I purchased the deluxe version as it charges up to 8,000 per billion parts hydrogen making this a powerful system. Do not trust any vendor here unless it is 3rd party verified as this one is. This disqualified 90% of the units. I usually use the charge at 4,000 ppb taking only 5 minutes to charge with a beep when ready. The usb charge lasts around 4-5 days. You do not leave plugged in while using. I consume 5-8 canisters per day and after 4 weeks it has held up well. When the system needs to be charged it blinks red. You only have a couple of minutes before shut off. All of the portable hydrogen machines use a small 8-10 ounce canister. This one is 10 ounces, but I wish it was larger. This model also contains a cannula for respiratory hydrogen therapy. It’s very easy to adapt and switch however there is a problem. The ionizer does not produce sufficient force to push hydrogen through tubing. This is going to be the case with all of these portable units. A simple resolution is gently pinch your nostrils closing around nasal piece requiring a forceful inhale. I have found this to be effective, but don’t expect the air to come pouring out like with oxygen.
Lastly, there was no customer service phone number only an email site. To their credit both questions were answered in the same day.
This is a pressurized system and I advise the deluxe unit as it is constructed to hold more pressure and will surely last longer as well as take less time to charge. All in all I am very happy with the unit and would highly recommend it!

Revising my rating from one star to five stars after Purepebrix customer service contacted me and rectified the problem. They contacted me and readily apologized for the defect. They shipped me a new device at no charge, which runs perfectly okay with no leaks (video update attached). They promised to promptly investigate and resolve the leak issue so other customers do not encounter it. Overall, I think they were very open and sincere hence my decision to reward them with an excellent rating. 8/27/2025 Started leaking between the cup and the base about 30 seconds to completion of a 10 minute run. Pic attached. I thought it was a fluke the first time so I ran it again and got the same result. Seems the pressure built up in the cup initiates the leak that late in the run. In case you’re thinking the cup wasn’t screwed on tight enough, I couldn’t have screwed it on any tighter without breaking the device. It screws on to a hard stop and wouldn’t go any further beyond that. Suffice to say it was returned in short order back to sender.

This is only bottle (of four that I tested) that met all the claims for H2 content in the water. I used both an analytical H2 meter and molecular hydrogen test reagent (blue water test) with various types of water and found it consistently meets claim of 2000+ ppb for a 6 minute production time. Filtered tap water using a Zero filter provided consistent results with no taste or odor. Distilled Water and Spring Water also worked and provided similar results.

I filled the bottle to the top line just below where the cap secures so little room for extra gas production. The very tiny nano bubbles are visible and remain suspended throughout the volume of water during and after production. The lid keeps it pressurized and after an hour maintains same level of H2. Once the lid is removed it slowly releases hydrogen gas so need to drink within a half hour. Empty stomach with no food for 30 minutes works well but not required. it is the gaseous hydrogen that quickly enters into bloodstream and can be easily absorbed by cells to anti-oxidize free radicals. Results are particularly noticeable after exercise or if fatigued.

I heard the good benefits of the electrolyze hydrogen water and get one to try out. At first i really don’t know whether it will work or not but i can feel the difference when it was making the hydrogen water, because when i open the cap, i felt the pressure was released. After using for almost a month, i just get use to it and i can feel a bit different with the water taste from the bottle compared to the water came out from the filter tap. The bottle has 2 settings. One is for 6mins and the second for 12 mins to create the hydrogen water. The longer we run the bottle is the better electrolyzed hydrogen molecules in the water. The package also came with a bottle adapter for us to put a regular bottle on to make it electrolyzed. My wife saw the bottle then did a bit research on the electrolyte hydrogen water and knew all the benefits of the water. she took my bottle and keeps using it every now. 😅

Very nice but the charging capacity not good also your hands slip when opening and closing cap and the bottom part very slippery but it makes high level hydrogen water !!!
