HERO Inhaler / HERO Inhaler Pro — How to Use & Configure Hydrogen / Hydrogen-Oxygen (4m12s)

1. Introduction

This manual covers the full Hydrogen Machines range and consolidates the universal guidance that applies to every hydrogen device we sell — safe setup, operation, maintenance, storage, troubleshooting, and warranty. Model-specific figures (output, water, users and power) for every system in the catalogue are in the quick reference in section 5, taken from each product page. Where instructions differ by product type, sections 6–10 have a short subsection for each. For anything not covered here, or for support with a specific unit, please contact us via the contact page.

2. Before your machine arrives

Getting your water sorted before your machine turns up means you can use it the moment it's out of the box — no delay, no last-minute trip to the shops.

What water you need

Most machines in our range require distilled or deionised water at TDS < 5 ppm. HERO Bath has a more tolerant requirement of TDS < 30 — check your model's row in the reference table below for its exact spec. In all cases, ordinary tap, filtered, or mineral water will cause scale buildup on the internal electrode and can damage the unit, voiding your warranty.

If your model has a separate drinking-water tank (in addition to the hydrogen-production tank), that tank is more relaxed — RO, filtered, or cool boiled water is fine, since it isn't used for hydrogen production. Check your model's row in the reference table below to confirm whether it has one tank or two.

How much water you'll actually use

Electrolysis uses very little water — as a rule of thumb, a machine uses about 45 mL of water for every hour of use at 1,000 ml/min flow (roughly a tenth of a glass). At a typical 30-minute daily session, even our highest-flow model uses only around 2 litres a month. A single bottle of distilled water will last most users several weeks, regardless of which model you own.

Model / tier	Flow rate	Water used per hour
HERO Inhaler Go (low) / HERO Dual 20-1000	660 ml/min	~30 mL
HERO Inhaler Go (high) / HERO Dual 20-1500	1,000 ml/min	~45 mL
HERO Inhaler 900	900 ml/min	~40 mL
HERO Inhaler 1200	1,200 ml/min	~54 mL
HERO Inhaler 2000 / HERO Dual 20-2000	1,400–1,800 ml/min	~63–81 mL
HERO Inhaler Pro 3000	3,000 ml/min	~135 mL

Applies to the inhaler/generator models (HERO Inhaler Go, HERO Inhaler & HERO Inhaler Pro range, HERO Dual 20 inhalation). HERO RO Dual 10 is a water-only machine, and HERO Bath circulates and treats bath water directly rather than consuming from a separate reservoir, so it isn't listed here.

Where to buy it

Distilled water is inexpensive and widely available — no need to order anything special or wait for delivery:

Supermarkets — usually sold for ironing, near the laundry aisle
Auto accessory stores — sold as distilled water for 12 V car batteries
Hardware stores
Pharmacies — sold as distilled water
Some servos / petrol stations

A few litres is enough to get started — enough for your first several sessions while you settle into a refill routine.

If your machine arrives in cold weather

If your order arrives during cold weather, or has been in transit through a cold climate, let it sit at room temperature for a few hours before first use. Cold shipping can cause residual moisture in the internal water lines to partially freeze; running the unit before it's acclimated can risk damaging internal components. This is a simple precaution, not a fault — once warmed to room temperature, your machine is ready to use as normal.

Quick start: setting up your HERO Inhaler

Placement. Put the machine on a stable, flat surface near a power socket, with the side vents clear. Keep it away from open flames, gas cooktops and heat sources. If it arrived in cold weather, let it sit at room temperature for a few hours first.
Water. Use distilled or deionised water only (TDS under 5). Tap, filtered or mineral water will cause scale and can void the warranty. Open the water tank cover on top, fill until the “full water” indicator shows on the display, then close the lid tightly. A tight lid stops hydrogen leaking out.
Connect the cannula. Push the nasal cannula tube firmly onto the hydrogen gas outlet on the top panel.
Power on. Plug in the power cord and switch on the power switch at the back. Then press the ON/OFF button on the front panel.
Set the time and start. Press the timer button to set your session length, then start. The display shows the hydrogen flow and the time remaining. Sit comfortably and breathe normally through the cannula.
Finishing. The machine stops when the timer reaches zero. Press ON/OFF to switch it to standby. If you switch it off at the back, wait at least 5 seconds before switching it on again.

