Hydrogen Inhalation Machine HO-Separated 450/900ml/min Inhaler Dual-Port Adjustable, Hydrogen Water Generator, SPE PEM Water Ionizer

I just received my unit two days ago, so far I'm very happy. It has a high/low mode as you can see in the product description. It was simple to set up and seems to work great. It outputs either H or O2 or a mixture of the two, what they call "Brown's gas". Most of the websites I've read say that the combination of the two is even more beneficial than either on it's own so that's what I've been breathing.Pros: High flow rate. Can do H, O2 or a mixture. Works out-of-the-box. Essentially maintenance-free. Very nice looking finish, doesn't look like a science experiment like some others do :-)Cons: It's a little noisy, even when it's "off" one of the fans keeps running. The user manual is written in typical grammatically incorrect English, it's not horrible but they should hire an American to proof-read it for them ;-) The nasal cannula could be a little higher quality, it's typical quality but I wish it was a little softer.

I've had this for a few days and so far I really like it. Hard to say if it's having any health effects yet, but it definitely works as advertised. Product came missing a few non-essential accessories, but seller was really responsive and shipped those to me immediately.Only issues is there doesn't seem to be a way to get it to not beep loudly when the time expires. Also, its a bit bulky, but that's to expected from the item description and photos. I do wish it had a built in handle which would make moving it a bit easier.

The machine is quiet in my opinion and also quite sleek. A friend purchased for me to assist with cancer recovery. It’s almost impossible to tell if anything is happening as I cannot feel any type of air. Would love to understand this better if anyone has any experience.

I upgraded to this from a small hydrogen water system because it helps me with the brain fog but I had to drink too much water. I treat pots like an ischemic cascade/stoke and I found this machine actually helps relieve the pots itself. Lower hr jump and less head rushes.
