The First Filterless Fountain
The only official HydroPurr Fountain, beware of lookalikes on Amazon & other sites.
Our HydroSplit™ design uses two sealed tanks, so nothing ever gets recycled. Clean water sits in a sealed 2.6L (88oz) reservoir, and a built-in pump that only ever touches clean water sends a fresh pour (about 50ml / 1.7oz) to the stainless-steel tray on a schedule you set. Used water then drains away by gravity into a separate tank, carrying fur, saliva and crumbs with it — so it never loops back to your cat.
Most cats take to it within a few days. Running water naturally draws them in, and the low, wide stainless tray is gentle on whiskers and chins. For an easy switch, set HydroPurr beside their current bowl for three or four days, then remove the old one. Some dive in the first night, fussier ones take a little longer — both are normal, and you're covered either way.
Barely any upkeep — and never a filter to reorder. Refill the clean tank about every 10 days for one cat (around every 5 for two), and empty the waste tank when it's full. To clean, just take it apart, wipe with water, and air-dry. The rechargeable battery runs cordless for about two weeks per charge and tops up with the included USB-C cable.
~10 days for one cat, ~5 for two.
Take apart, wipe, air-dry. Key parts are dishwasher safe.
USB-C, ~2 weeks per charge.
Every surface the water touches is food-safe. The drinking tray is 304 food-grade stainless steel — the same grade used for kitchenware — while the body and tank are BPA-free plastic and the internal tubing is food-grade silicone. Stainless also won't harbor bacteria the way plastic bowls can, which helps avoid the chin irritation some cats get from plastic.
Food-grade, the bit your cat touches.

Food-grade, inside the water path.

Every other fountain runs on a loop: one bowl of water, recycled all day long. Your cat's saliva, fur and crumbs get pumped right back into the bowl, and the filter removes none of it. It just sits in the gunk, growing bacteria.
That's why the slime returns days after you scrub it, why the water smells off, and why no filter swap or vinegar soak ever fixes it for long, because the recirculation is the problem, and the filter is just the subscription on top.
HydroPurr ends it
No filter. No recirculation. Clean water out, used water gone, your cat drinks fresh every time.
Top up the sealed reservoir with fresh water. Walled off from the bowl, it stays untouched and clean until the moment your cat drinks.
On a schedule you set, a built-in pump that only ever touches clean water sends a fresh pour (around 50ml) up to the stainless-steel tray. No filter to pass through, so nothing dirties it on the way.
Used water drains away by gravity into a separate sealed tank, carrying the fur, saliva and crumbs with it. That one-way drop is exactly why the pump only ever meets clean water, and why your cat is never drinking yesterday's water.
No filters to buy. No slime to scrub. No daily hassle.
No cartridges to replace and no subscriptions. Save up to $80 a year.
Used water never loops back, so biofilm has nothing to grow in.
Run it cordless on the rechargeable battery, or plug it in with the USB-C cable. Your choice, your placement.
No pump hum, no gurgle. The only sound is your cat drinking.
Lift the top, give it a quick rinse, done. Key parts are dishwasher-safe.
A hygienic steel tray that won't scratch, stain, or cause chin acne.
Vet-approved to keep cats hydrated and support healthy kidney and urinary function.
We're a three-cat household and our old fountain was a science experiment by Friday. A month into this one, the water still looks like the day I filled it. Running on battery was the surprise win — it finally sits where the cats actually hang out, not where the outlet is.
Our senior boy has never been a big drinker and his vet reminded us about it at every visit. Since this went in, he stops by it all day long. At his last checkup she asked what we were doing differently — the fountain was the only thing.
Milo has murdered two fountains by biting through the cable, so cordless was non-negotiable for us. Nothing for him to chew, and the steel tray goes straight in the dishwasher. We're getting a second one for the upstairs landing.
My old fountain would get a film on top within a couple of days no matter how often I cleaned it. This one stays clear all week. Being able to see the used water collect separately is what convinced me it actually works.
I was worried a fountain would be loud or complicated. This was running in about ten minutes and I genuinely can't hear it. My cat started drinking from it the same evening and hasn't gone back to her bowl.
I was spending way too much on replacement filters that looked disgusting after a week. This has none. Refill the clean tank, empty the waste side, done. It's already paid for itself in filters I'm not buying.
Every fountain promises fresh water. Here's what your cat actually gets with each.

