The OneZero, discreet and efficient, is a revolutionary compact reverse osmosis unit that purifies water without electricity. Thanks to its reverse osmosis technology, it guarantees you exceptionally pure water.

 

Compact & Flexible Installation

OneZero’s slim 14.2” x 14.2” x 5.9” design fits into tight marine spaces and can be mounted vertically or horizontally.

No bulky tanks or pumps required —just seamless integration under all but the stingiest of sink cabinetry.

 

Power-Free & Low-Pressure Operation

Forget about running extra wiring or dealing with noisy motors—OneZero requires no electricity, which means zero noise and effortless setup.

Plus, it operates down to just 22 PSI, making it perfect for your boat’s domestic water pressure.

Low Maintenance & Superior Filtration

Dual RO membranes and integrated pre/post-filters remove up to 99.9% of bacteria, viruses, chemicals, microplastics, and PFAs.

Simply replace filters once a year, swap membranes every three years, and track it all with an LED indicator—giving you the safe, fresh-tasting drinking water without the hassle.
