How much water does a Dr.wellness 3000ml hydrogen-oxygen machine need to add? How much water does it consume in one hour? How often do you change the water? 

When the water tank is filled with about 4 liters, it will stop automatically adding water. The machine consumes 130 to 150ml of pure water or distilled water per hour. When it consumes 1.5 liters, it will prompt that it is short of water and needs to add water to start. The water tank needs to retain 2.5 liters of water to protect the machine. Therefore, starting from the second time you add water, you only need to add 1.5 liters without pouring water and then adding water. The machine will also prompt that the water is full and automatically stop adding water.

If you use it every day, just add water when prompted.

If you have not used it for more than 15 days, please drain the water and add new water again.
