Hydrogen Inhalation Machine Buyer's Guide

This sets output. One person = 900–1200 ml/min. Two people = 1200–1800 ml/min. 2–3 people or a treatment room = 3000 ml/min. Buying above your true concurrent count wastes money on unused capacity.

A professional-grade inhalation machine delivers pure hydrogen from a PEM electrolysis stack. HHO devices output a mixed gas that is not the same product and is not what published hydrogen inhalation protocols reference. This distinction matters more than any output number.

Look for independent CE, FCC and RoHS test reports covering electrical safety, EMC and hazardous substances. ISO 9001 manufacturing behind the build. Certifications describe hardware; they are not medical registration — but their absence is a red flag.

Direct manufacturer support beats a distributor claim form every time. Ask specifically: who answers the phone if something goes wrong, and where do parts come from? A one-line answer is the correct answer.

Look past the sticker. No proprietary consumables, multi-year service intervals on the stack, and a real 24-month warranty put total cost far below devices that sell cheap and consume filters or cartridges every quarter.
