UNO is an under-sink microfilter, designed and built in Italy. It takes out of tap water what you don't want — and leaves your kitchen exactly as it is.

We bring our experience home so that reaching for tap water becomes natural, safe and everyday — as it should be. The filter takes out of the water what you don't want and leaves the rest alone: we don't change your tap, we don't drill into the countertop, we don't ask for space by the sink. Calcium, magnesium and potassium stay, because they are what make water taste like water.
We make one filter. Not a series, not a platform with options. Twelve months of clean water, then one cartridge change. No app, no subscription you can't cancel, no notification on a Sunday morning.
UNO's shape is a shape of restraint. It tastes the same way.
Our team comes from thirty years of experience in water treatment technology. We have completed more than three hundred municipal installations across Europe. UNO is the same know-how, scaled down to fit in a home kitchen.
