How AquaOne Works

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.

Why It’s Better for Cat Health

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.

Cleaning & Maintenance

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.

The Problem

That Slimy Film Inside Your Cat's Fountain?

That's What Your Cat Is Drinking.
It's Serratia marcescens. It lives behind your pump, inside the filter housing, in crevices you can't reach. Cleaning the bowl doesn't fix it.
Other fountains share water between the bowl, pump, filter, and cat, allowing saliva and hair re-enter. Carbon filters don't reduce bacteria. They host it.
The pump only ever touches clean source water. The drinking surface refills from a sealed source every 24 hours. The slime never starts.
Why PureStream

We Didn't Redesign The Cat Fountain. We Started Over.

Every other fountain on the market shares one body of water between the bowl, the pump, the filter, and the cat. AquaOne uses two physically isolated sealed chambers, and the pump never sits in the water your cat drinks from.
*Tap a point below to learn more

Sealed Source Design,
physically isolated

2.6L sealed clean source. 1.35L sealed wastewater. The cat never accesses either. The drinking surface refills from clean source every 6, 8, or 12 hours - every drop sealed until the moment
she drinks.

Pump never sits in
dirty water

Sealed inside the clean-water tank. Only ever touches clean source water — no hair, no saliva, no biofilm. Other pumps die because they sit in what your cat drinks from. Ours never does.

No chemical filters. No carbon. No bacterial substrate

Clean tank → drinking tray → wastewater tank. Water flows one way and never loops back — nothing to filter, nothing to recirculate. Unlike every other fountain on the market. No cartridge tax. No bacterial colonisation.
How To Use AquaOne

What Ownership Actually Looks Like

Daily

Battery lasts ~15 days per charge. The pump only activates briefly during each scheduled refill. Silent otherwise. Below 25 decibels when running.

Every 6, 8, or 12 Hours

The bowl water dumps
automatically and refills from the sealed clean source. You don't do anything.

Weekly

Rinse the stainless drinking tray. Wipe the head unit with
a damp cloth.
No 25-minute
disassembly.
No little brushes.

Every 3 months

Run a vinegar-water rinse through the system for
descaling. Done.
The auto-drain and auto-refill
cycle removes the daily lifting and
scrubbing that traditional

fountains require.
For
owners with mobility

limitations, this is

what makes a fountain

actually workable.

You Threw Your Last
Fountain In The Bin. We Get It.

You've tried PetLibro. Catit. Maybe Drinkwell. The pump died. The slime came back. Every other fountain on the market has the same three design flaws built in. AquaOne solves all three.

"I couldn't believe the difference. My cat walked straight up to it and hasn't stopped drinking since. She used to barely touch her old fountain but now she's at it multiple times a day. Worth every penny."

"Finally a fountain that doesn't take half my Sunday to clean. Rinse the tray, rinse the sponge, done. My last fountain had parts I couldn't even reach with the little brush they gave you. This is completely different."

"With my old fountain I was finding pink slime within days no matter how often I cleaned it. I've had the AquaOne for two months now and nothing. The water looks exactly the same as the day I filled it."

"My last fountain sounded like a washing machine, especially when the water got low. This one is completely silent. I actually had to check it was still running. My cat doesn't even flinch when it activates."

"The fact that there's no cord is great. My old fountain had to sit right next to an outlet which was never where I actually wanted it. Now it just sits where my cat likes to drink and I don't have to think about it."

For The Faucet Cat

Your Cat Only Drinks From The Tap? We Hear You.

The faucet-obsessed cat is its own category. She'll yowl until you turn on the kitchen tap. She refuses bowls on principle.
AquaOne dispenses fresh water from
a stainless steel surface every 6, 8,
or 12 hours -
fresh, clean water
always ready when she comes to
drink.
Most faucet cats adopt within the first week.
More Than One Cat?

Two Cats. Three Cats. Four Cats. AquaOne Handles It.

Most cat parents end up with two. Here's why:
1
Cats look for water in different spots. One fountain upstairs, one down means fresh water's always close, so they drink more.
2
More than one cat? A single fountain turns territorial — the bold one guards it, the shy one quietly misses out.
3
Two means one's always running while the other's cleaned. Your cat's never left without.
Better hydration protects their kidneys and keeps them healthier as they age.
Health Concerns?

For The Owner Whose Vet Asked Her To Get The Cat Drinking More

Your vet has told you she needs more water. Maybe she's senior.
Maybe she's been diagnosed with CKD or had a UTI. You want her water
to be clean, fresh, and available when she goes to it.
Owners in the same position consistently report greater peace of mind once the daily refill chore stops being theirs.

Frequently Asked Questions

Will my cat actually drink from it?

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.

How is PureStream different from PetLibro, Catit, or PetSafe?

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.

Do I need to buy replacement 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.

How loud is it?

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.

How often do I refill the water?

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.)

How often do I clean it?

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.

Is it safe for my cat? (Materials & health)

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.

Will it work for multi-cat households?

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.

How long does the battery last? Do I need to hide a cord?

One handles it, but two is better. Cats drink more when there are multiple water sources around the house. A second unit in a different room means every cat always has fresh water nearby, regardless of how many you have. Most multi-cat households find two the sweet spot.

What's your guarantee?

30-day money-back guarantee. If your cat doesn't take to PureStream — or you're unhappy for any reason — send it back for a full refund, no questions. 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.
