What Echo Water actually sells
[Echo Water](/brands/echo-water) describes itself as a leading hydrogen therapy company, and its catalog backs that framing up: 13 distinct standalone products spanning a portable hydrogen bottle, countertop and whole-home hydrogen water machines, a hydrogen bath machine, a hydrogen inhalation machine, a standard reverse-osmosis filtration system, and a hydrogen prebiotic drink mix.
This review covers the full standalone lineup, not the bundles the brand also sells, which mostly combine two already-listed products at a bundled price.
ECHO Flask: the entry point and bestseller
At $299.99, the ECHO Flask is the lowest-priced item in the catalog. Per the product page at the time of this review, it's also the bestseller, with 535 reviews averaging 4.6 out of 5 stars. It's a 12oz portable bottle stating an 8PPM hydrogen infusion output, one of the more specific concentration figures we found printed directly on a product page in this category.
No multi-thousand-dollar machine required. For anyone wanting to try hydrogen water, this is the natural starting point in the lineup, and it's the product we'd point a first-time buyer toward.
The machine tier: Flow, H2, One and Ultimate
Moving up from the bottle tier, Echo Water sells several countertop and home hydrogen water machines at meaningfully different price points. The ECHO Flow runs $1,999.99, reduced from a stated $2,499.99 at the time of this review. The ECHO H2 sits at $2,999.99, and the ECHO Ultimate at $4,999.99.
The ECHO One, priced at $3,499.99, was listed as a waitlist item at the time of this review, alongside the ECHO Forty tumbler. Across this tier, the core value proposition is delivery capacity and format rather than a fundamentally different hydrogen-generation mechanism from the Flask.
Bath, inhalation, and whole-home: the top of the range
At the top of Echo Water's range sit the products aimed at whole-household or specialized use. The ECHO Revive, a hydrogen bath water machine, and the ECHO Refresh, a hydrogen inhalation machine, both run $5,999.99 (Revive reduced from a stated $7,499.99). Whole-home options include the ECHO Whole Home Water Filter at $3,499.92 and the considerably larger Echo Whole Home RO System, the single most expensive item in the catalog.
These represent a meaningfully different use case than the personal bottle or countertop machine tier: whole-household water treatment and specialized delivery formats (bath immersion, inhalation) rather than a glass of hydrogen water to drink.
| Product | Price | Format |
|---|---|---|
| ECHO Flask | $299.99 | Portable bottle, 12oz |
| ECHO Forty | $399.99 | Hydrogen tumbler |
| ECHO Flow | $1,999.99 | Countertop machine |
| ECHO H2 | $2,999.99 | Countertop machine |
| ECHO One | $3,499.99 | Home machine (waitlist) |
| ECHO Ultimate | $4,999.99 | Premium home machine |
| ECHO Revive / Refresh | $5,999.99 each | Bath / inhalation machine |
The reverse osmosis product: a different claim entirely
Worth separating out clearly: the ECHO RO at $699.99 is a tankless reverse osmosis filtration system, a standard water-filtration product without any hydrogen-specific claims attached. If your interest is simply cleaner drinking water rather than the hydrogen-antioxidant mechanism, this is the product in the lineup that addresses that separately.
For readers wanting the fuller picture on whether the hydrogen mechanism itself is worth the investment, our does hydrogen water actually work piece walks through the research base independent of any specific brand.
What we verified and what we couldn't
We directly confirmed that pricing is shown openly on every Echo Water product page, with some items (ECHO One, ECHO Forty) marked as waitlist rather than immediately purchasable at the time of this review. We also confirmed the specific 8PPM figure printed on the ECHO Flask's product page and the star rating and review count shown at the time we checked.
What we could not independently verify: the actual hydrogen concentration delivered in practice using an independent meter, or how consistently that output holds across a bottle's full charge cycle. Star ratings on a brand's own site also aren't independently audited the way a third-party marketplace's ratings are.
Should you buy from Echo Water?
If you're curious about hydrogen water and want to try it at the lowest financial commitment, the ECHO Flask at $299.99 is the reasonable entry point in this specific brand's lineup. The machine and whole-home tiers represent a considerably larger investment for benefits with a comparatively early-stage research base, discussed in full in our companion piece on whether hydrogen water actually works.
As with every hardware brand reviewed on this site, cost and evidence strength should both weigh into the decision, and the price tag here runs meaningfully ahead of where the current human research sits. The site's full evidence-graded guide library is a useful reference point for judging any product's price against its actual trial support.
