System overview

What Is a Home Hydrogen Water System?

A home hydrogen water system is a residential water treatment solution designed to infuse purified drinking water with molecular hydrogen gas (H₂) using electrolysis — producing hydrogen-rich water at the point of use, on demand.

1

Water Purification Filter

Removes chlorine, sediment, and impurities before hydrogen infusion begins

2

Hydrogen Generator Module

SPE/PEM electrolysis cell — splits water molecules to release dissolved H₂ gas

3

Hydrogen Infusion Chamber

Dissolves and stabilizes H₂ concentration before water reaches the faucet

Unlike bottled hydrogen water or portable generators, a home system produces fresh hydrogen-rich water continuously — which matters because H₂ gas dissipates when exposed to air over time.

How Does a Home Hydrogen Water System Produce H₂?

The core process is electrolysis — a method using a small electrical current to split water molecules into their components. Three stages work in sequence:

Step 1

Filtration

Tap water passes through a pre-filter — removing chlorine, sediment, and impurities before entering the electrolysis cell

Step 2

Electrolysis

A small current at the SPE/PEM membrane splits H₂O into hydrogen (H₂) and oxygen (O₂) — oxygen is vented out

Step 3

Infusion

H₂ gas dissolves back into the purified water at up to 1,500 ppb — dispensed fresh through the smart faucet

Why fresh generation matters: Hydrogen gas gradually escapes from water when exposed to air. Generating H₂ at the point of use — directly from your faucet — delivers consistently higher concentrations than bottled hydrogen water that may have been stored for days or weeks.

Product overview

What Is the ALPHA Hydrogen Water Module?

A compact under-sink hydrogen water generator — permanently installed, connecting directly to your existing plumbing, producing hydrogen-rich water on demand from a dedicated smart faucet.

1,500

ppb H₂ max concentration

−600

mV ORP antioxidant potential

7.0

pH neutral, balanced water

The module connects under the sink to most water supply systems. It transforms filtered water into hydrogen-rich drinking water through advanced SPE/PEM electrolysis technology.

ORP (Oxidation-Reduction Potential) — measured in millivolts (mV), it indicates water's capacity to act as a reducing agent. A reading of −600 mV is significantly antioxidant compared to standard tap water at +100 to +400 mV.

Unlike alkaline water ionizers, the hydrogen module produces neutral-pH water (7.0) — making it suitable for all household uses, including preparing infant formula and taking medication.

ALPHA Hydrogen Water Module

Why Choose the ALPHA Hydrogen Water Module?

Six reasons the ALPHA module stands out compared to portable hydrogen devices and bottled hydrogen water options.

High H₂ Concentration

Up to 1,500 ppb

Achieves research-relevant H₂ levels consistently at point of dispensing — not diminished by storage or transport delay.

Strong ORP Performance

Up to −600 mV

Negative ORP indicates reducing (antioxidant) capacity. A 700–1,000 mV difference from standard tap water is a significant measurable change.

Neutral pH Water

pH 7.0

Safe for all household uses — suitable for infant formula, medication, and cooking without pH-related concerns.

Universal Compatibility

RO · UF · Mineral · Tap

Works with reverse osmosis, UF filters, mineral filters, or direct tap supply. No new plumbing required in most kitchens.

Compact Under-Sink Design

Space-saving

Installed out of sight under the sink. Nothing on the counter. A dedicated smart faucet above provides instant access.

Premium Smart Faucet Included

How Is the ALPHA Module Installed?

Three connection configurations — choose the one that matches your current kitchen setup. Most installations complete in 30–60 minutes.

30–60 min · DIY-friendly

Direct connection to the water supply line

The simplest configuration. The module connects directly to the cold water supply line — no additional filter purchase needed. The module's built-in filter handles pre-treatment before hydrogen infusion begins.

  • Cold water supply line → hydrogen module inlet
  • Module outlet → smart faucet via dedicated tubing
  • No extra filter required
  • Suitable for municipal tap water with low sediment

30–60 min · DIY-friendly

Connection to a UF or mineral pre-filter system

If you already have a UF (ultrafiltration) or mineral filter installed, the module connects downstream — receiving pre-filtered water for hydrogen infusion. This preserves natural mineral content while adding dissolved H₂.

  • Cold water supply → existing UF / mineral filter
  • Filter output → hydrogen module inlet
  • Module outlet → smart faucet
  • Mineral ions (Ca²⁺, Mg²⁺) retained in output water

45–60 min · Plumber optional

Connection to an RO (reverse osmosis) system

The module connects after an existing RO system, using highly purified RO output as feedwater. This produces ultra-pure hydrogen-rich water. A remineralization filter between RO and module is optional but recommended for taste.

  • Cold water supply → RO system (existing)
  • RO output → optional remineralization filter
  • → hydrogen module → smart faucet
  • Best for households with serious contamination concerns

FAQ

Frequently Asked Questions About Hydrogen Water Systems

Hydrogen-rich water contains dissolved molecular hydrogen gas (H₂) — the smallest molecule in existence — at concentrations measured in parts per billion (ppb). H₂ is studied for its selective antioxidant properties: it can neutralize harmful hydroxyl radicals without interfering with beneficial cellular signaling. Because of its small size, H₂ can cross cell membranes and the blood-brain barrier — access that larger antioxidant molecules cannot achieve.
The system filters incoming tap water, then passes it through an SPE/PEM electrolysis cell. A small electrical current splits H₂O molecules into hydrogen (H₂) and oxygen (O₂). Oxygen is vented out while H₂ dissolves back into the purified water — dispensed fresh through the dedicated smart faucet at up to 1,500 ppb.
Current research indicates hydrogen water is generally considered safe for regular consumption. H₂ is a naturally occurring gas already present in trace amounts in the gut. Published human studies — including long-term trials — have not reported adverse effects in otherwise healthy adults. If you have a specific health condition or take medication, consult your physician before making dietary changes.
Many published studies use concentrations between 800 ppb and 1,600 ppb. The ALPHA module produces up to 1,500 ppb — within this research-relevant range. Concentration is best measured at the point of consumption, as H₂ gas dissipates over time in open containers.
Yes. H₂ is a gas and gradually escapes from water when exposed to air — particularly in open containers. This is why fresh generation at home is more effective than bottled hydrogen water stored for days or weeks. Drink water soon after dispensing to maximize H₂ concentration. Tight-capped bottles slow dissipation significantly.
Yes. The ALPHA module supports three configurations: direct tap supply, downstream of a UF or mineral filter, or downstream of a reverse osmosis (RO) system. Most installations complete in 30–60 minutes without requiring a plumber.
Alkaline water has elevated pH (typically 8.5–10.5), produced by concentrating mineral ions through electrolysis. Hydrogen water contains dissolved H₂ gas at neutral pH (~7.0). The ALPHA module produces neutral-pH hydrogen water — not alkaline water. For households wanting both alkaline and hydrogen water, a full water ionizer (Alpha 1700 or U1700) is the more complete solution.
High-quality SPE/PEM modules are designed for years of continuous operation. The pre-filter stage requires periodic replacement — typically every 6 months for an average household — to maintain optimal H₂ output. The electrolysis module itself is a long-life component that does not require routine replacement under normal use conditions.
