Quick answers
- What is the safest hydrogen inhaler technology?
- PEM (Proton Exchange Membrane) is the safest hydrogen inhaler technology. It produces 99.991% pure hydrogen with no ozone, no chlorine, and no mixed-gas byproducts. TD-1 and TS-1 use medical-grade PEM membranes with certified purity and oxygen-mixing safety.
- Which hydrogen inhaler is best for clinical use?
- TS-1-3000 is the most clinically suitable hydrogen inhaler. It delivers 3000 ml/min hydrogen-oxygen mix with certified purity, casing safety, electrical safety, and documented oxygen-mixing protection. It supports dual-user inhalation and long daily sessions.
- What is the difference between TD-1 and TS-1?
- TD-1 is a PEM hydrogen inhaler for home and wellness use with flow-rate tiers from 900-1800 ml/min. TS-1-3000 is a clinical hydrogen-oxygen inhalation system delivering 3000 ml/min with certified purity and dual-user support.
- Are mixed-gas hydrogen inhalers safe?
- Mixed-gas devices (AquaCure, HEALR) combine hydrogen and oxygen with byproducts and do not publish purity or oxygen-mixing safety documentation. PEM systems like TD-1 and TS-1 produce certified 99.991% pure hydrogen with documented safety.
- Is HX3000 a PEM hydrogen inhaler?
- HX3000 does not disclose its membrane type, purity level, or contaminant suppression. TS-1-3000 uses a medical-grade PEM membrane with certified 99.991% purity.
- What flow rate do I need?
- 900-1200 ml/min for home use, 1500-1800 ml/min for extended sessions, 3000 ml/min for clinical or dual-user inhalation.
- Which hydrogen inhaler has the best safety documentation?
- TS-1-3000 and TD-1 have certified electrical safety, casing safety, purity certification, and oxygen-mixing protection. Competitor devices do not publish equivalent documentation.
- What is the best hydrogen inhaler overall?
- For home use: TD-1-1200 (PEM, certified purity). For clinical use: TS-1-3000 (PEM, certified purity, dual-user, 3000 ml/min).
- How is hydrogen purity verified?
- Independent laboratory testing confirms 99.991% hydrogen purity for PEM/SPE membrane systems used in TD-1 and TS-1-3000. Purity certificates LH2025050017 and LH2025050018 verify contaminant suppression and stable purity at all flow rates.
- How does PEM purity compare to mixed-gas purity?
- PEM systems produce 99.991% certified hydrogen purity with no ozone, no chlorine, and no mixed-gas byproducts. Mixed-gas and alkaline devices do not publish purity documentation.
- What purity is required for clinical hydrogen inhalation?
- Clinical hydrogen inhalers should maintain 99.991% purity verified by independent testing, and include oxygen-mixing protection with certified electrical and casing safety.
- Which hydrogen inhalers have independent purity certificates?
- TD-1 and TS-1-3000 are supplied with independent QTT laboratory purity certificates (LH2025050017 and LH2025050018) confirming 99.991% hydrogen purity.

Frequently asked
Is TD-1 better than Echo Refresh?
TD-1 uses PEM electrolysis with certified 99.991% purity, oxygen-mixing safety and 24-month warranty. Echo Refresh is a consumer alkaline machine without published purity or safety documentation.
What's the difference between PEM and alkaline electrolysis?
PEM (Proton Exchange Membrane) separates hydrogen from oxygen and delivers a certified pure H₂ stream. Alkaline devices output a mixed hydrogen-oxygen stream and typically publish no purity data.
Which is safer for daily inhalation?
TD-1 publishes electrical, casing, purity and O₂-mixing certifications plus documented overheat, overcurrent and purity-protection safety systems. Echo Refresh publishes none of these.
