Installation Requirements
- The Echo H2 Flow requires pre-filtration from an existing whole-house filtration system or reverse osmosis (RO) system.
- A secondary faucet is required for under-counter installation of the Echo Flow Hydrogen Water Machine, allowing convenient and dedicated access to hydrogen-enriched water.
- Countertop Hole: A 15/16-inch to 1-inch hole is needed for installation. Many sinks already have a pre-drilled hole for soap dispensers or other accessories. If not, a countertop professional can drill one if needed.
- Electrical Outlet: The Echo Flow requires a nearby electrical outlet with a constant power supply.

- Made with BPA-free materials
- No added preservatives, additives, or artificial flavors
- Zero calories
- Uses technology that dissolves hydrogen gas into water
- Provides clean, great-tasting water
- Maintains the natural pH of the water

What is Hydrogen-Enriched Water?
Hydrogen-enriched water is regular drinking water that has been infused with dissolved molecular hydrogen gas (H₂). Echo Water® Machines are designed to produce this type of water without altering its acidity, allowing for clean, great-tasting hydration.

How Hydrogen Water Works
Many people incorporate hydrogen-enriched water into their daily routines. Echo Water® Machines dissolve molecular hydrogen directly into the water, providing an easy way to enjoy hydrogen-enriched hydration as part of everyday drinking habits.
Installation Requirements
Pre-Filtration Required: Must be paired with a reverse osmosis or whole-house filtration system.
Faucet Installation: A secondary faucet is required for under-counter setups. If your sink doesn’t have an extra hole, a professional can drill one.
Power Supply: Requires access to an electrical outlet (often shares power with garbage disposals).

Echo RO/Flow Faucet
Easily dispense hydrogen-enriched water with the Echo RO/Flow Faucet, designed for seamless integration with the Echo Flow. This sleek, secondary faucet allows for under-counter installation while delivering hydrogen-enriched water produced by your Echo Flow system.
