Echo Flask™ User Manual

---

Your Echo Flask™ may arrive with a small amount of distilled water—this is intentional! It’s part of the design to ensure optimal performance. 

If your Echo Flask™ arrives dry, NO WORRIES! It will simply require a 24-48-hour rehydration period. Fill the bottle with non-chlorinated water and let the internal membranes absorb moisture fully. During this time, you may notice the bubbles transitioning from sporadic large bubbles to a fine mist—this is entirely normal!

NOTE: It may take up to a week of consistently running cycles to get your Flask to achieve a steady flow of bubbles. If more than a week has passed and your bottle is still having trouble producing bubbles, please reach out to our customer service team at support@echowater.com for further assistance.

Your Echo Flask™ may arrive with a small amount of distilled water—this is intentional! It’s part of the design to ensure optimal performance. 

If your Echo Flask™ arrives dry, NO WORRIES! It will simply require a 24-48-hour rehydration period. Fill the bottle with non-chlorinated water and let the internal membranes absorb moisture fully. During this time, you may notice the bubbles transitioning from sporadic large bubbles to a fine mist—this is entirely normal!

NOTE: It may take up to a week of consistently running cycles to get your Flask to achieve a steady flow of bubbles. If more than a week has passed and your bottle is still having trouble producing bubbles, please reach out to our customer service team at support@echowater.com for further assistance.

Step 1: Initial Setup & Quick Guide

1. Fill the bottle with warm, filtered water and run a cycle.
2. The lids on your flask have a unique design that’s a little different from the traditional screw or threaded lids. Instead, it features tabs inside—kind of like a pressure cooker—that “lock” into place as pressure builds up.. 
3. Secure the cap before starting a cycle (ensure the lid is securely tightened, with the logo positioned perpendicular or horizontal to the flask). You may feel some resistance in the lid; however, you must continue to twist until you hear a "click". This will ensure the lid is in position. 
4. Release pressure before removing the lid. When releasing pressure, press on the side marked with a circle—pressing the middle or opposite side will not release it properly.
   
5. When the pressure releases, you may hear anything from a faint hiss to a louder pop—both are normal! You should also see bubbles rising to the top, which confirms pressurization.
6. Discard the water, rinse the flask, and it's ready for your first hydrogen cycle!

Step 2: Accelerate Hydrogenation (if needed)

If your flask doesn’t produce enough bubbles initially, don't worry! It means it just needs a quick reset. This can happen if it hasn’t been used for a while or if it got a little dry and needs rehydration.

1. Soak the bottle in Hot Water overnight.
2. Run a cleaning cycle, discard the cleaning water, and refill with filtered water.

Your Echo Flask™ will then be fully primed for peak performance!

It may take up to a week of regular use to fully rehydrate the electrode and achieve a consistent bubble flow. If you see progress, this means your Flask is working properly

1. Removing the Lid

The lid on your new product may feel a bit snug initially, but this is normal and will ease over time as it breaks in.

• To remove the lid, please ensure you have released any pressure in the flask. When releasing pressure, press on the side marked with a circle—pressing the middle or opposite side will not release it properly. In the beginning, your flask may be a bit harder to open; however, it will become easier with use.
  
• When the pressure releases, you may hear anything from a faint hiss to a louder pop—both are normal! You should also see bubbles rising to the top, which confirms pressurization.
• Gently push down and twist it counter-clockwise to unlock.
• As a precaution, avoid placing your fingers under the lid while twisting, as the bottom edge may feel pointed. Instead, grip the sides of the lid securely while twisting.

The lid will become more comfortable to handle, ensuring a smooth and enjoyable experience!

2. Fill the Flask

• For optimal performance, use filtered, distilled, or reverse osmosis water. Avoid tap water, as its high mineral content can lead to buildup and reduced performance.
• Fill to the top of the bottle's shoulder (no liquid should be visible in the spout).
  

3. Seal the Lid

• Apply downward pressure while twisting the lid to close it to the right.
• Ensure the logo is parallel or perpendicular to the flask for a proper seal. You may feel some resistance in the lid; however, you must continue to twist until you hear a "click". This will ensure the lid is in position. 
  Note: If the lid isn’t aligned correctly, pressure will not build during the cycle and will not release properly.

4. Activate Hydrogen Generation

• Wake the Touch Screen: Tap the screen to activate the display.
• Unlock the Interface: Swipe up on the screen.
• Start Hydrogenation: Press the play button to initiate a 10-minute cycle (default setting).
  
• Tap the "+ or—" options on the timer to lengthen or shorten the cycle duration. Each tap increases or decreases the duration by 1 minute.
• Auto-Lock Feature: If no adjustments are made, the screen locks automatically after 3 seconds. Swipe up to unlock.

