Clean water.
Every second.
Every day, 18 hours of UVC sterilization — far more than typical fountains — with no dead corners and no silicone for bacteria to cling to. Clean enough to check for yourself, and confident enough to sit on the counter every day.
The key difference
3 hours on, 1 hour off — around the clock.
UVC only sterilizes while it's on — so daily runtime is everything. To save power, most cordless fountains skip UVC entirely; the few that include it run for about an hour. Even corded models max out at 8 hours a day.
Mattte runs on a 3-hours-on, 1-hour-off rhythm around the clock — at least 18 hours of UVC a day. It's the biggest difference between Mattte and everything else, and the reason biofilm never gets a foothold.
Zero dead corners.
Bacteria collect wherever parts meet — snap-fit joints, the filter tray, the tank. The hardest spot is the tank's 90° base corner, a seam no brush can fully reach.
Mattte's tank base is one continuous curve, built for a single purpose: to be cleaned completely. The whole unit comes apart in three seconds.
No silicone — by design.
Almost every fountain routes water through silicone tubing — hidden or exposed. Silicone looks smooth, but under a microscope its surface is full of micro-pores: a perfect place for biofilm to take hold and grow.
We removed every silicone part and replaced it with food-grade PP — non-porous, smooth at any magnification. No pores means nothing for bacteria to grip, and nothing to grow on.
Four layers of filtration.
Coarse sponge and fine filter cotton catch hair and debris first. Next, activated carbon and softening resin alternate in a quartered disc — absorbing residual chlorine, odour, and impurities while softening the water.
Your pet's kidneys are more sensitive than you'd think — cats especially. Extra sodium, taken in daily, is an invisible burden. Most filters on the market don't say so, but they often use a sodium-form (Na⁺) resin that adds sodium to the water. Water soft enough for humans isn't automatically right for a cat, every day.
So we chose a formula that adds no sodium — hydrogen-form (H⁺) resin from the UK brand Purolite, certified to NSF/ANSI-61 for drinking water safety in the US. One less thing for your pet's kidneys to carry.
A quick note on how it works: standard softening resin is sodium-form (Na⁺) — it releases sodium ions to displace calcium and magnesium, softening the water while adding sodium to it. Weakly-acidic hydrogen-form (H⁺) resin releases hydrogen ions instead (which become CO₂), never putting sodium into the water. That's the mechanism behind "adds no sodium."
Design
Built to be seen.
Most pet fountains are designed to be hidden away. Mattte does the opposite — a ceramic-coated stainless top plate and quiet, matte lines, at home on the same counter as your kettle.
A double-walled tank and ceramic-shaft pump keep it steady at 30 decibels — quieter than a whisper, safe for the bedroom.

FAQ.
UVC light only sterilizes while it's on. A fountain that runs UVC for just 1 hour a day leaves the water unprotected for the other 23. Mattte's 3-hours-on, 1-hour-off cycle runs at least 18 hours a day, so bacteria and biofilm never get a long enough stretch to take hold.
With 18 hours of daily UVC and a zero-dead-corner interior, it stays far cleaner than a traditional fountain. A quick weekly rinse plus a deeper clean every 2–4 weeks is plenty — it takes apart in three seconds and just minutes to clean.
About once a month. Every unit ships with a filter already installed, plus a free 6-month filter set (6 pcs, worth S$27) — so your first six months are covered. Swapping one takes seconds — no tools needed.
One filter, four layers: coarse sponge and fine filter cotton catch hair and sediment first, then a disc alternating activated carbon with softening resin from the UK brand Purolite removes residual chlorine, odour, and impurities while softening the water. Standard softening resin is sodium-form (Na⁺) and adds sodium as it softens; ours is a weakly-acidic hydrogen-form (H⁺) resin that releases hydrogen ions instead — no sodium added to the water. The resin is certified to NSF/ANSI-61 for drinking water safety in the US, so it's one less burden on your pet's kidneys.
Yes. The UVC-LED is fully sealed inside the underwater motor module, so your pet never comes into contact with it — it sterilizes the water flowing through the internal channel, not the surface of the bowl.
No. It runs at about 30 decibels — quieter than a whisper — thanks to a sound-dampening double-walled tank and a low-friction ceramic-shaft pump. Many owners keep it right in the bedroom.
The box includes a USB-A to USB-C cable, but no power adapter. Any standard 5V charger works — a typical 5V/1A or 5V/2A phone charger is ideal. Please avoid fast-charging adapters (PD, QC, GaN): this is a low-voltage device (5V/500mA), and fast charging may prevent it from starting. If you need a replacement cable, use USB-A to USB-C — not C-to-C.
Yes — the pump, base tray, and filter are all available separately, so a single worn part doesn't mean replacing the whole fountain.
