Hydrotech Hydrogen Water Bottle
$175 NZD Welcome Kit · bottle alone $169
The only bottle here whose headline number can be checked — named laboratory, report number, model, date, cycle length, full document published.
3,800 PPB at three minutes. Guangdong Quantum Testing Technology, report LH2025090001, model HB470, 1 September 2025. Three minutes is not a best-case setting quoted selectively — it is the only cycle the bottle has.
It is also the cheapest water on this page at $35.96 per 100ml, the only bottle here that sells every replacement part separately, and the only one where a warranty claim is a local email rather than an international parcel.

✓What's good (15)
- Independently lab-tested at 3,800 PPB — named laboratory, report number, model and date, published in full
- Three-minute cycle — the shortest here, and the only cycle the bottle has, so the figure is the figure
- 470ml double-walled borosilicate glass — the largest glass bottle in this comparison
- $35.96 per 100ml — the cheapest water on this page, less than a third of what the dearest bottle here costs for the same volume
- The price you see is the price you pay — nothing is pre-added to the cart at checkout
- One button — fill, press, drink. No settings, no modes, nothing to learn
- Welcome Kit includes two free gifts — a protective sleeve and cleaning brush, six dollars above the bottle alone
- Free NZ shipping on the Welcome Kit — no freight, no duty, no customs wait
- Rated 4.9 from 211 verified customer reviews, with photo reviews from real buyers
- Fast tracked shipping across New Zealand and Australia
- 30-day money-back guarantee — return it if it isn't for you
- 12-month warranty against a New Zealand company, so the Consumer Guarantees Act applies directly
- Protective sleeves in five colourways — the bottle is customisable rather than one-look-only
- Every component sold individually — glass bodies, bases, lids, seals, sleeves, brushes and cleaning tablets, all stocked in New Zealand. If something goes wrong you replace the part, not the whole unit
- Support answered by a named person, not a ticket queue — and customers say so in the reviews
−Worth knowing (2)
- One model rather than a range — bundles are available for households buying more than one
- A small New Zealand team supplying a growing NZ and Australian customer base, so bottles and sleeve colourways sell through and restock in batches

Hydrogen Health Water Bottle
$216 NZD · 550ml
The largest bottle in this comparison at 550ml, and the best-built of the overseas options — but the headline output figure comes with no cycle length and no published test.
The product page leans on hexagonally structured water, molecular coherence and Far Infrared "supercharging" — none of which are part of accepted water chemistry. Nothing on the page lets a buyer check the 5,500+ PPB claim, and there is no New Zealand entity to take a warranty claim to.

✓What's good (4)

- Over 400 published reviews
- Built-in filtration
−Against it (9)
- No independent hydrogen test published — the 5,500+ PPB figure rests entirely on the brand's own word
- No cycle length given, so the figure cannot be compared to any other bottle here
- 5,500 PPB is more than three times what water holds at atmospheric pressure — a sealed-chamber reading, not what reaches your mouth
- "Hexagonally structured water" and "molecular coherence" are not recognised concepts in water chemistry
- Far Infrared rays described as a "supercharger" that ionises and alkalises water — no accepted mechanism supports this
- The filter is claimed to produce a 0.06mA bio-electric current that structures water — an unverifiable claim on an unverifiable mechanism
- No New Zealand entity — a warranty claim crosses the Tasman, and the warranty terms are not stated anywhere on the product page
- Filter needs a vinegar soak every three months — ongoing maintenance the other bottles here don't require
- Sells shower filters, skin misters, benchtop systems and a breathing system — the bottle is one line in a wellness catalogue

Hydroh Hydrogen Water Bottle
$120 NZD · capacity not published
The lowest sticker price here, and the least you can find out about before paying it. No published capacity, no cycle length, no New Zealand entity — and a charge already sitting in the cart when you reach checkout.
The documentation itself is reasonable: two third-party reports are linked. Everything around it is harder to trust. A fault means posting the bottle to the United States at your own cost, and the site quotes three different customer counts across three places.

−Against it (9)
- No NZ or AU entity — a fault means posting the bottle to the United States at your own cost, with no local consumer-law recourse
- Capacity is not published anywhere on the product page — so the one figure that tells you whether the price is good cannot be worked out at all
- A $9 "Order Coverage" charge is pre-added to the cart — the $120 bottle reaches checkout at $129 before shipping, and you have to remove it yourself
- Three different customer counts across the same site — 3,800 in one section, 54,680 in another, and 7,031+ on the checkout banner
- No cycle length published, so the 2.5 ppm figure cannot be compared to anything
- Claims benefits for "over 150+ diseases" — a claim no consumer water bottle can support
- Claims three bottles equal "hundreds of fruits and vegetables" in antioxidant terms, without citing the trial
- Recommends drinking 3–5 bottles a day to see results — which also happens to accelerate repurchase
- Ships from the United States, so freight and any duty sit on top of the sticker price

EVOLV — H2GO
United States
EVOLV H2GO Superwater
$255 NZD · 230ml
$255 for 230ml of plastic. The dearest bottle in this comparison, the smallest capacity in this comparison, and the vessel is polycarbonate rather than glass.
The specification page is unusually detailed — Japanese SPE/PEM generator, DuPont Nafion N115 membrane, exhaust valve, battery capacity, two stated cycle lengths. Then the headline says 5.4 PPM while the specs say 5 PPM at ten minutes, and the pricing block quotes New Zealand dollars, United States dollars and a $511 "total value" in the same breath.

