• Remember to ALWAYS recap your air tight water bottle when you are not directly consuming hydrogen rich water. (Hydrogen, an extremely light gas dissipates in just a matter of minutes -- if the cap is not on.)
   
• Do not place Hydrogen Water Stick near a flame or heat in a microwave oven
   
• Do not heat the Hydrogen Water Stick in kettle, rice cooker, pot or other such device.
   
• Do not add boiling water to the Hydrogen Water Stick that has placed in a container
  (heat resistance to 60° C)
   
• Use ONLY PLASTIC WATER BOTTLES or GLASS BOTTLES. Plastic water bottles with PET or bpaFREE ratings would be good considerations. If using glass, do not let stand unused for long periods of time (pressure from generated hydrogen gas may cause a glass bottle to break or the cap to forcibly fly off). A tight fitting lid is very important.
   
• DO NOT use any type of metal water bottle, they retard reactions.
   
• Filtered tap water is best for use. Do not use Distilled water. Minerals are necessary for good reactions.
   
• RO (reverse osmosis) water users please click here for additional info.
   
• Do not wash the Hydrogen Water Sticks with deterrents, benzene, thinner or any other volatile solvent (please refer to Care and Cleaning section for proper care and cleaning of your Hydrogen Water Stick.)
   
• Do not place the Hydrogen Water Stick in your mouth (be especially careful with small children and pets, as the Hydrogen Water Stick could become lodged in their throats)
   
• The Hydrogen Water Stick should only be placed in water - nothing else (not tea, juice, milk or any other liquid)
   
• Do not break, take apart, drop or provide any other strong shocks to the Hydrogen Water Stick.
   
• Once the Hydrogen Water Stick has been used, it should always be immersed in water from that point forward. and not exposed to air.
   
• You will never have to let you Hydrogen Water Stick "air out". This is to prevent the raw materials from becoming deteriorated through oxidation by exposure to oxygen in the air.
   
• The bottle cap should be stored on loosely if the plastic bottle is going to be stored form more than five days. (Do not make air-tight if storing more than a few days. (pressure from generated hydrogen gas could rupture bottle)

We are not responsible for any problems that might occur if the user ignores these cautions and uses the Hydrogen Water Stick improperly.

These Hydrogen Water Stick instructions will need to be read aloud to any visually impaired user.
