Our Review
Rainman is one of the most respected names in marine desalination, valued for watermakers that are genuinely portable and offered in AC, DC, and petrol versions to suit any vessel or off-grid site.
Output scales from modest to substantial depending on model, and the modular design lets you stow the unit when not in use. For boats and coastal homes it's a dependable freshwater source.
Pros
