A compact design device

O25 instals the purifier in your home, close to your sink. The unit takes up little space (45 x 40 x 15 cm) and is housed in a sober, clean design that blends into any interior. It is connected to water and electricity. We also offer a new gooseneck tap included in the installation. You can also choose an optional 3-way water tap.

State-of-the-art technology

The reverse osmosis purifier pushes your tap water under pressure through a microscopically small membrane (0.5 manometers). Almost all dry residues will be disposed of down the drain. This eco-friendly technology is the best on the market. Even the International Space Station uses it.
