Echo Water
Hydrogen-infused water on the go
Last updated on 17th September 2026
About Echo Water
The Echo Flask is a portable water bottle that produces hydrogen-infused water through electrolysis, aimed at people already following a wellness or performance routine who want an antioxidant boost added to their daily hydration. It suits anyone curious about molecular hydrogen research rather than needing a medical intervention, since the brand is explicit that no disease claims are made.
The core product is the Echo Flask itself, which runs a 10-minute cycle to reach up to 6 PPM of dissolved hydrogen or a 20-minute cycle for up to 8 PPM, a level the brand states is third-party certified. The unit works only with deionised or reverse osmosis water, generates hydrogen fresh with each cycle rather than relying on cartridges or added minerals, and is handwash only. Supplements and flavourings are not meant to go into the Flask itself, since anything added after the electrolysis stage is said to preserve the hydrogen content better.
Echo Water sells directly from its own site, distributed in the UK by TLKE Limited, and backs the Flask with a five-year pro-rated warranty that steps down from full cover in year one to partial cover by year five. An optional paid protection plan, Echo Care, covers accidental damage separately from that standard warranty.

Questions about Echo Water
How long does Echo Water delivery take?
Orders are typically sent out the next business day after being placed, though this can vary during especially busy periods. Delivery times shown at checkout are estimates that include this processing time, and the exact shipping method used may sometimes differ from what was selected.
How do I return an Echo Water order?
Customers have 60 days from receiving an item to request a return or exchange through the Return/Exchange Portal, and no product registration is required. Unless the item is faulty, the customer is responsible for paying return postage.
What does the Echo Water warranty cover?
Echo products come with a five-year pro-rated warranty, with coverage starting at 100% in year one and reducing over time, down to 25% by years four and five. The warranty does not cover accidental damage, negligence, staining, exposure to extreme temperatures or chemicals, or results from unapproved after-market testing meters.
What happens if my Echo Water order arrives damaged?
Customers should submit a shipping claim if an item never arrives, arrives damaged or defective, or the wrong product is delivered, and claims must be made within two weeks of receiving the item. Echo Water reviews submitted claims and responds within one business day.
Can EU customers cancel an Echo Water order after delivery?
Shoppers in the European Union have the right to cancel or return an order within 14 days of receipt for any reason, without needing to give a justification. The item must still be unworn or unused, with tags attached, in its original packaging, and accompanied by proof of purchase.
Alternatives to Echo Water - Health & Wellbeing market
- Osmio Duo A glass hydrogen bottle sold directly to UK buyers that adds a nasal cannula for inhaling hydrogen gas, though its dissolved hydrogen level runs well below the Flask's rated output.
- Oxydise Another UK-based electrolysis bottle pitched at recovery and performance use, for shoppers who want a British-run alternative without the app and warranty tiers.
- IonBottles A tiered US range sold on Amazon UK from a lower entry price, trading peak hydrogen concentration for a cheaper way into the category.
- ALTHY A budget generic electrolysis bottle with a PPB and timer display, bought by those wanting the basic function without paying for lab certification or a warranty scheme.
