#1 Vet-Recommended Cat Hydration Device
AquaOne uses a sealed source design — clean water and used water are physically separated. The pump sits inside the sealed clean tank and only ever touches fresh source water. Every 6, 8, or 12 hours the bowl automatically drains and refills from the sealed clean source. No recirculation. No contamination cycle.
Every other fountain moves one body of water in a circle — bowl, pump, filter, back to the bowl. It looks like it's moving. It isn't getting cleaner. Fresh water on a schedule beats moving water that's been recycled since Tuesday.
Every other fountain on the market recirculates the same body of water through the bowl, pump, and filter. Saliva, hair, and bacteria re-enter within seconds of your cat drinking. AquaOne's Sealed Source Design means the water your cat drinks has never been contaminated. The drinking surface is 304 stainless steel — no plastic chin contact, no chin acne pathway. Fresh water delivered on a schedule means your cat always has a clean surface to drink from.
Weekly (under 5 minutes): rinse the stainless drinking tray, wipe the head unit with a damp cloth.
Every 3 months: run a vinegar-water rinse through the system for descaling. No 25-minute disassembly. No little brushes. No vinegar soaks that don't work. The auto-drain and auto-refill cycle removes the daily lifting and scrubbing traditional fountains require.

Most cats start within 24–48 hours. Place PureStream next to their current bowl for 3 days, then remove the old one. If your cat doesn't take to it, you're covered by our 30-day money-back guarantee — send it back, full refund.
No — and that's the point.
AquaOne isn't a recirculating fountain. It fills the 304 stainless steel tray with fresh water, then completely empties and refills it from a sealed clean tank every 6, 8, or 12 hours — whichever you choose. Between cycles, the water sits still.
Traditional fountains keep the same water moving in a loop, and that loop is exactly how they go wrong: your cat drinks, saliva and hair go back into the bowl, through the pump, into the filter, and back out again. The water looks like it's moving. It isn't getting cleaner.
AquaOne gives your cat still, genuinely fresh water instead of moving, recycled water.
If your cat specifically needs to see water moving to drink, this isn't the right product for her — and our 30-day guarantee covers you if that turns out to be the case.
Every other fountain on the market recirculates the same water through a submerged pump 24/7. That pump builds biofilm (the slimy gunk) within days, contaminates the water your cat drinks, and is the #1 cause of fountain failure. PureStream's dual-chamber design dispenses fresh water from a sealed tank — the pump never touches dirty water. No biofilm. No constant noise. No filters.
No. PureStream doesn't use filters — ever. Owners of filter-based fountains spend $60–$120/year on replacements. With PureStream, that's $0. The dual-chamber design keeps water clean without needing one.
Silent. Most fountains run a pump 24/7 — that's the constant hum that drives owners (and cats) crazy. PureStream only activates briefly to dispense water, then goes back to zero noise. No background hum, ever.
Every 10–13 days for one cat. Every 4–7 days for multi-cat households. (Compare that to daily top-ups with most recirculating fountains.)
Once a week. Under 5 minutes. Wipe the stainless steel drinking tray, empty the waste tank, done. No pump to disassemble, no filter to swap, no biofilm to scrub.
Yes. The drinking tray — the only surface your cat's whiskers and chin touch — is 304 food-grade stainless steel. The reservoir is BPA-free plastic and stays sealed: water only meets the tray when dispensed. No plastic taint, no chin acne risk.
Yes — but most multi-cat owners do better with two. Cats drink more when there's a fountain on each level of the house, and some cats simply don't like sharing a water source. One PureStream handles 1–2 cats easily (2.6L sealed reservoir, refill every 4–7 days). For 3+ cats, or homes with cats on different floors, we recommend two — one upstairs, one downstairs.
About 15 days per charge — the pump only runs during the refill cycle, so nothing draws power in between. No cord to hide, either: unlike AC-only fountains, AquaOne runs on battery, so it goes where your cat actually drinks rather than wherever the outlet is. Recharge about twice a month, or leave it plugged in if you prefer.
30-day money-back guarantee. If your cat doesn't take to PureStream — or you're unhappy for any reason — Contact us within 30 days and we'll make it right. If anything is faulty we replace it free, and you keep the original. If it simply isn't for you, we'll agree a refund — and because we can't hygienically resell a used fountain, you keep that too. Plus a 1-year warranty on the fountain itself. We engineered out the #1 cause of fountain failure (a pump submerged in recirculating water), and we stand behind it.

The kitties have taken quickly to the new watering hole. Love that they are always drinking clean water. Thumbs and paws up!
I love not having to deal with that slime that the other fountains had after 3 days. I only have to clean the metal tray. I like the idea of separate water, one for clean and one of dirty.
Our female car loves her new water source. We put it next to her window bird feeders .
At first I was sceptical but this fountain has actually been really great! It did take my old little man about 2 + weeks to get used to it. He scares easily with funny noises like this fountain makes when emptying and refilling. He has really come around to it though and I think he loves the fact that he can sit with his head more upright. The ONE complaint I have is that my cat drinks a LOT and the top bowl will become empty long before the refill time occurs. I wish in that regard that the sensor would refill sooner than the scheduled timer or sense that the stainless steel bowl was empty/dry.
