RO-QUAD H₂
Four-stage alkaline reverse osmosis for purified, remineralized, alkaline, and hydrogen-rich drinking water.
ADVANCED DRINKING-WATER TREATMENT
RO-QUAD H₂ combines reverse osmosis purification with remineralization, alkaline conditioning, and hydrogen-producing ionization in one compact under-counter system.
THE FOUR-STAGE PROCESS
Stage 1 — Pre-filtration helps reduce sediment and protects the downstream components.
Stage 2 — The reverse osmosis membrane provides advanced purification and can reduce total dissolved solids by up to approximately 97% under suitable conditions.
Stage 3 — Remineralization and alkaline conditioning restore beneficial minerals and can raise pH to approximately 9.5 or higher, depending on source-water conditions.
Stage 4 — The bio-ceramic ionizer produces hydrogen-rich water and can create negative ORP readings as low as approximately −250 mV under suitable conditions—without requiring electricity for ionization.
DESIGNED FOR DAILY USE
The compact system installs beneath the kitchen sink and supplies treated drinking water through a dedicated faucet. Production capacity is up to 50 gallons per day, with a 4-gallon theoretical storage tank.
OPERATING REQUIREMENTS
Designed for incoming water pressure from 40 to 125 PSI and temperatures from 40°F to 100°F. Actual performance varies with feed-water quality, pressure, temperature, installation, filter condition, and usage.
FILTER SERVICE
Replacement intervals generally range from 6 to 24 months or up to 2,000 gallons, depending on the component, local water quality, and household usage.
WARRANTY OVERVIEW
Five-year limited parts warranty on the appliance, two-year warranty on the storage tank, and one-year labor warranty. Replaceable filters and normal maintenance items are excluded. Full warranty terms apply.
PROFESSIONAL INSTALLATION
Undo Hydro evaluates the available space, plumbing configuration, water pressure, and treatment goals before installation.
