Uno is an under-sink microfilter, designed and built in Italy. It clears what you do not want from your tap water, and lets the rest of your kitchen stay exactly as it is.
Across Major European Cities and World Class Brands

The plant that builds Uno has been making filtration systems for over thirty years. Three hundred installations across Europe — hotels, restaurants, public buildings — drink from the same technology that now fits under a domestic sink. We did not invent the filter. We made it small enough, and quiet enough, to belong at home.
We make one filter. Not a range. Not a system with options. The cartridge fits vertically or horizontally, in any kitchen, with the tap that is already on the counter. Twelve months of clean water, then a single replacement. No app. No subscription you cannot cancel. No reminder that pings on a Sunday morning.
The shape of Uno is the shape of restraint. That is also how it tastes.
The body is anodised aluminium, drawn by the same hands that draw cooking pots and bicycle frames. The certification is European. The packaging is paper. What is inside the cartridge filters at 0.5 micron and removes microplastics, chlorine taste, and sediment without taking the minerals you want to keep.
We will tell you what is in your water if you ask. We will not tell you to be afraid of it.
Uno is built to last decades. The cartridge is the only thing you replace, and only once a year. If something breaks, we send the part. If you move, the filter comes with you. If your sink is unusual, write to us before you buy — we will tell you the truth.
