Looking for the exhaustive spec sheet with every published figure side by side, including the QY-A3000 as a third option? See our Echo Refresh vs QY-A1800 & QY-A3000 full specification comparison — that page is the reference source. This page is the shorter, decision-aid version: what actually matters when you're choosing between QY-A1800 and Echo Refresh specifically.
The comparison here is about the metric that actually matters for inhalation: gas output at the point of production, not a dissolved concentration in a glass of water.
Why inhalation is measured differently
Drinking-water hydrogen products are compared on dissolved concentration (ppm/ppb) — a figure that depends on glass size, water volume, and how long the water sat before drinking. Inhalation sidesteps all of that. What matters is the gas itself: flow rate (how much hydrogen the machine produces per minute) and purity (how much of that gas stream is actually H₂, versus contaminants). Both figures are fixed physical properties of the machine, not variables that shift with how someone uses it — which makes this a more stable basis for comparison than a dissolved-water claim. For the wider primer on the field, see what a hydrogen water machine is and how it works.

Where the real differences are
Peak flow rate is genuinely matched at this tier. Both machines top out at 1,800 ml/min of hydrogen — this isn't a case of one brand overstating a spec against a modest competitor. If raw hydrogen flow rate is your primary decision factor, these two are evenly matched.
Echo's purity claim is marginally higher — 99.999% versus 99.99%. That's a real, if small, difference on paper. Worth noting: purity figures at this level are typically stated by the manufacturer rather than independently re-verified by third parties in most of the sourcing we could confirm for either brand, so treat both numbers as manufacturer-stated rather than independently audited unless you can find a specific lab certificate.
Echo's H₂:O₂ output figures don't match simple water-splitting stoichiometry. Electrolysis of water naturally produces H₂ and O₂ in a 2:1 ratio. Echo's published specs list up to 1,800 ml/min H₂ against up to 600 ml/min O₂ — a 3:1 ratio. The most likely explanation is that these are independently adjustable maximums on separate channels rather than simultaneous fixed outputs from a single stoichiometric reaction, but Echo's public materials don't clarify this directly, so it's worth asking before assuming either interpretation.
Dual-user capability is a genuine Echo Refresh advantage. Two separate H₂ outputs mean two people can use the machine at once — a real practical feature if you're buying for a household or shared space, and not something QY-A1800 offers in single-user configuration.
CE, FCC, RoHS and FDA certifications are not listed on Echo Refresh's current product page. Echo's own support documentation lists those certifications specifically for the previous Refresh model. The current model's own product page does not list any of them — a direct, dated observation of what appears on Echo's own live page at time of review, not a soft caveat. Worth confirming directly with Echo before treating current-model certification as settled rather than assuming it carries over from the prior generation.
Warranty length clearly favors Echo, and this one's confirmed. A 10-year warranty is stated directly on Echo's own current product page — a real, substantial advantage over a 12-month standard warranty, worth acknowledging plainly rather than downplaying.
The price gap is the largest single difference between these two machines. Echo Refresh is $7,499.99 USD — roughly 2× QY-A1800's $3,777 USD, for a machine matched on peak hydrogen flow rate (both top out at 1,800 ml/min). Some of that gap is explained by the dual-user capability and the longer warranty, both genuine features. Whether it's explained entirely by those two things is a fair question for a reader to weigh for themselves — a single-user machine at roughly half the price, with the same peak flow rate and a marginally lower (but still very high) purity figure, is a substantively different value proposition even if it doesn't include Echo's specific advantages.
One correction worth noting on sourcing consistency: an earlier version of this comparison cited a "30 to 60 minute" timer range for Echo Refresh from a third-party reseller listing. Echo's own current product page states the actual range is 30 to 360 minutes — confirming the reseller listing, not Echo's own site, was the outlier here.
The honest bottom line
At the 1,800 ml/min tier, both machines are genuinely comparable on raw output, with Echo holding a marginal purity edge, a confirmed 10-year warranty, and a real dual-user advantage. QY-A1800 holds a clearer, single-source, third-party-manufacturer-verified spec sheet with no internal inconsistencies across resellers, at roughly half of Echo Refresh's price. If simultaneous two-person use and a decade-long warranty justify the premium for you, that's a legitimate call — but it's worth making with the actual numbers in front of you rather than assuming price differences this large are explained by specs alone.