Looking after your machine

TDS light red: switch off, unplug, drain the water using the drain plug at the back, put the plug back in and refill with fresh distilled water.
Descaling: please contact us before descaling your machine and we’ll give you the correct method for your model.
Moving or long breaks: keep some water in the tank so the cell stays hydrated, and unplug the machine. Only drain it for transport.
Milky water during use is normal and clears quickly.

Control panels vary slightly between models. If anything doesn’t match your machine, message us on WhatsApp or use the contact page and we’ll walk you through it.

3. Important information before use

Read every point in this section before switching the unit on for the first time.

Use the correct water only. All machines require soft water (distilled or deionised, resistivity greater than 2 MΩ·cm, TDS < 5 unless the per-model table below specifies otherwise). Tap water will scale the PEM stack, reduce hydrogen output, and shorten the life of the electrolysis cell — this is the single most common cause of warranty issues. Full guidance: what water should you use? →
Match the voltage. Use only the power cord and voltage specified for your model. Do not use adaptors, converters or extension leads that alter the supplied voltage.
No open flame, no smoking near the unit. The output stream is hydrogen. Keep the device away from open flame, cigarettes, gas hobs, and any direct heat source.
Never block or obstruct the air outlets. Place the unit on a stable, flat surface with adequate clearance on every side. Blocked vents can damage the machine.
Do not let the unit leak. If you notice water pooling around the base, switch off at the panel, unplug from the wall, and contact support before further use.
Drain and replace water when the TDS indicator shows red. This means the water no longer meets purity requirements and must be swapped promptly — see section 5.
Never let the tank run dry for extended periods. Running the stack with insufficient water can damage internal components.
Standby vs full shutdown. Switching off at the front panel places the unit in standby. For extended periods of non-use, cleaning, transport, or before draining the tank, always fully unplug from the wall socket.
Do not open, modify, or repair the unit yourself. There are no user-serviceable parts inside. Any unauthorised opening voids the warranty.
Stop use immediately if you notice any unusual odour, sound, or overheating. Switch off, unplug, and contact support.

4. Operating principle

Your hydrogen device uses electrolysis to split water molecules into hydrogen and oxygen gas. Pure or distilled water is passed through an internal electrolysis cell, producing a hydrogen-rich gas stream (or hydrogen-rich water, on dual-mode models) at a controlled flow rate. Purity levels in model-specific documentation are standard across the range. Because this process relies on precise water chemistry, using anything other than the recommended water type can affect performance and, over time, damage the internal cell — this is why water quality requirements are strict and model-specific.

HERO Bath circulation system

The HERO Bath system is the exception to the single-tank inhaler pattern above. It uses a closed-loop design: bath water is drawn into the machine through one hose while a separate internal distilled-water tank feeds the electrolysis cell, and the resulting hydrogen is infused into the circulating bath water before it returns through a second hose. The inhaler models do not circulate bath water — they generate gas from a single internal tank and deliver it directly through the cannula or mask.

Diagram showing how the HERO Bath draws bath water through a hose, generates hydrogen from a separate distilled water tank, infuses it into the circulating water, and returns it to the bath through a second hose — HERO Bath uses a closed-loop system — bath water circulates through the machine, where it's infused with hydrogen generated from a separate distilled water tank, then returns to the bath.

6. Operating instructions

Inhalation machines (HERO Inhaler Go, HERO Inhaler, HERO Inhaler Pro and HERO Dual 20)

These on-screen alerts are common across the inhalation range. The touchscreen panel pictured is representative of the touchscreen display; other models use a different physical panel but follow the same underlying logic.

Console alarm: TDS value is too high, please change the water and restart — What it means: The water in the tank isn't pure enough — it may contain minerals, salt, or other impurities.
What to do: Drain the tank fully, then refill with fresh purified or distilled water. It's best to rinse and refill 2–3 times until the water runs clean before restarting the unit.

Console alarm: please add time — What it means: The session timer is set to zero, so there's no run time scheduled.
What to do: Increase the timer setting before pressing start.

Console alarm: temperature is too high — What it means: The internal temperature has reached its upper limit (around 60°C).
What to do: Switch off and let the unit cool down for a while before continuing. Refreshing the water in the tank can also help.

Console alarm: please check the TDS sensor — What it means: The unit can't get a reading from the water-quality (TDS) sensor — usually due to a blockage, occasionally a sensor fault.
What to do: Drain and refill the tank once or twice, then restart. If the message continues to appear, the sensor itself may need attention — contact support.

