Change Your Water

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.

What It Removes

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.

5-stage composite filtration — PP Pre-Filter, Carbon Block, Granular Activated Carbon, Scale Inhibitor, Fine Mesh Barrier
1

PP Pre-Filter

Captures sediment, rust and large particles before reaching the carbon layers.

2

Carbon Block

Removes chlorine, heavy metals and odour, the most common tap water complaints.

3

Granular Activated Carbon

Adsorbs pesticides, PFAS and micro-pollutants at 0.01 micron accuracy.

4

Scale Inhibitor

Prevents limescale buildup, essential in hard water areas across Europe.

5

Fine Mesh Screen

The final barrier against any remaining particles before the water reaches you.

Chlorine removal: 99.9% Scale removal: 99% Odourless output
Soft waterUp to 3 months per cartridge
Auto-trackedFilter life % on display, always live
Hard waterApprox. 3–6 months per cartridge

*Each cartridge rated to 1,000 litres. Replacement cartridges at umawater.com.

Two Modes

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.

UV Protection

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.

Questions

Everything you need to know before you buy.

No. A micro-hydraulic turbine inside generates electricity from your water flow. The display and UV light activate automatically when the tap is on. Nothing to charge, nothing to replace beyond the filter cartridge.
Each cartridge is rated to 1,000 litres. Soft water areas: up to 12 months. Hard water areas (London, Madrid, Rome, Amsterdam): 3–6 months. The display tracks this automatically and changes colour when replacement is approaching.
Chlorine, heavy metals (lead, copper traces), rust, sediment, pesticides and PFAS at 0.01 micron accuracy. The UV light also helps reduce bacteria at the outlet. Designed for European municipal tap water only.
Fits standard kitchen taps with thread diameters 19.5–23.5 mm. Six adapters included, covering 99% of European faucets. Not compatible: pull-out spray taps, sensor taps, wall-mounted mixers, or non-standard thread sizes.
Under 5 minutes. Remove aerator. Pick adapter. Screw on. Attach filter body. Run cold water 30 seconds. The display lights up. Full illustrated guide in the box.
No, cold water only through the filter. Switch the dial to Original mode for hot water, washing up or rinsing. Instant, no tools needed. Doing this extends filter life significantly.
Filtered: all 5 stages plus UV. For drinking and cooking. Original: bypasses the filter entirely. For hot water and non-drinking tasks. The mode selector is the dial on the side of the unit body.
When the display signals it: unscrew the filter housing, swap the cartridge, reattach, hold reset button 5 seconds while water runs. Display resets to 100%. Replacements at umawater.com.

What our customers say.

The Name Behind the Water

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.

The Story

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.
