⚠ How we work — read this first
We're not running independent lab tests yet (the Q3 2026 roadmap is public at lab.html). Until then, every brand page shows the spec data exactly as published by that brand, with the source URL linked so you can verify in 30 seconds. Prime Water is our sister brand — we disclose that everywhere. Full methodology →
🏆 The 2026 Singapore Showdown

Methodology: 21 awards across alkaline ionizers + adjacent categories. Each award based on manufacturer-claimed specs sourced from each brand's public website (link on every brand page). Independent lab verification rolling out Q3 2026 — see lab.html. Prime Water won 1 of 21 categories outright (Best published certs), plus the SG-distributed H₂ award; the other 19 went to competitors. Where Prime Water won, the card is teal-bordered.
Each "Best for X" page is a competition between brands on one specific criterion. We don't always pick our own brand.
There are 36 water-machine brands selling in Singapore. Every one has a salesperson promising "medical-grade" or "the only certified" or "lowest price." Some are run through multi-level distribution networks where the unit price funds an upline-commission chain. Most "review" sites in this niche are owned by one of the brands — including this one.
The difference: we disclose ownership at the top of every page, take zero affiliate commissions, and link to every brand's official site so you can verify our numbers in 30 seconds. Our verdicts are open to review. Methodology + how-we-source-data on the methodology page.

The short answer is yes — it meets every WHO standard. The longer answer: what's in it, what isn't, why people still filter.
Buying guideFive tiers of upgrade — from a $30 jug to a $6,500 ionizer. Ranked by cost-per-litre over 5 years.
Buying guideThe 7 questions to ask any salesperson. If they dodge any of them, walk.
CompareSide-by-side tables. Plate count, pH, ORP, warranty, install, filter cost.
PUB water is some of the safest in the world. The marketing of every ionizer brand depends on you not knowing the difference between "safe" and "ideal for daily drinking." Here's the unvarnished version.
7.0 – 8.5
pH at the tap (PUB 2024 report)
+300 mV
Typical ORP — slightly oxidising
0.5 ppm
Residual chlorine — within WHO limits but tastable
99.99%
WHO compliance — translation: already very safe
