KENT
KENT Grand RO Water Purifier (RO+UF+TDS Control+UV LED Tank)
The KENT Grand RO is the safe, well-proven default for Indian homes — the single most recognised name in the category, a strong 4.4★ rating from over 8,000 reviews, and India's largest RO service network behind it. If you just want a purifier that works and gets serviced quickly when it doesn't, start here.
Aquaguard (Eureka Forbes)
Aquaguard Delight Aquasaver RO+UV+UF+MC Water Purifier
The Aquaguard Delight Aquasaver trades a slightly softer 4.2★ rating for an enormous, battle-tested 9,652-review sample and Eureka Forbes' decades of Indian service infrastructure. If brand longevity and service network maturity matter more to you than squeezing out the last 0.5★ of rating, this is a safe, well-proven choice.
Livpure
Livpure GLO PRO++ RO+UV+UF Water Purifier (7L)
Livpure was a genuine gap in this catalog — a major Indian RO brand missing entirely despite having, on the numbers, the single largest and most current review base of any water purifier tracked here. The GLO PRO++ backs that up with a straightforward, competitively priced RO+UV+UF purifier. It doesn't have the mineral-enhancement extras of the Pureplus or Native lineup, but the sheer weight of proof behind it is hard to ignore.
