ECHO Refresh
Hydrogen you breathe.
ECHO Refresh is an at-home hydrogen inhalation machine. It splits distilled water by SPE/PEM electrolysis and delivers up to 1,200 ml/min of 99.999% pure hydrogen, plus up to 600 ml/min of oxygen, through a cannula.
Sessions run from 30 minutes to six hours, quietly, while you read, work or rest.

Inhalation vs. drinking
Drinking takes minutes. Breathing takes seconds.
A glass of hydrogen water has to be digested. Inhaled hydrogen passes from the lungs into circulation, and keeps coming for as long as the session runs.
-
Through the lungs
Hydrogen is the smallest molecule there is, and it crosses from the lungs into the bloodstream quickly.
-
A session you can extend
From 30 minutes to six hours: a short reset in the morning or a long one overnight.
-
Pairs with your routine
On its own, or while you read, work, meditate or rest between sauna and cold.
-
Nothing but gas and water
Electrolysis of distilled water, with no chlorine, fluoride, lead, heavy metals or bacteria in the gas you breathe.
The session
Four steps, then just breathe.
01
Fill the tank
Distilled water in the reservoir. The screen tells you when the level is off or it needs changing.
02
Connect a cannula
Two hydrogen ports plus an oxygen channel, for one person or two.
03
Set the time
Anywhere from 30 to 360 minutes on the 7-inch touchscreen.
04
Carry on
It's quiet. Read, work, train or sleep while the session runs.
Three channel ports
Two hydrogen outputs plus oxygen.
Run a session together, or keep a second cannula ready so the machine never sits idle.
- 01
Hydrogen output
Up to 1,200 ml/min of 99.999% pure hydrogen across both hydrogen ports.
- 02
Second hydrogen output
A full second line, so two people can run a session side by side.
- 03
Oxygen output
Up to 600 ml/min of oxygen for protocols that pair the two.
The machine
Built for high output and long sessions.
SPE and PEM technology with a larger-than-average membrane surface area means more hydrogen per watt, and every unit goes through a QA checklist before it ships.
High-flow generator
Up to 1,200 ml/min of hydrogen; Echo rates this at 3–4× most inhalation machines.
7-inch touchscreen
Session timing, settings and real-time alerts.
Ultra-pure output
99.999% pure, with no chlorine, fluoride, lead, heavy metals or bacteria.
Easy to move
Compact, 30 lb, with handles on both sides.
The science
A molecule with a research library.
Molecular hydrogen has been examined in 2,210 peer-reviewed studies. These topics cover inhaling it. Much of the research is early.
2,210
peer-reviewed studies have examined molecular hydrogen.
Oxidative stress
Inhaled molecular hydrogen as a selective antioxidant for cytotoxic oxygen radicals.
Recovery
Hydrogen inhalation and markers of exercise-induced oxidative stress and inflammation.
Cognition
Hydrogen inhalation and measures of fatigue, mood and cognitive performance.
Cardiopulmonary
Hydrogen-oxygen mixed gas inhalation and respiratory symptom outcomes.
Certifications
Tested. Certified. Documented.
Hydrogen output independently certified by H2 Analytics to IHSA standards.

Questions? Answers.
How is inhaling hydrogen different from drinking it?
Drinking delivers hydrogen through digestion, limited to what a glass holds. Inhalation delivers it through the lungs and can continue for hours, so the total exposure can be much larger. Many people do both.
How long should a session be?
Sessions run 30 to 360 minutes. Most people start with 30–60 minutes a day and build from there. Check with your healthcare professional about what suits you.
Can two people use it at once?
Yes. Two hydrogen outputs and one oxygen output let two people inhale at the same time.
What water does it use?
Distilled water in the internal reservoir. The touchscreen alerts you when the level is off or the water is due for a change.
Is it loud?
No. It's designed to stay quiet, so a long session doesn't take over the room.
What does the warranty cover?
Ten years, included, with no registration required.
Talk to your healthcare professional before starting hydrogen inhalation, especially if you have a respiratory or heart condition.
