STRONGER
Unmatched hydrogen levels and powerful design.
Packing an advanced proton generator into such a small form factor was no easy feat. Not to mention up to 8 ppm of hydrogen, which would burst ordinary thin-skinned bottles. Experiencing enhanced cellular function, faster recovery, and better overall performance has never been easier.
SMARTER
Don’t settle for a dumb bottle.
The Echo Flask tracks your daily hydration stats and cycle — plus hydrogen potency, and provides personal notifications to help you reach your goals. Manage your flask with its intuitive touch screen, or interact with it from your phone. Say “hello” to premium hydration.
We hate bad water bottles, too.
Our smart bottle is accessible and durable. Its ergonomic design fits your hand or cupholder, with a quick-open lid for easy access. A textured surface prevents slips, and its tough, BPA-free materials withstand accidental drop tests without breaking or spilling—perfect for any adventure.
Health and hydration are finally connected.
Tracking your water intake shouldn’t be this hard. The Echo Flask App automatically records how much you’re drinking and syncs with your other health apps. This integration provides a comprehensive view of your wellness, allowing for smarter, more personalized recommendations.

Hydration doesn't have to be a solo journey. The Echo Flask App lets you share your goals and progress with friends, creating a supportive community that celebrates your wins and keeps you motivated. Hydration just became a team sport.

Warranty Limitations & Exclusions
Non-Performance Components Disclaimer: Components that do not directly impact hydrogen production—such as the notification speaker, LED lighting, or other auxiliary features—are not covered under this warranty. These elements are considered non-essential to the core function of the device and may be subject to wear or damage due to environmental exposure (including moisture) or physical impact (such as movement causing internal components like the circuit board to shift). As long as the device continues to properly generate hydrogen, these non-performance-related components are not eligible for standard warranty coverage but would be covered under the Echo Care plan.
- The device's battery is not covered under the warranty; however, if you are experiencing an issue, please contact our support team.
- Accessories, such as the lid, seal/gasket, charging cord, and power block, are covered under warranty only within the first 30 days from the date you receive your product. If needed, you may purchase replacements from echowater.com after the specified timeframe has expired. Accessory replacement orders not covered under warranty will incur applicable taxes and shipping charges.
- The Echo Flask warranty does not cover issues related to the Echo Water App or firmware. The Echo Water App may occasionally experience temporary disruptions during development and updates. However, this does not indicate a defect in the bottle itself, as it will continue to produce hydrogen as intended.
- The audible pressure release sound may vary, become less noticeable, or disappear over time as the pressure release valve naturally softens with normal use. This is an expected design characteristic and does not impact hydrogen concentration or performance. Variations or absence of release sound is not covered under warranty.
- Minor moisture or small drips or "leaks" from the oxygen port are expected during normal operation and are not considered a defect. This may range from a small spot to the size of the flask base and occurs as a result of oxygen release during use and is not covered under warranty.
- Warranty coverage will be void if the product has been damaged, misused, or improperly maintained. You may find all product guidelines for use and maintenance in the Echo Flask™ User Manual.
Exclusions include damage from:
- Physical damage such as cracks, breaks, scratches, stains, or dents to the outer casing, lid, or display screen is not covered under warranty and may impact eligibility for coverage if it is determined that the external damage contributed to internal failure. Device repair for these incidents is not available. If your Flask arrives damaged, please report it to Echo Support upon receipt of delivery to obtain coverage under Echo Shipping Protection. We will require photos of the damage as well as photos of the shipping box your order arrived in to submit your claim.
- Damage resulting from exposure to harsh chemicals or from using substances other than water or approved cleaning agents as outlined in the Echo Flask™ User Manual.
- Staining or discoloration.
- Operation with water in the bottle or generator.
- Use or storage in excessively hot or humid environments.
- Prolonged exposure to the sun.
- Use or storage in refrigerator, freezer, or in extreme cold temperatures.
- Water or humidity damage to the electrical ports or the screen.
- Contact with insects or animals.
- Use with hard water.
- Physical damage or soiling, including bodily fluids.
- Theft or loss.
Maintenance-Related Exclusions
- The warranty does not cover issues that may arise due to unauthorized repairs or alterations.
- The warranty does not cover performance issues resulting from improper or infrequent cleaning. Conditions such as mold, mildew, residue or film buildup, or changes in taste or odor are not considered product defects and are typically caused by maintenance practices or water quality.

Refunds to the original payment method are not available under warranty.
Many common issues can be resolved without replacement through simple adjustments, software or firmware updates, or minor fixes that do not require warranty coverage.
Replacements
- One warranty replacement is allowed per purchased item lifetime. If the device has already been replaced under warranty, no additional full replacements may be available. If a replacement device is experiencing issues, please contact our support team for further guidance.
- All replacement products will carry the original warranty date, not the date you receive the replacement unit. The warranty period does not restart or extend when a replacement product is issued.
Testing Tool Disclaimer
- After-market testing meters and blue reagent tests are not accepted as proof for warranty purposes, as they do not accurately measure hydrogen levels.

Hydrogen water, made simple.
What is hydrogen water?
Hydrogen water is water infused with molecular hydrogen gas, also known as H₂. It is designed to be consumed as part of a daily hydration routine and is often used by people looking to support recovery, oxidative balance, focus, and overall wellness.
Why is it used for longevity?
Longevity routines are built around small, consistent habits that support the body over time. Hydrogen water fits naturally into this approach because it is easy to use daily and supports foundational wellness areas like hydration, recovery, cellular resilience, and oxidative stress balance.
When should I drink hydrogen water?
- In the morning as a hydration upgrade
- Before or after workouts to support recovery routines
- During the workday for focus and hydration support
- As part of a sauna, red light, or cold plunge wellness stack
- Anytime you want to make hydration more intentional
How does this fit with other CHH wellness products?
EchoWater pairs beautifully with the Core Human Health recovery stack. Use hydrogen water alongside sauna, cold plunge, red light therapy, and daily movement to create a more complete longevity ritual that supports hydration, recovery, energy, and restoration from the inside out.
Is hydrogen water a quick fix?
Hydrogen water is best viewed as a daily wellness habit, not a one-time quick fix. EchoWater compares the experience to a daily vitamin — benefits may build gradually over time, especially because many of the effects happen internally at the cellular level.
Curated by Core Human Health
A simple daily ritual with a longevity mindset.
Hydration is one of the most consistent things you do every day. EchoWater transforms that daily habit into a more intentional wellness practice — supporting recovery, focus, cellular resilience, and the long-term lifestyle CHH was built around.
“Invest in a recovery ritual you’ll return to.”
