Product Details

Inside every Echo device is special technology that turns normal water into hydrogen-rich water.

At the center is the Echo Hydrogen Generator. It uses two titanium plates coated with platinum and a thin proton exchange membrane between them. These laboratory-grade materials are chosen because they are strong, clean, and safe.

The proton exchange membrane was first made for NASA. Today, it’s used in hydrogen cars and other advanced machines. It lets pure hydrogen gas mix into your water while the oxygen is released into the air.

Our carefully shaped plates make sure the electric current spreads evenly, without heat or damage. That means the Echo Hydrogen Generator makes hydrogen faster and more efficiently.

Every part is built from laboratory-grade materials and made to last a long time—so you can always count on clean, high-quality hydrogen water.

Lab Results

The ECHO Hydrogen Flask has been lab‑tested and certified by H2 Analytics (Report H2AR‑250116‑1, dated January 16, 2025). Using gas chromatography testing on distilled water, the Flask consistently delivered 6.07 mg/L of dissolved hydrogen after a 10‑minute cycle and up to 8.25 mg/L after 20 minutes—well within the highest range of tested levels.

The US Food and Drug Administration has recognized hydrogen gas as a food additive is generally recognized as safe. The research confirms that hydrogen water is safe to be consumed. The ECHO Flask currently has a valid certification status by H2 Analytics in conformance with IHSA and US EPA standards. Registration# 24-0701-1-PB

Turn water into hydrogen water

Inside every Flask, is a specially designed membrane originally designed by NASA to carefully split water apart — releasing pure hydrogen, the same tiny spark that powers stars and helps your body work at its best.

Feel Better. Do Better.
Supercharge Your Metabolism

The smallest molecule in the universe, Hydrogen has been studied for its ability to support healthy energy metabolism and redox balance—two key drivers of stamina, metabolic efficiency, and humans who push harder and go further.

Upgrade Performance

Fuel your cells by supporting the systems behind endurance and recovery. By helping your body manage oxidative stress, it promotes better performance under pressure—whether you’re crushing a workout, a deadline, or both.

Support Whole-Body Vitality

Resilience isn’t optional—it’s your edge. Hydrogen water can play a role in cellular signaling, stress recovery, and aging resilience. When your cells bounce back faster, so do you. Stay sharp, stay strong, and live fully charge

Recover at the Cellular Level

Real recovery starts at the source. Hydrogen-rich water is being explored for its potential to support the body’s natural repair processes. Whether you're training, fasting, or just demanding more from life, hydrogen is your quiet recovery ally.

Gut Health Meets Immune Support

Your gut isn’t just about digestion—it’s a command center for immunity, energy, and mood. Research suggests hydrogen may support gut balance and reduce oxidative load, helping you feel more aligned from the inside out.

Gain Clarity & Focus

Hydrogen has been studied for its ability to help the body manage inflammation and oxidative stress in the brain—factors that influence focus, alertness, and mental endurance. Stay in the zone, longer.

FAQs

What is hydrogen water?

Hydrogen water is regular water infused with extra molecular hydrogen gas (H₂).It’s produced through electrolysis or by dissolving magnesium-based stick packs, allowing water to retain dissolved hydrogen that may offer antioxidant properties.  

What are the benefits of hydrogen water?

Emerging research suggests molecular hydrogen may reduce oxidative stress, thereby enhancing athletic recovery, improving cognition, and reducing inflammation, among other benefits. However, results are preliminary and not definitive.

How many PPMs of hydrogen does the Flask produce? 

The Echo Flask generates up to 6 PPM of dissolved hydrogen from a 10‑minute cycle and up to 8 PPM in a 20‑minute cycle.

H2 Analytics Report

How do you use the ECHO Flask?

Remove the cap and add plain water (ideally DI or RO) to the flask until full. Use the touch screen to activate the ECHO Flask cycle. Inside the chamber, water is split into hydrogen and oxygen, and the proton exchange membrane (PEM) helps keep unwanted byproducts separated from the drinking water. Dissolved molecular hydrogen is then infused into the water in the form of nanobubbles. Because this process builds internal pressure, release the pressure valve located in the cap after each cycle before opening the bottle. For best results, drink your hydrogen-enriched water shortly after it is ready. Make sure to store your flask filled with water. Detailed instructions can be found in the User Manual.

How often do I use the ECHO Flask? 

Hydrogen doesn’t accumulate in the body; it’s active for a short window and then cleared. That’s why we suggest intermittent use, drinking 2–3 flasks per day spaced across the day. This approach mirrors how hydrogen is studied and how oxidative stress naturally fluctuates during daily life.

Who can benefit from Hydrogen Water?

Hydrogen water is intended for people looking to support overall wellness as part of a healthy lifestyle. It has been studied for its role in helping the body manage oxidative stress, which naturally occurs during everyday activities such as exercise, digestion, and exposure to daily stressors. Many people choose hydrogen water as a simple addition to their hydration routine to support balance and recovery, alongside habits like proper nutrition, movement, and rest. Hydrogen water is not a medical treatment, and individual responses may vary.

    Echo flask

    Very good costumer's service, when my first flask arrived I was unable to open it, I believe it was a cup malfunctioning. Company replaced the flask in no time. Only few questions ask and a photo was required.

    I just got the replacement so I'm not table to leave a full review but I can say that the replacement is working perfectly, lots of micro bubbles star forming almost instantly. Thank you

    Great!!

    The presentation of the Echo flask when I opened the box was so “classy.” The quick reference guide was easy to understand. I hope the results of drinking from the Ecko flask are as great as the delivery!!

    Amazing Bottle Echo

    I received the bottle yesterday and I’m feeling great using already. Very easy to set up and very user friendly. Takes only 10 minutes to make 10 oz of hydrogen water. I’d highly recommend it to whoever that’s interested especially those with kidney issues. I’m thinking about purchasing a second bottle for my daughter. Btw, they also take HSA payment. If the system doesn’t take the card at first, you can pay with your regular credit card then logon to your HSA account to claim the reimbursement.
