Echo Refresh Review
Clinic-level gas throughput in a home chassis, with 1,800 mL/min output and a ten-year warranty.
The short answer
The Echo Refresh ($7,499.99) is the highest-throughput consumer molecular hydrogen inhalation machine on the market. Delivering up to 1,800 mL/min of 99.999% pure H2 gas backed by a 10-year warranty, it produces fifteen times more gas volume than entry-level 120 mL/min inhalers. However, it produces gas only—it does not make hydrogen drinking water.

Clinic-grade hardware for the home. It delivers more hydrogen gas per minute than anything else here by a wide margin, backed by a ten-year warranty, and it is priced to match.
What we liked
- Fifteen times the gas output of the budget machines, so a useful session takes minutes rather than an hour
- Ten-year warranty, and sessions can run anywhere from half an hour to six
- One of the few inhalers at any price to publish a purity figure - 99.999% - which is the specification that decides an inhaler
What we didn't
- At $7,499.99 list it costs more than the Lourdes Hydrofix, Echo H2 and Echo Flask put together
- It produces gas only and makes no hydrogen water, so covering both means buying a second machine

What this assessment is based on
- A published spec sheet with no output figure on it
- No hands-on use — we have not handled this one
We do not run laboratory measurements of dissolved hydrogen, and we say so on every page. Where a figure comes from a brand rather than an independent laboratory, the label above says which.
Independent certification
We looked for independent test reports on the Echo Refresh and found none published. That is the norm in this category rather than a mark against this machine specifically, but it means every figure above is the brand's own.
No independent certification found
Who the Echo Refresh is for
Buy the Echo Refresh if you require clinical-grade hydrogen gas flow rates (1,800 mL/min) for intensive daily sessions and want the security of a 10-year warranty. Its high throughput achieves therapeutic blood saturation in 15 to 30-minute sessions rather than multi-hour commitments.
Who should skip it
Skip it if you want hydrogen drinking water, have a budget under $3,000, or want a combination unit. The Lourdes Hydrofix ($2,599.90) produces both 1.6 ppm hydrogen drinking water and 120 mL/min inhalation gas for a third of the cost.
Inhalation Flow Rate vs. Drinking Water
Hydrogen inhalation is measured in gas volume (mL/min), delivering molecular hydrogen directly across the alveolar membrane into your bloodstream. While drinking hydrogen water provides gastrointestinal and liver delivery, high-flow inhalation delivers vastly higher total molecular mass per 20-minute session.
Price and where to buy
The Echo Refresh lists at $7,499.99 direct from Echo Water. Echo's list price is $7,499.99. Echo discounts this line often and by a lot, and our code applies automatically at checkout, so the figure you pay is usually well below list - check the cart. Echo sells this line faster than it restocks it, so check the ship date too. List verified on echowater.com 5 Sep 2026. We check this figure monthly and date every change.
Echo Refresh questions
How much does the Echo Refresh cost?
Echo lists the Refresh at $7,499.99, though promotional discounts frequently reduce this at checkout through verified affiliate links.
What is the gas output flow rate of the Echo Refresh?
It produces up to 1,800 mL/min of pure hydrogen gas (H2) plus 600 mL/min of oxygen (O2) in separated dual outputs, reaching 99.999% hydrogen gas purity.
Does the Echo Refresh also make hydrogen water?
No. The Echo Refresh is a dedicated molecular hydrogen gas inhalation generator. It produces high-flow gas for nasal cannula sessions rather than infused drinking water.
How long is the Echo Refresh warranty?
Echo backs the Refresh with an industry-leading 10-year warranty covering internal PEM electrolysis cells and power components.
