VEVOR Hydrogen Inhalation Machine, 99.99% High Purity Hydrogen Inhaler, HO-Separated 1500ml/min (1000 H+500 O) Dual Port Hydrogen Oxygen Inhaler, Hydrogen-Rich Water Generator with Wheels for Home

I bought this because it was open box discount. I had been researching molecular hydrogen inhalation for MS I don't regret it 💯

Initially, the machine kept overloading at startup, but I’ve owned other hydrogen devices before, and they all behave the same way. During the first hour, they start, then stop—you just have to keep pushing “start”. After 30-45 mins, this one eventually began running consistently. I can confirm that. The flow feels very strong, so the advertised output seems accurate. I also tested the gas, and it’s definitely hydrogen. Overall, you won’t find a device like this—with this kind of performance and a protection plan—for such a low price in the United States.

Vevor is using an AI system to respond to warranty requests. My hydrogen generator seized up and tripped a circuit breaker. I reset the breaker, and as soon as I pressed the power switch, the circuit tripped again. A couple of hours later, it cooled down and restarted. It is under warranty, but an AI system keeps insisting that I send a video and audio recording showing the problem. The best I could do was send them a picture with the machine turned off, but that isn’t enough to get past the AI gatekeeper. This has been going on for over a month, and I've yet to reach a human. I'm not asking for a replacement, only an extended warranty for when it most likely will seize again - permanently.

This machine is outstanding and I would recommend it to anyone.

It is a work horse but can’t make hydrogen water that easily. It resolved my headache after alcohol exposure. Overall is good, I wish there was a better manual how to open it to change the filter.
