Supercharge your water with our best hydrogen water bottle.
Hydrogen-rich water is a selective antioxidant known to boost the effects of your workouts, fight free radicals, and kick your metabolism into high gear.
Transform ordinary water into antioxidant-rich hydrogen water that boosts energy and supports recovery.
CLINICAL-GRADE TESTED HYDROGEN CONCENTRATION
Ocemida OCE-6000 PRO (Nexis) is independently tested by H2 Analytics USA (Report#: H2A-24030702) - an official testing lab for the International Hydrogen Standards Association (IHSA).
➜THE FIRST 7TH GENERATION DEVICE WITHOUT ANY OBSTRUCTION ON THE MEMBRANE

Ocemida Keeps the Electrode Exposed - No Plastic Obstructions, No Hidden Mold.
Unlike others that trap bacteria and mold under this reinforcement, Ocemida's open-membrane design ensures easy cleaning, full visibility, and no risk of hidden contamination. Forgetting to disinfect once shouldn't destroy your device - with Ocemida, it won't.
REINFORCED HIGH-PRESSURE CELL
Higher pressure means better hydrogen dissolution and the OCEMIDA water bottle delivers one of the highest tested concentrations of molecular hydrogen on the market.
IMPROVED DESIGN
Large opening at the bottom and a big gasket (seal) make this model leak proof and easy to clean.
BUILT TO LAST
Reinforced metal housing meets extra-thick Tritan walls for unmatched durability that withstands years of daily use. Every component is precision-engineered to resist drops, impacts, and wear while maintaining peak performance through thousands of uses.

NEAR-UV SELF-CLEANING
Featuring a Platinum-iridium top layer, this membrane offers exceptional performance and is free from harmful chemicals (see heavy metals and PFAS certificates). The 405nm blue light keeps your water fresh for longer.

Benefits That Go Further
⠀
Brain health
DNA repair
Gut barrier integrity
Selective antioxidant
Brain health
Hydrogen-rich water has shown promise in preliminary studies* for potentially supporting brain health through its antioxidant and anti-inflammatory properties. Some research suggests that molecular hydrogen may help protect neurons from oxidative stress, potentially improving cognitive function and reducing the risk of neurodegenerative disorders, though more comprehensive human trials are needed to confirm these effects.
*ncbi.nlm.nih.gov/pmc/articles/PMC9979207
DNA repair
There have been some studies* investigating the potential effects of molecular hydrogen on DNA, including possible DNA repair mechanisms.
Preclinical research suggests hydrogen might reduce DNA oxidative damage but human effects are not yet proven.
*pubmed.ncbi.nlm.nih.gov/33925430
Gut barrier integrity
Studies* suggest that the molecular hydrogen in hydrogen-rich water may help strengthen this barrier by reducing oxidative stress and inflammation in the gut lining. This could potentially prevent the leakage of harmful substances into the bloodstream, a condition known as "leaky gut."
Based on preliminary research, hydrogen water may support the growth of beneficial gut bacteria, further contributing to a healthier gut environment.
*ncbi.nlm.nih.gov/pmc/articles/PMC10871146
Selective antioxidant
As the smallest molecule in the universe, H2 can easily penetrate cell membranes and access intracellular compartments, including mitochondria. Its antioxidant action is thought to be selective, primarily targeting highly reactive oxidants like hydroxyl radicals and peroxynitrite without interfering with beneficial reactive oxygen species involved in cell signaling.

