Your Hydrogen Water Bottle is made of durable, eco-friendly Borosilicate glass, so please remember that just like other glass products, you should always handle it with care. Your bottle has a convenient carry handle so you can take it wherever your day takes you. We do not, however, recommend putting your bottle in your handbag or backpack as there are often other objects in there that can damage or break it. We recommend storing your bottle with the lid off. This will help keep your bottle looking and smelling fresh. Allow your bottle to air dry completely with the lid open. This will help to avoid unwanted moisture build up in your bottle and around the seal. Avoid using fizzy liquids such as mineral water and soft drinks as this can cause excessive pressure build up in your bottle which can lead to breakage. Make sure you fill your bottle to the fill line with purified water. Follow the instructions for your unit on how long to wait for the hydrogen water to convert. Hand wash your bottle with warm soapy water. Do not put your bottle in the dishwasher. Do not put your bottle in the freezer. Do not pour boiling/scolding water into the unit. If you're in an area with hard water - descale your unit at least once a month. To Descale: Pour 1/4 of distilled white vinegar over the titanium plates in the center of the base. Ensure they're fully covered. Let the vinegar sit for 12 hours and rinse well. For any further questions on how to care for your bottle please contact our support team at hey@hfev.com
