Stop buying bottles. Start trusting your tap.
The average European household spends over €300 a year on bottled water. UMA WATER costs less than €0.01 per litre to filter. Better taste. Zero plastic. And a display that tells you exactly how much filter life you have left.
"No more single-use plastic."
5-stage filtration. Every drop. Every layer.
UMA WATER's composite filter cartridge works in five stages, each targeting a different type of impurity in European tap water.
PP Pre-Filter
Captures sediment, rust and large particles before reaching the carbon layers.
Carbon Block
Removes chlorine, heavy metals and odour, the most common tap water complaints.
Granular Activated Carbon
Adsorbs pesticides, PFAS and micro-pollutants at 0.01 micron accuracy.
Scale Inhibitor
Prevents limescale buildup, essential in hard water areas across Europe.
Fine Mesh Screen
The final barrier against any remaining particles before the water reaches you.
*Each cartridge rated to 1,000 litres. Replacement cartridges at umawater.com.
Filtered or Original. You choose.
Filtered mode: all 5 stages plus UV. For drinking, cooking and filling bottles.
Original mode: bypasses the filter entirely. For hot water, washing up and rinsing. Using Original for non-drinking tasks extends cartridge life significantly.
Built-in UV. Automatic. Battery-free.
The UV light activates automatically when you switch to Filtered mode. Positioned at the final water outlet, after the 5-stage cartridge, for bacterial protection at the point of drinking. No switch. No battery. It runs on the same hydraulic turbine. Turn the tap on: the UV light is on.
Everything you need. Nothing you don't.

What our customers say.
Some words carry centuries. UMA means water.
In the ancient Aymara language of the Andes, and echoed in the mountains of the Himalayas, UMA has carried one meaning for over a thousand years.
Two mountain ranges. One word. One meaning.
In the Aymara language of the Andean peoples, spoken across Bolivia, Peru and northern Chile for over a thousand years, UMA means water. Across the world, in Sanskrit, Uma is the goddess of light, born of the Himalayas. A word that connects two of the world's greatest mountain ranges. A name that has always meant something elemental. Now it flows through your tap.
