Coral has the widest price band in this guide (S$949 → S$4,949) and one of the most aggressive marketing positions on filtration. The 0.0001 micron claim deserves verification — that's below RO-membrane pore size and into the range where the number becomes less meaningful. As a brand, they cover entry-level and premium with a real showroom. Spec-led buyers should ask Coral for independent test certificates on the headline filtration number before committing to the higher-tier units.

Pros
- Widest price band of any SG ionizer brand — S$949 entry, S$4,949 flagship

- "Money-back guarantee on spec" is offered (read terms carefully)
- Hydrogen + multi-stage filter combined in one unit on Premium models
Cons
- 0.0001 micron filtration claim is at/below RO-membrane pore size · ask for independent test certificate
- Specs sheet on website is light · ORP, real H₂ ppm rarely published per-model
- Defu Lane is industrial-area · not a casual walk-in location
- Wide lineup means more confusion · what's the actual difference between "9 H" and "9 H Plus"?
- 2-year warranty is mid-tier (Prime Water 5y, Wells 5y, Novita 5y all beat it)
