All of our hydrogen water bottle products use a Proton Exchange Membrane (PEM) paired with a Solid Polymer Electrolyte (SPE) electrolysis to split H2O and produce pure molecular hydrogen at medium to high concentrations.

Yes. The Original, Pro, and Hydrogen Water Machine are made from strong food-grade BPA free borosilicate glass.

Per customer request - have hqve one model in a plastic format. The Titan Series is made from a BPA and toxic plastic.

All of our products have their own key differences. Each one produces molecular hydrogen gas.

All are built with the same quality expectation. The primary difference between products are water capacity, hydrogen output, and hydrogen capacity levels (or a combination thereof).

For example - The Original Hydrogen Water Bottle has the lowest output and concentration (as compared to The Pro Series). The Titan Series has a higher liquid volume.

When sealed - the maximum efficacy of molecular hydrogen gas is approximately 15-30 minutes.

When you're ready to drink more hydrogen water - simply press the power button and the bottle will produce more hydrogen gas to drink.

Absolutely. In fact - we have the Hydrogen Water Machine specifically for this use case.

For maximum efficacy, transfer freshly hydrogenated water into you glass or stainless steel vessel immediately before consuming.

Although the concentration of Hydrogen drops after 15-30 minutes - it's worth noting, that hydrogen gas will remain present and testable in the water for roughly 12 hours.

Remaining Oxygen in the sealed bottle is vented so only pure molecular hydrogen becomes infused with your water.

The the Pro and Titan series, the O2 gases are vented through a special port. In the Original and Water Machine - the gases are vented through the lid.

Your Hydrogen Water Bottle is made of durable, eco-friendly Borosilicate glass, so please remember that just like other glass products, you should always handle it with care.

Your bottle has a convenient carry handle so you can take it wherever your day takes you. We do not, however, recommend putting your bottle in your handbag or backpack as there are often other objects in there that can damage or break it.

We recommend storing your bottle with the lid off. This will help keep your bottle looking and smelling fresh. Allow your bottle to air dry completely with the lid open. This will help to avoid unwanted moisture build up in your bottle and around the seal.

Avoid using fizzy liquids such as mineral water and soft drinks as this can cause excessive pressure build up in your bottle which can lead to breakage.

Make sure you fill your bottle to the fill line with purified water. Follow the instructions for your unit on how long to wait for the hydrogen water to convert.

Hand wash your bottle with warm soapy water.

Do not put your bottle in the dishwasher.

Do not put your bottle in the freezer.

Do not pour boiling/scolding water into the unit.

If you're in an area with hard water - descale your unit at least once a month.

To Descale: Pour 1/4 of distilled white vinegar over the titanium plates in the center of the base. Ensure they're fully covered.

Let the vinegar sit for 12 hours and rinse well.

Yes. There has been zero documentation that says drinking hydrogen-rich water is unsafe during pregnancy.

Although it is safe, however, we don't know your individual circumstances, so we higly we recommend consulting with your healthcare provider before changing your diet during pregnancy, especially when consuming products with added supplements or substances like hydrogen-rich water. Your healthcare provider can provide the most accurate and up-to-date information based on your health and circumstances.

Our advanced proton exchange membrane technology is compatible with all varieties of potable water.

Including: Unfiltered tap water, filtered water, reverse osmosis (RO), natural spring, purified, and even well water.

If you use hard water (i.e. tap or well) - please make sure to descale your water at least once a month to lengthen the life of the product. For instructions, please see "How Do I Clean My Bottle" above.

If you received your bottle or pitcher and it does not produce hydrogen bubbles, or it stopped. Fill your bottle or pitcher with warm water and allow the MEMBRANE located at the base to soak in water for 3-4 hours, in that time run the bottle or pitcher multiple times. This will help prime the proton exchange membrane which may have dried out enough stopping it from working as it should.

While you can use either - we recommend room temperature or cold water (iced is fine too!).

DO NOT pour boiling hot water in your bottle or pitcher, as it may cause damage to the proton exchange membrane (PEM).

Doing so will void your warranty.

Generally - you can expect to generate hydrogen 15-20 times per charge. It depends on the unit you have purchased, so please refer to the individual product page for further information.

Utilizing the supplied USB charging cable - you can expect 6-9 hours for a full battery charge.

Nope! Welcome to Hydro Fever - where our products are built with this in mind.

Our bottles are reusable, rechargeable, and create non-stop Hydrogen Water for years to come without the need of replacement accessories.

According to research - patients and athletes that consumed 4-5 bottles per day (about 60 ounces) of hydrogen-rich water achieved the optimal results/benefits within 4-6 weeks.

Your mileage may vary depending on your own physiology.

Yes, there is a difference in taste.

Our customers have reported that their water has a better taste after being run through their ionizing water bottle or pitcher than before
