iBottle+ vs HolyH2O Infinity: Why I’d Choose iBottle+

“I’d choose iBottle+ 400 mL: more water per fill, a glass vessel and A$176 less to spend.”

Sam, iBottle

I’d choose iBottle+ 400 mL over HolyH2O Infinity. You get a larger glass bottle for A$199 with free Australian shipping, compared with A$375 for Infinity. That A$176 difference is hard to justify when the report cited for Infinity names a different bottle and its material descriptions don’t agree.

I looked beyond the headline ppm claims. Here’s what I found in the original report, the product manual and public buyer reviews.

Why iBottle+ gets my vote

For me, the glass vessel, extra 190 mL per fill and lower price make iBottle+ 400 mL the better everyday buy. Prices and sources checked 1 October 2026.

What does Infinity’s H2 Analytics report actually test?

The report is publicly available. The important question is which bottle it covers. HolyH2O cites report H2A-240122-1. The original PDF hosted by H2HUBB names Spirit H2’s SH500 Essence V2, with an approximately 225 mL polycarbonate vessel. It does not name HolyH2O Infinity or Classic.

HolyH2O says this is the SPE/PEM platform used in Infinity. That explanation matters, but I’d still want the connection to the exact bottle being sold documented. A shared technology label alone doesn’t establish identical performance.

There’s also a cycle mismatch. HolyH2O’s guide gives 2.73 mg/L after three minutes. The original report records that mean after five minutes, and 6.23 mg/L after ten. Testing used static headspace gas chromatography, distilled water at 24.5°C ± 1.5°C, a prepared membrane and USB power connected.

These are useful results for the tested Spirit bottle. They don’t, by themselves, settle the performance of every Infinity or Classic sold today.

The glass and capacity descriptions need a closer look

HolyH2O’s best-bottle guide describes its three bottles as borosilicate glass. Its product FAQ instead identifies Infinity as Tritan, while the linked Infinity manual lists food-grade polycarbonate and 210 mL capacity. Those are different descriptions, and neither polymer is borosilicate glass.

If you’re buying specifically for glass, that distinction is worth checking before checkout. With iBottle+ 400 mL, the drinking vessel is borosilicate glass. You also get nearly twice the water per fill compared with the manual’s 210 mL Infinity capacity.

The buyer complaints I’d read before ordering

On ProductReview, the Hydronizer listing showed 4.4/5 from 126 reviews; HolyH2O’s separate brand listing showed 3.4/5 from seven. Most Hydronizer ratings were positive, but the negative experiences below deserve a read. These listings cover multiple models and products.

Hadrian Dundas-Taylor wrote, “it lasted about two weeks”. His February 2026 review describes a bottle failure and unanswered refund requests, without identifying Infinity. HolyH2O replied that it could not locate his order or unresolved request and asked for purchase details.

JHT wrote, “Very disappointed for $120 drink bottle”. The review describes charging problems, a replacement base and an unsuccessful home hydrogen test. The model is unspecified; the home test is a buyer’s account, not an independent laboratory finding.

On Trustpilot, Victor Joyce wrote, “i had dozens of emails just totally ignored”. His April 2026 complaint concerns delayed orders and a disputed refund involving two Hydronizers and a benchtop unit. The same case appears on ProductReview, where HolyH2O said support requests were handled and rejected allegations of dishonesty. This is one case across two sites, not two separate customers.

I’d read the full exchanges before relying on a guarantee. The Trustpilot brand profile had only one review when checked, so it is a very small sample.

What the iBottle+ report shows

iBottle+ isn’t limited to a 4,000 ppb headline. Our published 400 mL report, STECH-IBP-0225, records mean concentrations of 4,050 ppb after one five minute cycle and 6,200 ppb after two consecutive cycles. It used distilled water at 20°C and H₂Blue reagent titration.

You can read the actual model, cycle times and method before buying. Our testing overview also explains our H2HUBB and H2 Analytics report information. The published 400 mL results above belong to that model; the different laboratory methods aren’t a head-to-head test.

My winner: iBottle+ 400 mL

iBottle+ is my best overall choice in this comparison. A$199 buys the larger glass bottle, SPE/PEM generation, an IP67 water-resistance rating and published model-specific results. I don’t see a convincing reason to spend another A$176 on Infinity given the questions above.

Choose iBottle+ 400 mL for glass and more water per fill. Prefer a smaller bottle? The 230 mL iBottle+ is also A$199. Our best overall and best value guide explains the other iBottle options.
