Q&A

What is the difference between UF (ultrafiltration) and reverse osmosis?

Reverse osmosis removes up to 99% of contaminants, including heavy metals and microorganisms, while UF does not filter out nitrates, endocrine disruptors, or pharmaceutical residues.

What residual pressure do I need on my boat?

It is recommended to have at least 2 bars of residual pressure to ensure optimal operation of the OneZero osmosis system.

What is the OneZero Osmosis unit supplied with?

The OneZero is supplied with all the fittings, pipes, O-rings, valves, a gooseneck, as well as the first membranes and pre- and post-filtration filters. You can also upgrade it with a 3-way tap or a tabletop fountain, but these options are additional.

What maintenance is required?

The pre-filtration and post-filtration cartridges should be replaced every 6 to 12 months, while the reverse osmosis membranes have a lifespan of 2 to 4 years, depending on usage and water quality, to maintain optimal performance.

Can I connect my osmosis unit to a fountain or an integrated tap?

Yes, the OneZero pairs perfectly with a 3-way tap, an Oceane fountain (providing fresh and sparkling water on demand), or our integrated U4/U5 taps (which also provide hot water).
