Frequently asked questions
KENCOS generates hydrogen through the electrolysis process. Electricity is fed to the tank where it splits the electrolysis liquid into oxygen and hydrogen. The gases then travel through a small tube and are inhaled. 8 ml of hydrogen gas is generated per minute.
Electrolysis liquid is necessary to produce hydrogen. Flavor cartridges add a nice element to practicing hydrogen inhalation for health, however, they are not necessary for hydrogen production.
After being fully charged, the battery will last 40 minutes if you use hydrogen only mode and 20 minutes if you use hydrogen + flavor only mode.
There is a 1 year warranty included. Keep the warranty certificate and proof of purchase. Please refer to the instruction manual for more warranty details.
First, turn on the device by pressing the power button three times in a row. Once the device is turned on, the battery level will be quickly displayed according to the color that lights up on the button. Blue = 80% or more, Green = 20% - 80%, Red 20% or less.
All ingredients within the flavor cartridges are completely safe for consumption.
The life of the flavor cartridge will largely depend on the strength and frequency of each inhalation.
If KENCOS is used five times a day for 5 minutes each time, the liquid should last approx. 6 days.
Each time the liquid is replenished, all the previous liquid must be discarded and the entire contents of the new bottle must be poured into the tank. It is important to never fill the liquid in parts, as this will affect the balance of the electrolysis liquid formula.
While hydrogen is completely safe to inhale, we insist that if you use it while pregnant or breastfeeding, consult your doctor first.
KENCOS can be enjoyed safely without restrictions and at any time of the day, however, as our research is based on using the device 5 times a day for 5 minutes each time, we recommend this use as the recommended one.
KENCOS will not cause any harm to babies or young children, however, as the inhalation action may seem inappropriate for younger ages, we recommend that you do not use KENCOS in the presence of babies and young children.
Inhale confidently but not too deeply for a few seconds per inhalation. It is particularly important not to inhale deeply when using flavor mode, as this can potentially burn the contents of the cartridge.
Hydrogen cannot be seen and has no taste. Whenever bubbles are generated in the electrolysis tank, this means that hydrogen is being produced. Use the flavor cartridges to visualize your inhalation experience.
The black cartridge simply acts as an object to block any gas escape and should always be installed when using hydrogen only mode. Do not use flavor mode with the black cartridge installed.
The black cartridge is a dummy cartridge needed to block the flow of hydrogen. If installed during flavor mode, the heater will not have any liquid to burn and therefore the device will automatically stop working.
