Ultra-high concentration nano-bubble hydrogen water. The premium hydrogen generator NEWJOY is also usable with convenient PET bottles. Purchased from Takara-ju Co., Ltd. ※ This is not the premium type that allows for hydrogen gas inhalation. Three reasons to choose NEWJOY (for drinking hydrogen water) 1. Industry's number one highest concentration Using a special electrolysis method, an ultra-thin PEM membrane (polymer electrolyte membrane) is used to separate high-purity hydrogen gas and oxygen. Achieves a high concentration of approximately 1.5mg/L in 5-minute mode and approximately 2.5mg/L in 20-minute mode. 2. Certified by international standards The international standard certification mark is created for consumers to ensure they use the correct hydrogen products. 3. One and only with patented PET bottle attachment With the PET bottle attachment (Patent No. 5799188), you can easily attach a PET bottle and generate hydrogen water while on the go. Startup confirmed. Please let me know if you have any questions in advance. Includes three dedicated attachments. The charger is your own.