5. Cycle Completion

• At the end of the cycle, the flask will display a “Ready” message.
• Note: If you would like alerts on your device, you can adjust the sound settings in the Echo Water app.

6. Stopping a Cycle Early

• Press and hold the stop button for 3 seconds to terminate the cycle prematurely.
  Note: Cycles stopped before 2 minutes will not count toward drinking goals in the Echo Water app.
• To reduce cycle time, tap the time display, and it will decrease it by a minute.

7. Release Pressure Before Drinking

• Press the small indent (circle) on the lid to release pressure. If you press on the opposite side or middle of the lid, the pressure will not release. Once pressed, you will hear anywhere from a faint hiss to a louder "pop"- both are normal. 
  
• Twist the lid open to access your hydrogenated water. Enjoy!
  NOTE: Your flask may be a bit harder to open in the beginning; however, it will become easier with use.

Hydrogen Water Usage and Benefits

Therapeutic Levels: The Echo Flask™ generates up to 6 PPM (parts per million) of hydrogen during a 10-minute cycle (default) and up to 8 PPM (parts per million) of hydrogen during a 20-minute cycle (two 10-minute cycles run consecutively), ensuring therapeutic levels of hydrogen-rich water.  

 

Optimal Intake:

• Aim for 3-6 bottles daily to experience potential health benefits.
• Drink hydrogen water 30 minutes before or after meals for best absorption.

Exclusivity Not Required

• Hydrogen water can be your exclusive water source, but it does not need to make up your entire daily intake.
• Your body expels excess hydrogen naturally.

Tracking Your Progress

• Consistency is Key: Benefits may take several months of regular use to appear fully.
• Journal Your Changes: Track improvements in areas like sleep quality, joint health, digestion, energy, and mental clarity.
• Individual Results Vary: Effects depend on your unique health and chemical makeup, and benefits may develop partially or fully over time.

Getting Started With Hydrogen Water

Start Low and Build Gradually

• Begin with 4-6 ounces daily if you're new to hydrogen water.
• Mild detox effects such as headaches, sleeplessness, or bloating may occur but typically subside as your body adjusts.
• Gradually increase intake as your body becomes accustomed to hydrogen water.

Stay Consistent

• Incorporate hydrogen water into your daily routine.
• Drink at regular intervals, either 30 minutes before meals or 30 minutes after meals.
• Consistency is key to achieving optimal results.

Consult a Healthcare Professional

• If you have health concerns or medical conditions, consult your doctor for personalized advice before starting hydrogen water.
• For more information, visit our guide: Everything You Need to Know About Hydrogen Water.

Hydrogen Water Consumption and Storage

Immediate Use

• Consume hydrogen water immediately after hydrogenation for the highest hydrogen concentration and maximum benefits.
• Retains therapeutic hydrogen levels for up to 24 hours, but concentration gradually decreases over time.
• Do not microwave, refrigerate, or freeze the Echo Flask™.

Open Glass

• Retains hydrogen for up to 2 hours in an open, unsealed container.
• Tip: Immediate consumption ensures the highest hydrogen concentration.

Water Bottle

• A sealed, insulated water bottle retains hydrogen for 2–5 hours, even when periodically opened.
• The highest concentration occurs within the first 2 hours.

Sealed Container

• A full, sealed, airtight container slows hydrogen loss, decreasing by approximately 0.1 ppm per day.
• Hydrogen water stored this way remains effective for up to 2 weeks, depending on the starting ppm.

Note: Avoid storing hydrogen water in copper containers. Copper reacts with hydrogen, reducing its effectiveness and benefits.

Guidelines for Using Hydrogen Water with Cold Water, Heat, and Additives

Cold Water

• Adding ice to hydrogen water is perfectly fine and does not significantly impact its hydrogen content.
• Temperature Effects: Cool water helps keep hydrogen dissolved longer, but excessive stirring or pouring may cause hydrogen to escape.
• Do not microwave, refrigerate, or freeze the Echo Flask™.

Heating Water

• Use warmed, non-boiling, filtered water in your Echo Flask™, ensuring it is plain water without additives.
• For Hot Beverages (e.g., coffee or tea):
  1. Hydrogenate the water first.
  2. Heat the water after hydrogenation.
  3. Mix or steep in a separate container.
• Heat Effects: Heating may slightly reduce hydrogen levels, but the therapeutic benefits remain.

Additives

• Never directly add supplements, minerals, or flavorings to the Echo Flask™. It is designed to work exclusively with standard (non-carbonated) water.
• Mix in Another Container: Hydrogenate the water and transfer it to another container before adding flavors, minerals, or supplements.
• Tip: Adding supplements may displace some hydrogen molecules, so a slight increase in water intake may be needed for the same benefits.
