Osmio Duo Hydrogen Water Bottle 400ml

The Osmio Duo Hydrogen Water Bottle 400ml is a dual hydrogen water product that can be used for both enriching the water with hydrogen and for breathing hydrogen gas.

The product comes complete with UK Plug and USB Charging kit, the nasal cannula kit and another kit designed to enable you to use a standard sized off the shelf PET plastic water bottle too. This means you can use your Osmio Duo Hydrogen Water Bottle anywhere on the go, and even if you have to buy bottled water (which we all do sometimes, but we must avoid as much as possible for our environment) then you can still use that to generate the hydrogen.

The Osmio Duo only puts, and can only ever put pure Hydrogen H2 gas into the water. Oxygen is separated out. This means any kind of water can be used (i.e. tap water, mineral water, spring water, filtered water, osmotic or distilled water). Please note that the quantity of h2 can vary depending on the level of dissolved solids (TDS) in your water.

The Osmio Duo Hydrogen Bottle improves of the first Osmio Hydrogen Water Bottle, as it is made from high-quality glass and generates much higher concentration of hydrogen water than our old bottle and lots of other standard electrolysis bottles.

How long does hydrogen-rich water last?

After you have produced the hydrogen-rich water for the bottle it has a 2-hour half-life from the hydrogen in the bottle.  This means that after two hours half the hydrogen will be left in an open container that has not been disturbed, so we recommend you consume the water as quickly as possible and only produce as much as you are able to drink at that time.

Key features:

· Makes an ORP Value of -300 to -750 mV.

· Delivers an H2 concentration: 1100 to 2000 ppb (1.1 to 2.0 ppm) with a 7-minute cycle.

· Uses the latest Proton Exchange Membrane (PEM) and Solid Polymer Electrolysis (SPE) technology.

· Chlorine, Ozone, and Oxides - a built-in mechanism to separate and expel this from the bottle.

· Made of Borosilicate Glass and using the Platinum coated Titanium electrode. The lid and all other parts are plastic but have no contact with the water.

· Please note there is no manual included in the box and needs to be downloaded here or you can scan the QR code on the box.

Comes complete with:

Bottle Cap, Glass Bottle, Generator Cover, Rubber Plug, Generator Base, Generator Waste Cap, USB Power Cable with UK Plug, Bottle Adaptors (2 sizes included), Spare set of 3 washers for bottle head and between the bottle and the generator, 1 x Nasal Cannula.

Can we drink the hydrogen water after using the cannula to breath the gas?
Question by: Sonny on 22 Jul 2021, 19:11
yes, you can, however, water will not reach maximum saturation. For maximum saturation run the 7 min cycle with a full bottle, completely closed.

Is water produced by the duo classed as ionised water?
Question by: Adrian on 6 Sep 2022, 11:11
Water produced by the generator is Hydrogen Enriched Water

Water produced by the generator is Hydrogen Enriched Water. It has up to 2 ppm dissolved molecular hydrogen which is antioxidant.

what is the hydrogen gas concentration output in percentage through the canula?
Question by: Ali on 15 Aug 2021, 18:40
the flow produced by the bottle is 20ml per minute. We would recommend looking into Osmio Infinity - the system produces up to 830 mL/m of 66% hydrogen and 33% oxygen.

ONCE BEFORE DRINKING" (from manual) why not?
but for breathing more cycles are required.
Question by: ali on 15 Aug 2021, 19:08
You can run 2 cycles if you are drinking the water. You need to open the lid between cycles to avoid the build-up of excessive pressure. There is no benefit in running further cycles, as there will be no significant increase in H2 concentration.