How We Made a Better Hydrogen Water Bottle
🚀 Newest Technology
The Ocemida 6000 Pro uses the latest smart design to make hydrogen water better and safer.
It has a special shape inside (called a conical hole) that helps tiny gas bubbles escape easily during electrolysis (the process that makes hydrogen).
It also has a strong felt layer made with platinum and iridium that keeps the membrane away from the drinking water. This is much safer than older designs that let unsafe materials (like PFAS) touch the water.
This design helps:
• Bubbles come off faster
• The machine work more smoothly
• The parts stay clean and working longer
🧼 Easy to Use and Clean
Other bottles have a small, narrow opening that makes them hard to clean and easy to break.
The Ocemida 6000 Pro has a wide opening, so it’s:
• Much easier to wash
• Doesn’t need parts changed often
• Doesn’t leak
• Still keeps pressure controlled and safe
This makes it super simple for daily use!
✅ Safe and Built to Last
The Ocemida 6000 Pro was made with safety first.
Every part is:
• Tested in labs
• Checked regularly for quality
• Backed by full safety paperwork
You can trust it to work well and last a long time.

Do i need to change or to replace anything in a hydrogen water bottle?
There are no filters or parts to be replaced in a hydrogen water bottle.
How long does the hydrogen concentration last in the bottle?
The hydrogen concentration in an unopened bottle can remain stable for up to 24 hours. However, once the bottle is opened and the pressure is released, the hydrogen content begins to decrease. The rate of decline is approximately 500 parts per billion (PPB) per hour.

What kind of USB charger can be used?
Most of our devices include a USB charger and cable. If your package doesn't contain one, please use only a standard slow charger, as speed chargers aren't supported and may damage your device. International customers should always use the provided charger with an appropriate plug adapter. If your country's voltage differs from 110V 60Hz, please contact us before charging to ensure safe operation and prevent potential damage to your device.
What makes this PEM safe?
Featuring a Platinum-iridium top layer, this membrane offers exceptional performance and is free from harmful chemicals.
The advanced Solid Polymer Electrolyte (SPE) and Proton Exchange Membrane (PEM) technology play a crucial role in the hydrogen generator. Through a sophisticated electrolysis process, this technology efficiently splits water into hydrogen and oxygen gases. The resulting hydrogen gas is then infused into the water, producing antioxidant-rich, energy-giving water with maximum bioavailability.
During this process, the system effectively expels any byproducts such as Ozone, Hydrogen Peroxide, Chlorine and Hypochlorite ion ensuring the purity and safety of the water. This integration of cutting-edge materials and technology not only enhances performance but also ensures the water is both potent in its benefits and safe for consumption.
What kind of water can be used?
Purified, distilled or reverse osmosis water should be used with this device for maximum performance.
Why is the bottle so small, can you make it bigger?
Hydrogen water bottles are intentionally small for several key reasons:
Concentration efficiency: Smaller volumes of water allow for higher hydrogen concentrations. This means you get more hydrogen per milliliter of water, maximizing the potential benefits.
On-demand supplement: These bottles are designed to be portable hydrogen generators rather than primary water sources. They produce a concentrated dose of hydrogen-rich water for supplemental use.
Distinction from regular bottles: The compact size differentiates hydrogen water bottles from standard water bottles, emphasizing their specialized function.
Optimal consumption: The smaller size encourages drinking the hydrogen-rich water soon after generation, when hydrogen levels are highest.
Practicality: A smaller bottle is more convenient to carry and use throughout the day for periodic hydrogen water consumption.

The Ocemida Professional is the most powerful unit on the market. Look carefully at H2hubb and you'll see it is the only one that can generate 1g of hydrogen within 5 minutes. ALL of the 'near' competitors take 10 min. to achieve this. With about 8 uses available per charge, and all studies based on getting 5g/day, this 5 yr. warrantied, beautifully made unit is as good as it gets. If you're serious about getting the benefits of Hydrogen water, there is no better choice.
Exceptional product! I have used many hydrogen products over the years. This is one my family can taste and feel the hydrogen bubbles coming from this water bottle.
Amazing product with above and beyond customer service!
⭐️⭐️⭐️⭐️⭐️⭐️
Hi there,
Very happy with the bottle and it's quality. Although there are ones on Amazon that look exactly the same for less money. Curious if these are the same as they look exactly the same. Otherwise a great product.
Thanks for this high quality device. It works great.
