Our Review
SeawaterPro has built a following among cruisers by offering high-output desalination at prices well below traditional marine brands, using standard, serviceable RO components you can maintain yourself.
It asks a bit more of the owner in setup and upkeep, and it needs AC power, but the value-per-gallon is excellent for boaters and off-grid builders comfortable with some hands-on work.
Pros
- High output for the price
- Standard, serviceable components
- Popular in the cruising community
Cons
- More owner setup and maintenance
- AC power required
The HU Recommendation
Best value for high-output desal if you're comfortable maintaining your own gear. Pair with adequate generator or shore power.
