Almost every under-sink RO system on the market is imported, and this one genuinely is not, which is the whole argument for paying roughly double the price of a comparable spec from an overseas brand. The five-year warranty is unusually long for residential RO, where three years is generous, and the storage tank carries the same term. Resins are described as FDA and NSF compliant, which is a materials statement rather than a performance certification: this system carries no NSF/ANSI 58 certification for RO performance, and 58 is the standard that would substantiate contaminant reduction claims. Flow behaves like any tank-based RO, producing gradually into storage rather than on demand, and the manufacturer declines to publish a single GPM figure because it depends on pressure and temperature. Faucet finish is cosmetic and does not change performance.
- Genuinely built and assembled in the USA with 98%+ American parts
- Five-year warranty including the storage tank
- Five and six stage options, the six adding alkaline remineralisation
- Colour-coded tubing and four connections make installation approachable
- Four faucet finishes
- Filter cartridges are also American made
- No NSF/ANSI 58 certification for reverse osmosis performance
- Roughly double the price of imported equivalents
- No published flow rate figure
- Tank-based, so it produces gradually rather than on demand
- RO wastes water to drain
- Membrane replacement every 2-5 years is an additional running cost
