NOT an ionizer · rental purifier
Coway is Korea's biggest rental water-purifier brand and has a massive Singapore presence — you've probably seen them in MRT ads or mall booths. But critical category framing: Coway makes RO/UF filtered water purifiers, not multi-plate alkaline ionizers. The output is pH ~7.5, near-zero hydrogen. If you're comparing Coway against a 9-plate ionizer, these are different products.
Biggest SG rental purifier brand · S$49/mo with 5y service · NOT an alkaline ionizer.
