H2gO Purifier
A USB-C rechargeable electrolysis device that turns ordinary table salt and water into a powerful disinfectant on demand — no chemicals to buy, nothing that expires on the shelf, ready whenever you need it.
Clean Water, On Demand, Anywhere.
H2gO turns common table salt and water into a powerful disinfectant solution — no chemical tablets to stockpile, no shelf life to track, no resupply run when the shelves are empty. Just salt, water, and a charge.
Two Models. One Mission.
Choose the H2gO built for how you prep, travel, and camp.
Also available: the H2gO Bandana (camo or blue, printed with reference instructions), a 25-count box of Test Strips to verify disinfectant concentration, a Brine Bottle for mixing salt brine, and the STREAM Disinfectant Generator for larger-scale needs.
Water Purification, Reimagined.
Everything you need to disinfect water in the field — none of the chemical resupply headaches.
Electrolysis On Demand
A small USB-C rechargeable device uses electrolysis to convert a simple salt brine into a powerful disinfectant solution — chemistry you make yourself, whenever you need it.
Never Expires
Unlike purification tablets that lose potency on a shelf, H2gO has no expiration date — as long as you have salt, water, and a charge, it works.
No Chemicals to Buy or Store
Skip the bulky chemical jugs and bleach bottles. All H2gO needs is common table salt — cheap, shelf-stable, and easy to carry in bulk.
Reusable Indefinitely
This isn't a single-use tablet. Recharge it, refill the brine, and it's ready to disinfect the next batch — over and over, for years.
Backup or Complement to Filters
Pairs well with filter-based systems like a Grayl bottle — filtration removes particulates, H2gO adds a chemical disinfection layer for extra confidence.
Compact & Field-Ready
Small enough for a go-bag or glovebox, with test strips and a brine bottle available so you can verify concentration and mix on the go.
"Ran on H2gO for seven days when an ice storm knocked out our well pump — it just worked."
Built for the Days When the Tap Doesn't Work
H2gO owners aren't just campers testing gear — they're families who've relied on it during actual multi-day power and water outages, and preppers and bushcrafters who value a solution that never expires and needs no chemical resupply.
- Reported use during a 7-day ice storm outage with well pump failure
- Favored by preppers for its no-expiration, no-resupply design
- Used by campers and hikers alongside filter systems like Grayl

Salt. Water. Charge. Done.
H2gO is built to be simple enough to use under pressure — no manuals, no measuring chemicals.
Mix the Brine
Dissolve a small amount of common table salt in water using the Brine Bottle to create the starting solution.
Run the Device
The USB-C rechargeable H2gO uses electrolysis to convert the brine into a powerful disinfectant solution in minutes.
Disinfect & Confirm
Add the solution to your water and use a Test Strip to verify concentration — safe, repeatable, and ready whenever you are.
Water Security Shouldn't Depend on a Shelf Life.
Most water purification methods run out — chemical tablets expire, filters clog, cartridges need replacing. H2gO runs on salt and a charge, so your water disinfection plan doesn't have an expiration date either.
Why We Recommend H2gO Purifier
At Guard Dawg Solutions, we vet every affiliate partner against one simple standard: would we recommend this to our own family for real-world use? H2gO passes that test — and it's not new to us.
You've already seen this device in our 72-Hour Go-Bag breakdown, listed as the H2gO GLOBAL Survival Water Purifier USB-C on our Amazon Storefront gear list, long before H2gO became an affiliate partner. This partnership grew out of a product we already trusted, not the other way around.
Water is the resource that runs out fastest in any emergency. A device that makes disinfectant from salt and a charge — with no chemicals to buy or expiration dates to track — belongs in every preparedness kit we build.
