Final Verdict: AO Smith Z9 Pro RO Water Purifier (Ambient & Instant Hot)
Why choose AO Smith?
The AO Smith Z5 Pro offers copper-fortified alkaline water across all major Indian water sources, but with only 162 reviews and just 1 unit left in stock at last check, we'd point most buyers toward the better-proven Native M1 (7,161 reviews, similar price) or KENT Grand RO instead, unless you specifically want this exact AO Smith model.
Why choose AO Smith?
If you specifically want instant hot water for tea, coffee, or baby formula alongside RO purification, the AO Smith Z9 Pro is the only genuine option in our lineup — nothing else here dispenses hot water. If you just want the best RO purifier and can boil water separately, the Native M2 Pro or KENT Grand RO get you there for meaningfully less.
