The device does not work and is turned off immediately even after pouring water into the water purifier.

If the device is turn off immediately it means that there is not enough mineral in water for electrolysis. Hydrogen is not generated from water from a reverse osmosis purifier. In this case, submerge the filter into the water from a purifier and operate the device after 30 minutes. Hydrogen water can be manufactured as minerals in the filter permeate.

The best water to manufacture hydrogen water is mineral water with a lot of minerals. Also, you may use water from a natural osmosis purifier to manufacture hydrogen water as it contains minerals.
