Which of the three should you choose?
Choose the HERO Inhaler 2000 if you want a same-class alternative to the Echo Refresh at roughly half the price, with the full certification stack published as documents. Best for solo users and two-person households; the included Y connector supports dual-cannula sessions.
Choose the HERO Inhaler Pro 3000 if you want the highest published pure H₂ output in the range — 2,000 ml/min — plus two independent outlets for dual-user sessions, three-speed flow control, a built-in UV sterilisation lamp and 365-day continuous operation. Still $2,600 less than the Echo Refresh.
Choose the Echo Refresh if the 10-year published warranty and 60-day money-back guarantee outweigh the ≈US$2,600–$3,700 price premium and the absence of published CE / FCC / RoHS / ISO certificates on the product page.
FAQ
How does the HERO Inhaler 2000 compare to the Echo Refresh on pure H₂ output?
The Echo Refresh publishes up to 1,800 ml/min hydrogen output. The HERO Inhaler 2000 publishes 1,200 ml/min pure H₂ (with 600 ml/min separated oxygen for a total 1,800 ml/min at the membrane, 2:1). Where the HERO Inhaler 2000 wins outright is price and certifications: US$3,897 vs US$7,499.99, with published CE, FCC, RoHS, ISO 9001 and ISO 13485. Figures published as of July 2026 — confirm current specifications directly with each manufacturer.
How does the HERO Inhaler Pro 3000 compare to the Echo Refresh?
The HERO Inhaler Pro 3000 delivers 2,000 ml/min pure H₂ — about 11% more pure hydrogen than the Echo Refresh's published 1,800 ml/min — plus three independent user outlets, three-speed flow control, a built-in UV sterilisation lamp and 365-day continuous operation without a water change. Price is US$5,697 vs US$7,499.99 for the Echo Refresh. Figures published as of July 2026.
Which machine has the longer warranty — and does that mean it lasts longer?
The Echo Refresh publishes a 10-year warranty. The HERO Inhaler 2000 and HERO Inhaler Pro 3000 both carry a 24-month manufacturer warranty from delivery. Warranty length and service life are different things: the PEM electrolysis stack inside every HERO Inhaler or HERO Inhaler Pro machine is rated for 10,000 hours of continuous operation, which equates to 10+ years at 45 minutes per day of use. The engineered lifespan of the machine is comparable — what differs is the length of the manufacturer-covered repair window. Weigh that against the ≈US$2,600–$3,700 lower price and the published CE / FCC / RoHS / ISO 9001 / ISO 13485 certificate stack.
Which certifications are published for each machine?
The HERO Inhaler 2000 and HERO Inhaler Pro 3000 both publish CE, FCC Part 15 Subpart B (test report LST250598095FR), RoHS, ISO 9001 and ISO 13485 certificates on the /certifications page. The Echo Refresh product page does not publish these certificate documents. General wellness devices — certifications describe the hardware and manufacturing process, not medical or therapeutic status.
Do the HERO Inhaler 2000 and HERO Inhaler Pro 3000 ship to the USA?
Yes — both ship free to all 50 US states with duties and taxes prepaid at checkout. The price you see is the price you pay: no customs bill on arrival. Typical delivery is up to 14 business days from order.
