Updated March 18, 2026

Kent Supreme Plus Alkaline+Copper RO Review: Under ₹15,000

The Kent Supreme Plus delivers the most comprehensive purification technology in this price segment with RO+UV+UF+Alkaline+Copper+TDS Control. Its 20 LPH purification rate is the highest in the under Rs 15,000 category, and the alkaline output reaches pH 9.5.

Decision Snapshot

Near the Rs 15,000 ceiling at Rs 13,500-14,500, the Kent Supreme Plus justifies its premium with the fastest 20 LPH rate, alkaline water at pH 9.5, copper infusion, and UV LED in-tank protection. Kent's 1-year warranty plus 3-year free service provides 4 years of coverage, the longest total in our list. The 4.1-star rating from 16,264 reviews is battle-tested. Higher 60W consumption and lack of scientific consensus on alkaline benefits are the trade-offs.

Best For

Health-conscious families with 4-5 members in North India who want alkaline and copper-infused water from a brand with the widest service network in India.

Watch Outs

Budget buyers under Rs 10,000 or families who just need reliable basic RO+UV purification without premium alkaline and copper features.

Detailed Review

Editorial Take

The Kent Supreme Plus is for health-conscious families who want the most advanced purification technology available under Rs 15,000 in India. The 20 LPH purification rate is the fastest in our entire list, meaning your tank refills significantly quicker than competitors.
