About RP-U04
RP-U04 is an under-sink hydrogen-water RO purifier that hides under the kitchen sink and leaves the countertop clear. It runs at 1000 GPD with a pure-water flow of 2.6 L/min, so it keeps up with a busy household kitchen. The system uses a PCC composite pre-filter plus RO filtration, with a rated purified volume of 4000 L. It is aimed at brand owners who want a premium under-sink model with a hydrogen-water story.
Why buyers choose it
- High flow for an under-sink unit: 1000 GPD RO capacity with a pure-water flow of 2.6 L/min.
- Hydrogen water: the catalogue lists a hydrogen concentration of ≥2000 ppb, stated as a manufacturer claim rather than a third-party test result.
- PCC composite pre-filter + RO filtration, with a rated purified volume of 4000 L.
- Compact under-sink footprint: 420 × 170 × 420 mm in an ABS housing.
Best for
- Homes that want hydrogen water without a countertop machine.
- Kitchens where counter space matters and the purifier should stay out of sight.
- Distributors selling a premium under-sink RO line.
