FAQ
Ultrafiltration removes suspended particles and some bacteria, but it does not eliminate dissolved contaminants such as nitrates, viruses, endocrine disruptors, or pharmaceutical residues. Reverse osmosis goes further by filtering at a molecular level, removing up to 99.9% of contaminants, including the smallest and most persistent impurities.
Our mains-connected dispensers provide chilled, ambient, hot, and sparkling water. They are designed for offices, hospitality, and professional environments, supporting daily hydration, beverage preparation, and sustainable water service with no plastic bottles.
Absolutely. The OneZero reverse osmosis system integrates perfectly with our U4 and U5 taps as well as the Oceane water dispenser. This allows you to enjoy chilled, hot, or sparkling purified water from a single elegant point of use, combining performance, convenience, and design.
Yes. We design dedicated marine reverse osmosis systems specifically for yachts and boats. Our systems can treat dock water or desalinate seawater, providing safe drinking water even after long periods of tank storage.

Our water treatment systems are designed for a wide range of environments, including offices, hotels and restaurants, yachts, as well as private homes, schools, and industrial sites. Each sector has specific requirements—whether it’s water quality, hygiene standards, or technical performance—so we provide tailored solutions adapted to every use.
Purchasing is the best option for long-term autonomy and full ownership of your system. Rental is ideal for organizations that prefer a fully managed service, including installation, maintenance, filters, and technical interventions. It provides a predictable monthly cost with no unexpected expenses, making it a simple and hassle-free solution.
All our installations are built using ACS-certified components and comply with strict international standards, including ISO 9001 for quality management and ISO 14001 for environmental performance. In sensitive environments such as healthcare or food service, we also apply dedicated anti-legionella disinfection protocols to ensure maximum safety and reliability.
