Please do not pour milk, tea, fruit juice, and other liquid to make hydrogen. Pure water, mineral water, and tap water all can be electrolysis.2. It’s better to drink all the hydrogen water within 30 minutes or produce again. 3. Please reserve 1cm space of the bottle (keep the water level 1cm lower than bottle mouth) when making hydrogen, because the air pressure difference between inside and outside of bottle after hydrogen making will cause the bottle cap is a little tight to open.4. When there is no water in the cup, please do not turn on the power. The cup cannot be turned on and the metal chopsticks cannot be placed in the cup; if you accidentally press it by mistake, long press the power button Exit electrolysis.
