⚠️ Important Safety Information

To ensure safe operation and prevent injury or product damage:

Use only distilled water (never tap or filtered water). Distilled water is required because it has the lowest amount of TDS (total dissolved solids)
Water requirements: Resistivity >2 MΩ·cm | Conductivity <0.5 µS/cm.
Do not add anything to the water (no minerals, electrolytes, etc.).
Never disassemble the electrolysis cell.
Always drain water before transporting the device.
Do not use near open flame or in poorly ventilated areas.
Avoid confined, dusty spaces and corrosive gases.
Ensure power is grounded and the power port is clean and dry.
Be cautious around static electricity, sparks, or oxygen-rich environments. Elevated oxygen levels combined with hydrogen increase combustion risk.
If you have lung or cardiovascular conditions, or use other respiratory devices, consult a medical professional before using hydrogen inhalation therapy. Controlled clinical data is still limited.

Frequently Asked Questions

The Fill Line Is Difficult to See

On the new Echo Refresh model, the fill line may be harder to see through the viewing window.

The correct fill level is approximately:

11 cups of distilled water (~2.6 liters).

Helpful tip:

When the machine powers on:

A red LED light inside the unit illuminates.
Pressing Play activates a blue LED light, which makes it easier to see the water level while filling.

If too much water is added, the machine will display an error message, and you will need to drain some water before operating.

Is Hydrogen Inhalation Safe?

Published human safety studies suggest that low-concentration hydrogen gas (~2% mixed with air) appears to be safe and well tolerated.

Participants in these studies showed no clinically significant changes in:

Vital signs
Lung function
Neurological function
Standard laboratory markers

However, there are important safety considerations:

Pure hydrogen gas is flammable.
High concentrations of hydrogen mixed with oxygen or air can create fire or explosion risks.

Some poorly designed devices that generate undiluted or high-concentration hydrogen have been associated with equipment failure or safety risks.

For this reason, it is important to only use certified hydrogen inhalation systems designed to safely dilute hydrogen below explosive thresholds, such as the Echo Refresh.

Can I Buy Replacement Cannulas?

Echo Water does not currently sell replacement cannulas directly.

However, you can purchase standard nasal cannulas with a water trap from most:

Online retailers
Medical supply stores
Local pharmacies

One compatible option is available here:

https://www.amazon.com/dp/B07KF28LHQ

Can More Than One Person Use the Refresh at the Same Time?

The Echo Refresh is designed for optimal performance with one user at a time.

This ensures the proper hydrogen concentration and flow rate.

While it is technically possible to split the line using a Y-splitter, doing so would:

Divide the hydrogen output
Reduce the concentration each person receives

For best results, single-user sessions are recommended.

Why Are Different Flow Levels Used?

Different hydrogen flow levels can affect comfort and session duration, but higher flow does not necessarily mean better results.

Low Flow (~900 mL/min)

Best for sleep or long sessions

Gentle and comfortable breathing
Reduces throat dryness
Ideal for overnight use

Medium Flow (~1200 mL/min)

Best for standard daily sessions

Balanced comfort and delivery
Ideal for 20–60 minute sessions
Most common setting for home users

High Flow (~1800 mL/min)

Best for shorter, high-demand sessions

Faster hydrogen saturation
Useful for multi-user or clinical environments

Key Takeaway

Higher flow rates mainly affect how quickly hydrogen fills the breathing circuit, not necessarily how much your body absorbs.

For most at-home users, 1200 mL/min provides excellent results with the most comfortable experience.
