Dometic Spot Zero Water Purifier Systems

Imagine a gleaming boat and a spot-free wash down with no need to go back and wipe or chamoisdry the vessel’s finished surfaces.

The Dometic Spot Zero removes 95-99% of total dissolved solids (TDS) from any dock or on-board water supply. The result is soft, pure water that lets water-sprayed surfaces dry clean without leaving spots that have to be wiped away. Air-drying after a Spot Zero rinse helps preserve the boat’s paint and wax finishes since "wiping away" dissolved solids can grind them into finished surfaces, creating minute scratches.

Fill your holding tanks with Dometic Spot Zero water to be used for bathing, cooking, drinking, and making crystal-clear ice on-board. Enjoy spot-free glassware, dishes, and shower surfaces, and eliminate mineral build-up in ice machines for less maintenance.

Dometic Spot Zero uses a multi-step reverse-osmosis process: Filters remove sediment, granulated activated carbon removes chlorine, chloramines and heavy metals, and a semipermeable membrane allows the passage of water but not ions or larger molecules. In addition to eliminating 95-99% of TDS, Dometic Spot Zero also removes viruses, cysts, bacteria, and radioactive contaminants from any dock water anywhere in the world.
