easy to clean and don’t need to buy filters anymore. I bought a lot of products from PETKIT and will be supporting them in the future
CATS ENJOY SEEING THEM SELFS AND DRINKINF FREASH WATER
I've tried a few pet fountains over the years, and honestly, I thought they'd all reached the point where there wasn't much left to improve. Turns out I was wrong.
The PETKIT EverSweet Ultra does something that made me go, "Why hasn't anyone done this before?" Instead of endlessly recycling the same water, it keeps fresh water coming into the drinking tray while the used water drains away. It's one of those ideas that's so obvious once you see it that you wonder why every fountain doesn't work this way.
I also didn't think I'd care about the camera, but now I check it way more than I expected. It's fun catching my cats sneaking over for a drink, and it's actually pretty useful to know who's drinking and when. If you have more than one pet, it's surprisingly nice to see their habits without playing detective.
Another thing I appreciate is that it doesn't feel like it was designed by someone who enjoys making cleaning difficult. Taking it apart is straightforward, and the automatic flushing feature helps keep everything fresh without me having to constantly think about it. Less scrubbing, more couch time.
My cats took to it almost immediately, which is probably the toughest review that matters. They drink more often, and I have a little more peace of mind knowing they're getting fresh water instead of the same bowl circulating all day.
Is it the cheapest fountain out there? Definitely not. But it also doesn't feel like just another pet gadget with Wi-Fi slapped on it. There are actual thoughtful improvements here that make a difference day to day.
Bottom line: my cats are happy, I'm doing less maintenance, and I get to spy on them being adorable once in a while. I'd call that money well spent.

It’s the BEST PET WATER FOUNTAIN EVER in my 25 years live with dogs.
Love not having to get filters anymore! Instructions could be better but no biggie I got it figured out. Camera is excellent
Fountain Cube C
I have used quite a few fountains, this is the first one my cat has refused to drink from.
Hi there, we’re sorry your cat hasn’t taken to the fountain yet. Try keeping their usual water bowl nearby while they get used to the new fountain. We hope they give it another try, but if you need help with a return, please feel free to reach us at support@petkit.com.
Who would have thought such a tiny thing could have such a significant effect in water quality
Love this thing and it actually works. My dog is drinking so much more water than she used to, I’m able to monitor and track her hydration, and the 5liter reservoir really last a long time, 12 days until I had to refill it. Best purchase in a while
good so far!
Makes hydration for my guys an ease. Can tell how much my guys are drinking and occasionally dropping in on them and saying hello!
I love the idea behind this product in always separating the clean and dirty water. My cat, however, isn't very fond of the new fountain. I think she is afraid of the constantly moving water. Still trying to figure out how to let her know that the water fountain is safe.
Bout in July and it’s Oct and already malfunctioning. Changed the cube. Turned it off and on. Checked the app. It keeps emptying and refilling randomly and has to be changed daily now. It is even overflowing. Too expensive to work a couple months. I had planned to buy another but now am back to the traditional drinkers. So disappointed.
Hi there, we’re sorry to hear about the issues with your fountain. Our support team is following up with you to help resolve the problem. Thank you for your patience!
I absolutely love this!!!
My cats took to it right away.
They are noticably drinking more water, and doing it more often.
This is a great product!
love it
From taking it out of the box, setting it up and my little frenchies first drunk, this thing is a breeze to use. I tried the deep clean mode, worked perfectly. It’s great peace of mind knowing our pup always has fresh water, highly recommend.
I love the cube. It’s a genius move for the water filtration system. I’m only waiting now for the other 3 cubes that do different things to ensure the health of my cats.
A major downside is the lack of a battery backup for power outages—a problem if the owner is away for a few days. This means the pets could be left without water for hours, requiring a neighbor to step in and put out a bowl of water. The dual-reservoir design is excellent. It would be helpful if the manufacturer specified which type of backup battery is compatible with this fountain model.
Hi there, thank you for sharing your feedback! We're glad you like the dual-reservoir design. We'll pass your suggestion regarding backup batteries to our team to consider for future improvements.
I really like this fountain for many reasons. Too many to list here.
I love love love this product. Less refilling as well as separated filter from drinking water.
works as advertised. awesome product!
loving my water fountain so far I do have one cat that is terrified of it so he won't use it yet. he has been getting closer to watch it, hopefully so he'll try. so can't quite get rid of my regular fountain yet.
