Echo Flask™ Design and Materials

Here's everything you need to know about the Echo Flask™ materials, components, and features:

Bottle Materials

The Echo Flask™ is crafted using premium materials for safety, durability, and convenience.

Inside of the Echo Flask™ (Water Contact Surface):

• Material: Polyphenylsulfone (PPSU) plastic.
• Key Benefits:
  • BPA-Free: Free of BPA, BPS, and other harmful chemicals for long-term, safe use.
  • FDA-Approved: Certified by the FDA for safety.
  • Trusted Material: Commonly used in medical devices, baby bottles, and lab equipment due to its durability and chemical stability.
  • Durable: Scratch-resistant, lightweight, and temperature-resistant, capable of withstanding varying temperatures without degrading or releasing harmful substances. Please keep away from extreme heat or cold surfaces. Damage due to scratches or heat/cold exposure is not covered under warranty.
  • Safety: PPSU was chosen to ensure safety and longevity, especially under the pressure required for true hydrogen production. Unlike glass, which can shatter or even explode under high pressure, PPSU offers a durable and secure solution.
  • Non-toxic: Resists absorbing odors, stains, or colors, keeping your water pure.
  • Eco-Friendly: PPSU is recyclable and has a lower environmental impact than many other plastics.

Flask Housing (Outer Layer):

• Material: Thermoplastic urethane (TPU).
• Key Benefits:
  • Flexible Durability: TPU is both tough and flexible, making it resistant to wear and tear over time.  
  • Scratch and Abrasion Resistance: Even with regular use, the housing usually remains smooth and intact. Although the Echo Flask™ is scratch-resistant, it is not scratch-proof, and scratches are not covered under warranty.
  • Temperature Stability: Designed to handle varying temperatures without cracking or warping. Please keep away from extreme heat or cold surfaces. Damage due to heat/cold exposure is not covered under warranty.
  • Eco-Friendly: TPU is recyclable and has a lower environmental impact than many other plastics.
  • Comfortable Grip: Its soft yet sturdy texture provides a secure and comfortable grip.

Hydrogen Generator

The Echo Flask™ uses Solid Polymer Electrolysis (SPE) technology for safe, effective hydrogen generation.

Benefits of SPE Technology:

• Pure Hydrogen: Generates clean hydrogen with no harmful byproducts.
• Durability: Engineered for reliable, long-term use.
• Environmentally Friendly: Releases only oxygen into the atmosphere for a green solution.

PEM System (Proton Exchange Membrane):

• Dual-Chambered Nafion Technology enhances performance and safety.
• Key Features:
  • Oxygen Port: Safely vents oxygen during electrolysis.
  • Purity: Produces no chlorine, ozone, or hydroxyl byproducts.
  • Stable pH: Ensures neutral water pH without added acidity or alkalinity.

Battery Features

The Echo Flask™ is powered by a rechargeable 2200 mAh (7.4 Wh) lithium-ion battery.

• Rechargeable: Convenient and eco-friendly for daily use.
• High Capacity: Powers up to 7 hydrogen generation cycles on a single charge.
• Air Travel

We’re committed to providing you with a product that’s not only high-performing but also safe and built to last.
