Features
Achieves a dissolved hydrogen amount of approx. 0.1 ppm*1, one of the best in the industry
Place the device in a 200 liter bathtub filled with hot water. After 15 minutes, the amount of dissolved hydrogen rises to approx. 0.1 ppm*1. The amount of hydrogen stays at 83% for 45 minutes after the device automatically shuts down, giving you ample time to enjoy your hydrogen bath.

Generates finer microbubbles at approx. 300 million bubbles per minute
Ultrafine micro-sized*2 hydrogen bubbles quickly dissolve into the water, clouding the bath right before your eyes. The hydrogen level remains consistent in the water for a long period of time. The hydrogen effectively warms the body, and even retains warmth and moisture after bathing.



- Test conditions: Subjects: 10 (5 adult men, 5 adult women), room temperature: approx. 22℃, humidity: approx. 50%, bath volume: approx. 200 L, bath temperature: approx. 40°C, time in bath: 5 minutes (Bath hydrogen generator (test device) turned on 10 minutes prior to bath. Left on for first 5 minutes of bath.)
- Test method: People took both regular baths and baths using the hydrogen generator. [Fig. 1] Thermographic image of surface body temperature 30 minutes after bath. [Fig. 2] Measurement of moisture level in the stratum corneum on the right calf after bathing.
- Testing organization: Japan Clinical Trial Association (general incorporated association)
The newly designed (3 layers x 4) electrode structure quickly produces hydrogen within the water.
The surface of the titanium electrode is coated in platinum, with three layers on all four sides. Optimally arranging the electrodes creates more than approximately 300 million bubbles per minute. The entire bath fills with hydrogen.

LED lights provide a relaxing sensation environment.
During operation, the LED color changes with each press of the button. The bath lights up from the bottom, creating an incredibly luxurious and soothing experience.

- Approx. 0.1 ppm of dissolved hydrogen: Value after 15 minutes of electrolysis in 200 L water at approx. 40℃. Study undertaken by Maxell. This value varies depending on conditions of use.
- Micro-sized: 1/1000 of a millimeter
