RENTAL
NOT an ionizer · rental purifier
Cuckoo is another major Korean rental purifier brand with strong SG presence (after Coway, the second-biggest rental player). Same category note as Coway: this is RO/UF filtration, not alkaline ionization. Output pH ~7.6, negligible H₂. If you want an ionizer, look at the ionizer-specialist brands; if you want a rental dispenser, Cuckoo is a serious contender.
Second-biggest SG rental purifier brand · 5-year service · NOT an alkaline ionizer.
