Description
Ice, hot and cold water — no kitchen renovations, no heavy bottles to carry.
The UMBOX W91 filters tap water using reverse osmosis and dispenses it as you need: cold, room temperature, warm, or hot. And it makes ice. No plumbing connection needed, no plumber required, and no drilling — just fill the tank and plug it in.
Ice on demand, directly into your glass
Place your glass, touch the button, and the cubes fall directly in. The first batch is ready in 8 to 15 minutes, with no bags, no trays, and no waiting for the freezer.
Four temperatures, one touch
Cold for summer, room temperature for everyday use, warm for baby bottles, and hot for tea or coffee. Select on the panel before filling your glass — and there's also volume selection, to always serve the same amount without overflowing.
Water quality in numbers, on screen
The panel simultaneously displays two TDS values: that of the incoming water and that of the filtered water. You don't need to believe in promises — the difference between the two numbers is visible every time you pour a glass.
Four stages of filtration
PCC composite filter for sediments and chlorine, high-flow reverse osmosis membrane, mineralizing cartridge, and activated carbon post-filter. The membrane acts on dissolved fractions — limescale, nitrates, and heavy metals — and the final carbon filter refines the taste.
Minerals returned to the water
After osmosis, the mineralizing cartridge replenishes minerals in the water. This is the answer to the most common objection about reverse osmosis: clean water doesn't have to taste like nothing.
Compressor cooling
Compressor system with R600a refrigerant gas — the same principle as a refrigerator, not a thermoelectric plate. Genuinely cold water, even in August.
Hassle-free maintenance
Components that need washing can be removed without tools. Filter replacement is done from the front of the appliance.
No installation
Place it on the counter, fill the tank, plug it in. No drilling, no connection to the drain, and no asking the landlord for permission — and if you move, you take it with you.
