I've been using this system for a year and a half, and it's been a game-changer for boat living on the Thames and the London canal network. I used to be the grumpy host annoyed by guests brushing their teeth or offering to do the dishes, but not anymore!!! What I Love Durability: Incredibly durable and works like a charm even in rough conditions. Ease of Setup: Easy to set up, and I was filtering water within minutes. Power and Speed: My tank fills quickly without draining my inverter, except when filters get clogged, which is a good reminder to change them. Filtration Quality: Consistently effective; I keep testing samples, and it’s still doing its job. Cost: Annual maintenance cost is reasonable. Just stay on top of filter changes. Filters are cheap. Support: Damian has been absolutely wonderful in troubleshooting and offering help when something needs figuring out. Things to Consider Variable Water Quality: The water quality will vary based on the source and maintenance. Some areas in town can clog filters quickly, leading to more frequent changes. Metrics: Keep a log of filter changes and runtime. A flow meter is a good investment. Conclusion The Offgrid StageOne is robust, efficient, and ideal for off-grid living. It's easy to use, reliable, and a restorer of dignity at a tremendous value.