- 45-day money-back guarantee
−Against it (11)
- $110.87 per 100ml — three times the cost per millilitre of the bottle ranked first, and the worst value in this comparison
- 230ml is the smallest capacity here, less than a standard glass of water per charge
- The bottle is BPA-free polycarbonate — plastic, not glass, at the highest price on this page. The aluminium sleeve is an outer shell, not the vessel
- The headline says 5.4 PPM but the spec table says 5 PPM at ten minutes — the number on the buy button does not match the number in the specifications
- 5,000 PPB is more than three times what water holds at atmospheric pressure
- Ten minutes is the longest cycle in this comparison, and the headline figure depends on it — the five-minute setting delivers half
- The pricing block mixes three currencies at once — $255 NZD, "$150 USD savings" and a "$511 NZD total value" — so a buyer cannot tell what the discount actually is
- The $511 "total value" anchor is not substantiated anywhere on the page
- "11x more hydrogen" is stated with no comparator — eleven times more than what is never said
- Celebrity handles are displayed under "and thousands more follow us" — following a brand is not endorsing a product, but the layout invites the reading
- Marketing leads with a Japanese flag for the generator while the specification confirms assembly in China

Ionza — H₂ Pro Kit
New Zealand
Ionza H₂ Pro Kit
$230 NZD · 300ml
$230 for 300ml, and the "independent testing" on the page doesn't measure hydrogen at all.
Ionza's accredited July 2025 report is a food-contact safety test: heavy metals, migration, PAHs. It is genuine and it passed. What it does not do is say anything about hydrogen output — yet it sits on a page that leads with hydrogen figures, and then claims "10 ppm" at unspecified durations, six times what water can physically hold.

- Inhaler kit included
−Against it (8)
- The "independent test" measures food-contact safety, not hydrogen — heavy metals, migration and PAHs. It says nothing about the 2.5 ppm figure it sits beside
- Claims "10 ppm or 10,000 ppb" at extended durations with no duration stated — more than six times what water holds at atmospheric pressure
- That claim contradicts the same page's own careful figures of 1.8 ppm at five minutes and 2.5 ppm at ten
- ORP range is quoted two different ways on one page — −350 to −700mV in one place, −450 to −750mV in another
- $76.67 per 100ml — more than double the cost per millilitre of the bottle ranked first, for 300ml a charge
- Claims therapeutic effects on asthma, Parkinson's, Alzheimer's and lung damage from inhaler use — claims no consumer device can make in New Zealand
- No replaceable parts — a worn component means a new unit
- Primarily a water filtration company — jugs, alkalisers and whole-home systems, with the bottle as a side line

HydroGenix 6,000 PPB Bottle
$199 NZD · 250–270ml
$199 for 250ml. One glass of water, thirty dollars more than a 470ml bottle, and the brand recommends drinking it within the hour.
The 6,000 PPB headline arrives with no cycle length and no linked report — the site references third-party testing but publishes none. The range also includes a model sold on "bio resonance," which is not a recognised mechanism.

- Sells a model on "bio resonance" — not a recognised mechanism, sitting inside a range otherwise sold on technical specification
- No replaceable parts, confirmed in the brand's own FAQ — a worn component means a new bottle
- Site claims 7,000+ customers but publishes 69 reviews
- Wider catalogue includes skin care, pain relief tablets and inhaler rentals — the bottle is one product among many

Why the biggest number isn't the best number
Water holds about 1,600 PPB of dissolved hydrogen at atmospheric pressure. That is Henry's Law, not a manufacturing limit. Going higher means pressurising a sealed chamber, which is what these bottles do — and water above saturation is unstable. The excess starts escaping the moment generation stops and leaves faster once the lid is off.
So a 6,000 PPB claim describes a reading taken inside a sealed vessel. Three sips later that water is heading back toward 1,600 PPB. Published human studies mostly used 1,000 to 1,600 PPB, and above that more is not better in any way a drinker experiences.
Which is why this ranking is not a leaderboard of PPB figures. What separates these bottles is whether the number was measured, how long the bottle ran to reach it, how much water you get for the money, and who answers when something breaks.
A note on reviews
Review counts are the easiest number in this category to inflate. What is harder to fake is detail — and Hydrotech's 211 verified reviews, averaging 4.9, are unusually detailed.
Customers post their own photographs of the bottle in their kitchens and cars. They name the person who helped them. They write about the taste of the water, the weight of the glass, how the sleeve fits. Several are a year or more into owning one. A meaningful number came back to buy a second, or a third for family.
That is what a real review page reads like: specific, photographed, and written by people who clearly still have the product.

Scores are an overall assessment across these six criteria. Figures taken from each brand's published specifications and third-party reports as at August 2026. All prices shown in New Zealand dollars as displayed to a New Zealand buyer. Cost per 100ml is calculated from published price and published capacity. Overseas brands may add freight and duty at checkout. Nothing on this page is intended to diagnose, treat, cure or prevent any condition.
The verdict
Five of these six bottles ask buyers to take a number on faith. One publishes the lab, the report number, the model, the date and the cycle — and lets anyone read the document.
Hydrotech scores 4.9 out of 5, the highest here: independently measured at 3,800 PPB on the shortest cycle in this comparison, 470ml of double-walled borosilicate glass, New Zealand warranty cover, and every replacement part sold separately. At $35.96 per 100ml it is also the cheapest water on this page — and the price you see is the price you pay.
Worth knowing: the Welcome Kit is currently $175 against a $229 recommended price, with several components flagged low stock. Sleeve colourways run out and restock in batches.