Console alarm: please add water — What it means: The tank has dropped below the safe minimum.
What to do: Refill with purified or distilled water.

Console alarm: water level too high — What it means: The tank has been overfilled past the maximum line.
What to do: Drain a small amount from the rear drain outlet until the level is back in range.

On the HERO Dual 20, switch between Hydrogen Enjoyment (inhalation) and Hydrogen Water (drinking water dispensed straight into a glass) on the touch panel.

Setup and care guidance for this model is available from our team — message us on WhatsApp or use the enquiry form.

HERO Bath 6 L/min Hydrogen Nano-bubble System

Fill the tank with purified water (TDS under 30 ppm).
Place the inlet hose with its filter head and the outlet hose with its aeration head in the bath.
Set the timer on the touchscreen — 15 to 60 minutes in 15-minute steps (default 15 minutes).
Hydrogen-rich water returns through the aeration head.

Use in a ventilated room, never in a closed room, and plug into an earthed (grounded) outlet. No plumbing installation is required. Filling and draining can be automatic via the supplied 1 m silicone hose.

HERO Bottle

A small amount of water is in the bottle when it arrives. The membrane must stay moist to function correctly; this is normal and not a sign of prior use.
Before the first cycle, fill the bottle and let it soak for 15–20 minutes to rehydrate the membrane.
Water temperature range: 0–60°C.
Dissolved hydrogen dissipates over time — drink soon after a cycle completes.

HERO Irrigation Hydrogen Nano-bubble System

The full HERO Irrigation instruction manual is being revised and is available on request through the contact page.

Operating environment: 0–40°C, humidity below 85%, no direct sunlight, no open flames, good ventilation. Never use in a closed room.
Place the machine horizontally with the front panel facing the operator. The power supply must be properly grounded.
First use: add water to the tank, then wait 5 minutes before turning the machine on.
Turn on the power switch on the rear panel to enter standby, then tap start/pause on the display. The default run time is 15 minutes; use “+” and “−” to adjust in 15-minute steps up to 60 minutes.
Connects to the facility’s existing circulation line. Inlet water pressure: 0.1–0.4 MPa. Outlet connection: G1/2 thread, 8 mm push-fit with valve.
Hydrogen nano-bubbles are visible immediately at startup. Typical continuous operation is 1–4 hours. Dissolved hydrogen dissipates to near-zero within roughly 2 hours of stopping, so time treatment to irrigation cycles.

7. Inhalation configurations

These inhalation configurations apply to the inhalation machines and to the HERO Dual 20 in inhalation mode, depending on how many people are using the unit and which gas mode is selected. HERO Bottle, HERO Purity 200-110, HERO RO Dual 10, HERO Bath and HERO Irrigation have no inhalation mode.

8. Maintenance

Inhalation machines

Drain and replace the water in the tank whenever the TDS (water quality) indicator shows red — this means the water no longer meets the required purity and should be swapped out promptly.
Before draining, always switch off the unit at the panel and unplug it from the power socket first.
It's normal for water to appear milky or cloudy during hydrogen production — this clears on its own after a short period and is a sign the unit is working correctly.
If the machine will be unused for an extended period, keep water in the tank rather than draining it completely. The internal hydrogen-generating cell needs to stay hydrated to perform well and last — letting it dry out for weeks or months can reduce performance and shorten its lifespan. If you do need to empty the tank (for example, before shipping or moving the unit), aim to refill and use it again reasonably soon after.
Never let an external drinking water source (where applicable) run dry for long periods, as this can damage the unit.
Keep all air outlets clear and unobstructed at all times.

Periodic descaling

Even with correctly purified or distilled water, trace mineral scaling can gradually build up on the internal PEM cell over extended use. Left unaddressed, this can reduce hydrogen output and shorten the life of the electrolysis stack.

Please contact us before descaling your machine and we’ll give you the correct method for your model.

If water spills onto electronic components

If any water splashes or spills onto the display, buttons, or other electronic parts of the unit, unplug the machine first, then dry the affected area with a hair dryer on a cool or low-heat setting, holding it at a short distance to avoid overheating any components. Make sure everything is completely dry before switching the machine back on.

HERO Bath 6 L/min Hydrogen Nano-bubble System

Rinse the filter and aeration heads in clean water and scrub gently with a soft brush; no steel wool, no strong acid or alkaline cleaners, no hot water; dry after cleaning. Unplug before cleaning or servicing. Drain the machine manually or automatically if the TDS alarm shows.