Your cat deserves better than recycled water. HydroPurr's no-filter design serves up fresh water every single time, no slime, no buildup, no saliva looping back. Just clean water, and real peace of mind.
Give it a few days. The usual pattern is curiosity on day one and regular drinking by day two or three, cats notice moving fresh water fast. Keep the old bowl down at first so there is no pressure, then take it away once you see her using the fountain. And if she never comes around, the 60-day guarantee has you covered: return it for a full refund.
One-tank fountains cycle the bowl water round and round through a pump sitting in it, so everything your cat leaves behind rides along, and that is where the slime comes from. Tenace HydroPurr keeps two sealed tanks: fresh water pours onto the steel tray, and what is left drains into a separate waste tank, one way only. Used water never returns to the pump, so the pump stays clean and every drink comes from the untouched fresh side.
Filters exist to fight a problem this design does not have. When the same water keeps looping, a carbon cartridge is added to mask what builds up, and you are expected to keep buying new ones, which can add up to $60–$120 a year. Tenace HydroPurr never re-uses water, so there is nothing to mask. The only maintenance part is a rinsable hair screen, and it is included forever. Filter cost: $0.
Into its own sealed tank, through a one-way drain. It cannot flow back, and your cat cannot reach it. On rinse day you just tip it out. You can watch it collect through the tank wall, which is oddly satisfying, that is the gunk that used to hide inside your old fountain's pump.
No. There is no motor running around the clock, which is where the hum of an ordinary fountain comes from. Tenace HydroPurr wakes up for a few seconds to pour fresh water, then it is completely quiet again. Light sleepers keep it in the bedroom.
A weekly rinse. The steel tray goes in the sink or dishwasher, the waste tank gets tipped out, the hair screen gets a rinse, and you are done in a few minutes. There is no motor to pull apart and no cartridge schedule to remember. Refills are just as lazy: the 3L tank runs about 10–13 days for one cat and 4–7 days for a busy multi-cat home.
Only the drinking tray, and it is 304 food-grade stainless steel, which matters if your cat is prone to chin acne. The fresh-water reservoir is BPA-free and stays sealed right up to the moment water is poured, so it never sits in open plastic.
That depends on your floor plan as much as the head count. One unit comfortably serves one or two cats. With three or more, or cats that live on different floors, a second unit usually pays off, both because the tank empties faster and because plenty of cats prefer not to queue at a shared water source.
No, there is no cord at all. The rechargeable battery runs up to 15 days and pops out to charge, so the fountain itself never has to move. That means it can live where your cat actually spends time, not where the wall socket happens to be.
You get 60 days from delivery to decide, and cat approval counts as part of the deal. If she will not drink from it, or you simply do not love it, write to the team and you get a full refund, no restocking fee, no interrogation. The fountain itself carries a 1-year warranty on top.
You have a full 60 days from delivery to decide. If your cat won't use it or you are unsatisfied for any reason, contact the team and get a complete refund. No restocking fees, no runaround.
Works flawlessly. It pours fresh water on the schedule I set, so the tray is always topped up and clean, my cat checks it constantly.
The two-tank design is genius. The first time I emptied the wastewater side I couldn't believe how much gunk had collected.
She used to splash water everywhere with a normal bowl. This has cut the mess way down and she seems to drink more now.
I had my doubts, but my cat took to it immediately. I love that the clean water stays separate, my old fountain got gross within days. Setup was easy too.
Milo is fussy about water and normally goes for the sink. Since this fountain arrived I catch him drinking from it several times a day.
Solid product. The battery's held up well and it's great not having another cord across the floor.
Love it. Being able to see the dirty water collect separately is what sold me, I feel a lot better about what my cat's drinking.
The reservoir is a good size. We went away for a weekend and there was still plenty of water when we got home.
I never realized how dirty normal fountains get until I switched. Seeing the wastewater kept separate makes a real difference.
Our senior cat doesn't always drink enough, but since we switched she's been drinking noticeably more.
Great quality, feels sturdy and well built next to the cheaper fountains I've tried before.
Love that it works plugged in or cordless. I started in the kitchen and moved it to another room with zero hassle.
Really practical design. Cleaning takes a fraction of the time my old fountain did.
Had it set up in ten minutes and my cat was drinking from it that same night. No complaints.
The water genuinely stays clear between refills. My old one grew a film on top within two days.
No filter to keep buying, and it already feels like it's paying for itself.
So quiet I forget it's even on. My last fountain hummed annoyingly all day.
Emptying the waste tank is oddly satisfying and a bit gross, you really see what your cat's no longer drinking.
Both my cats warmed to it faster than I expected, usually one of them is wary of anything new.
The battery lasted far longer than I expected before needing a charge. Nice not having a cord near the water.
Cleaning is so much easier with no filter or pump to dismantle. A quick rinse and you're done.
Set the dispense schedule once and forget it, fresh water shows up like clockwork and I refill far less than with my old fountain.
My vet kept pushing me to get my cat drinking more, and this has honestly helped.
The stainless bowl is a great touch. My old plastic one always felt slimy no matter how often I cleaned it.
I worried it'd be loud or fussy. It's neither, it just works, and the water looks clean.