Freddy likes that he always has fresh water now
I love the concept of this fountain and one of my cats loves it too. The problem is I have 3 cats, and one won’t drink from the fountain because no water is moving, the second one will only occasionally drink from it and still ask for water at the faucet and the third one loves it. I would love if there was a way to recirculate the water in the drinking dish, but have been told that’s not an option, though I’ve seen videos/pictures showing a version of the fountain doing that.
Excellant and my two cats love it.
Setup was easy and after a couple days of acclimation, my cat has no issues drinking from it. I feel much better knowing that she has a consistently cleaner supply of water now compared to her previous fountain. I only wish I knew about this product sooner.
Shortly after setting it up my cat was drinking out of it. As advertised it works well and it is easy to clean. With one cat the fountains goes 5 to 6 days before needing to fill it. It took a fairly long time to get it, but well worth the wait.
I really like this fountain. I feel good knowing that my kitties are getting fresh water. It’s super easy to clean. I take it to the sink and wash the stainless steel plate in warm soapy water, rinse out the tanks and fill it up again. My kitties know the sound of it draining and filling up and they come running. I have three kittens and I find myself cleaning and refilling it about every two days. I’m know I should have another one but I can’t quite manage that right now. I highly recommend this fountain.
Works perfect. Motion sensor picks up my cat every time and only runs when needed.
The dual tank design is honestly genius. When I emptied the wastewater side for the first time I was shocked how much stuff was in there.
My dog keeps splashing water everywhere with normal bowls. This has cut down on the mess a lot and seems to encourage him to drink more.
I was skeptical at first but my cat started using it right away. I really like how the clean water stays separate because my old fountain would get gross so fast. Easy to set up too.
My cat Milo is picky about water and usually prefers the sink. Since getting this fountain I've caught him drinking from it multiple times a day.
Great product. Battery life has been good so far and I like not having another cord running across the floor.
Love this fountain. The fact that I can see the dirty water collecting separately is honestly what sold me. Makes me feel better about what my cat is drinking.
Nice size reservoir. We left for a weekend trip and there was still plenty of water left when we got back.
I have three cats and they all use it. I was worried they wouldn't share but it has worked out great. Very happy with this purchase.
Very impressed. The clean water side stays fresh and I don't have to mess around with replacing filters all the time.
Super easy to charge and get going. Took maybe five minutes from opening the box to having it running.
One of the things I love most is how quiet it is. It's in my bedroom and I barely notice it.
Easy to put together and easy to clean. My cat Luna usually ignores fountains but she keeps coming back to this one.
Works exactly as expected. Very quiet and my two cats figured it out within minutes. The motion sensor is a nice touch and saves battery.
Very useful routines for my animals. Keeps the water clean and purified. Eays to remove and clean the bottom portion and top portion without any hassles. Built in filter is such a huge game changer. Not overly huge and fits nicely next to their food bowls. Overall recommend for any pet owners.
My cat took to the fountain right away. The only thing that is spooking her is the sound when it dumps the water and refills. She is 16 years old with kidney issues. I am hoping 5his is the healthiest fountain for her.
Cats love it and we see big difference
My cats took to this water fountain right away. We have 3 cats, and are finding we have to have it cycle every 6 hours (middle setting) as they have been drinking it dry before it is ready to cycle again. But much better not having to deal with slimy filters every couple of days. I really didn't think it was good for them to drink that dirty water and think seems to solve the problem.
After 2 weeks of cautious "stalking" the water fountain was deemed to be "not dangerous" and the cats have all now determined that it is wonderful to have fresh flowing water whenever they need hydration.
My husband and I are very impressed with the fountains. (We bought 2). They are quiet, and our cats (all 3) like them. All are drinking well which did not happen with previous fountains. Love that they are cordless.
Had a little problem with the water not staying in the pan but I must say support help me immediately and I was able to solve the problem. As far as cats loving it I have two water fountains and two cats they love it.
I love the Purestream Fountain for me. It is so easy to clean and no filters (that's the best part)! I have not yet seen my cats drink from the fountain but I think they do drink when I cannot watch them so I am unable to say they like the fountain. But, I certainly do!
Both of our cats took to it right away. This really does make the "water bowl" experience much better for our cats and us. Having the mat for the unit is also a great help as one of our cats can be a bit messy when he drinks. Thanks!
Absolutely satisfied beyond belief with this innovative product — what took sooo long to bring a wonderful product like this to the market. We bought two … one for each level of our two-story home. All three of our cats love these fountains … and ‘took to them’ immediately. It was like they knew that they were going to be receiving/ drinking clear, fresh water with every sip! WINNING!!!
I do believe the cats drink more water
Our cats live it. Easy to use and take care of. We are 100% satisfied,Thank you Joseph
Easy peasy to deal with and even catch my cat using it way more often than ever before! Smart design, quiet operating, and easy to maintain!
So far so good. The whole concept is refreshing!
The water is cleaner for sure . I like that it dumps the old water . I set mine to dump the older water every 6 hours It’s working good
Took a long time to arrive and in between I lost my little kitty but I have a small chihuahua and he loves it! Very easy to set up and use. Gives me peace of mind knowing his water is clean all the time. Definitely recommend!
