ECHO Flask Hydrogen Water Bottle

Hydration with a high-tech twist. The Echo Flask infuses your water with molecular hydrogen on the go, so you can swap single-use bottles for one rechargeable flask you'll actually want to refill. We love that it makes a wellness ritual genuinely convenient — fresh hydrogen water at your desk, the gym, or on the road — without the plastic waste. A clean-living staple for anyone who takes their water seriously.

Fill the Flask with water up to the top of its shoulder — never run it dry. Purified or distilled water gives the best results. Secure the lid, then start a hydrogen cycle (about 5–7 cycles of 10 minutes, or 3–4 cycles of 20 minutes, per full charge). Drink the hydrogen water as soon as it's ready, ideally within 30 minutes, since molecular hydrogen escapes over time. To open, hold and release the pressure for a few seconds, then press the sides of the lid and twist counterclockwise. During the first week of regular use, the Flask builds pressure and bubble production improves. Rinse after use and wash occasionally with mild soap; descale with a 1:3 mix of white vinegar or citric acid to water.
