The Aqua S is the value play in hot-water purifiers. AO Smith's Z9 is the better machine, but it is ₹34,000 and the Aqua S delivers the feature that actually changes your daily routine — instant hot water for tea, coffee and baby formula — for ₹21,500, in a better-looking body, with a three-year membrane warranty attached.
