Portable hydrogen water generator breathing inhalation machine for health. Let’s start a new custom for health. New Portable Hydrogen Inhaler

Other common hydrogen inhalers are huge and too expensive to buy for individual. KENCOS was made as breakthrough product that can be inhaled sufficient hydrogen from portable sized device by the certified patent technology It can be inhaled hydrogen whenever and wherever and also have fun to use it with flavor that you like.

KENCOS represents the start of an era in which we inhale hydrogen gas as a new custom for maintaining our health. It enables us to inhale hydrogen gas directly through our mouths no matter where we are.

KENCOS was conceived for the purpose of ensuring that inhaling hydrogen for health becomes a familiar new custom. It is of a compact size that enables it to be carried around everywhere and it allows hydrogen to be inhaled through the mouth to enable use as a part of your everyday lifestyle. This high-quality hydrogen experience can be enjoyed at home or in the office, and it supports a daily sense of positivity.


Certified Health Improvement product

“Certified Health Improvement product” refers to machinery and equipment designed to improve people’s health, beauty and quality of life (QOL) and certified by The Japan Home-Health Apparatus Industrial Association.


Recommended by The Japanese Association of Preventive Medicine for Adult Disease

This recommendation means that The Japanese Association of Preventive Medicine for Adult Disease have recognized KENCOS as a product that can contribute to the spread of preventive medicine, meeting their strict screening criteria.

The unique technology of KENCOS

KENCOS produces molecular hydrogen via the process of electrolysis.

Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This process takes place within an electrolyzer.

Inside KENCOS’s tank are electrodes made of platinum and titanium. These carry the electric current and deliver them to the specially formulated electrolysis liquid solution. This solution contains sodium citrate and pure water. The sodium citrate is there simply to act as a conductor, which pulls in the electrical current, which in turn splits pure water into 66.6% hydrogen and 33.3% oxygen. As you breathe through the mouthpiece of the unit, you are directly breathing this gas into your lungs.

Electrolysis is the most practical way to produce hydrogen in inhalers as it avoids the need to store excess gasses and simply allows the user to inhale the hydrogen as it is produced.

A common question we receive is “Why can I simply not use tap water to generate the hydrogen instead of a specially formulated solution?”

The answer to this is actually tap water will certainly work in achieving electrolysis, however the danger with this is the tap water is not purified and will be contaminated, adding harmful contaminations to the gas that you inhale.

Pure water will not conduct electricity, so the electrolysis solution that KENCOS uses is pure water with just a small amount of sodium citrate to conduct the electric current.

What are the benefits of electrolysis?
In hydrogen inhalation devices electrolysis is preferred as this will generate pure hydrogen without emitting any harmful gases into the atmosphere, meaning KENCOS can produce hydrogen simply and effectively without any greenhouse gas emissions.

The science of electrolysis as well whilst very specific, is simple to understand and execute. This technology is utilized by KENCOS effectively to deliver hydrogen on the go.

Does the flow rate suffer due to KENCOS’s small design?
KENCOS came from the idea of being able to supply customers with a convenient method of hydrogen inhalation whilst still maintaining the benefits that can be felt from inhaling hydrogen from the large, non-portable machines. Knowing the flow rate would be lower, company maker cooperated with a national university In Japan to conduct research based on KENCOS’s maximum 8ml per-minute hydrogen flow rates.

The results show that as long as used regularly, hydrogen even at this flow rate can still potentially offer the refreshment effect.
