Use & Effect

Easy to use for various purposes

  • Prevents cell oxidation by drinking high-concentration hydrogen water on a daily basis
  • Since it decomposes hydroxyl radicals and optimizes the body, preventive medical effects can be expected.
  • Washing your face with hydrogen water has a beautiful skin effect.
  • Maintains the freshness of the ingredients, making your usual dishes even more delicious.

Doctors Man’s hydrogen water products are measured by gas chromatography for accurate performance values.

A.“ppm” is a unit of percentage. 1ppm equals to One-Millionth(≒0.0001%).
Saturated amount of hydrogen dissolved into water under 1 atmospheric pressure is 1.6ppm.
Hydrogen generates 28cc hydrogen per minute.
It discharges 1L hydrogen water in 1 minute and thus generation rate of hydrogen is 2.8% (28,000ppm).
This simply indicates hydrogen generation capacity. Dissolved hydrogen concentration of generated hydrogen water is about 1.0ppm

A.”+ h” is equipped with high performance carbon filter which rejects chlorine. Therefore, you can enjoy pure hydrogen water from tap water at home (drinking water only)

A.”+ h” is designed to use drinking water. Use of other liquid may cause malfunction. With RO water and hard water, hydrogen generation may become unstable and it may damage the generator. Water temperature should be 5-35 degrees.

A.Water tank capacity is 4L.

A.The  C (cleaning) button will blink after use of 30L water. Just press the  C about 3 sec. , device will start to clean automatically.

A.Many of electrolysis type hydrogen generation products have the risk to cause water quality turning acidic as the electrode contacts the water for long time electrolysis. While adapting same electrolysis method, however, “+ h” avoid this risk with platinum and make the contact time minimum. With this technology, “+ h” realize water quality remaining in neutral range. Find more information about Doctors Man patent technology on RESEARCH & DEVELOPMENT section.

A.”+ h” is manufactured and inspected in Japan.

A.Concentration of Hydrogen  gas dissolved in water will  drop gradually. We recommend  to drink immediately, but hydrogen generated by Plus H can remain maximum 8 hours till it disappears completely.

A.Accoring to IHSA (International Hydrogen Standards Association) standard, after much debate and consideration, IHSA suggests that the minimal amount of hydrogen should be established as a dose per day in a maximal volume of solution. The standard has been determined to provide at least 0.5 mg of H2 by ingesting a maximal volume of 1 L of product water, or 500 mL of specialty beverages. Hydrogen water generated by Plus H can reach the standard by taking 250ml per day.
