Product FAQs
The KENT Sterling Star is an under-the-counterRO water purifier using the multi purification process of RO+UV+UF+Alkaline+Copper+TDS Control with Kent's Mineral RO™ technology. Unlike standard under-counter purifiers, the Sterling Star adds Alkaline and Copper stages, producing water with a pH of 8–9.5 and active copper enrichment. Its hidden installation keeps countertops completely clear, making it ideal for premium modular kitchens.
The KENT Sterling Star's Alkaline filter raises purified water's pH to 8–9.5. Regular consumption of this mildly alkaline water helps neutralize body acidity, supports better cellular hydration, reduces acid reflux, boosts immunity, and may have antioxidant benefits. For health-conscious households, the alkaline output of the Sterling Star makes it a significant upgrade from standard under-counter RO purifiers.
The KENT Sterling Star's active Copper filter adds trace copper ions to purified water in a safe, controlled amount within permissible health limits. Copper-enriched water delivers natural antimicrobial benefits, supports digestive health, improves thyroid function, and boosts immunity — replicating the Ayurvedic practice of copper vessel water storage in a modern, hygienic under-counter purifier.
The KENT Sterling Star uses six stages: RO removes dissolved heavy metals, salts, arsenic, fluoride, and pesticides; UV kills bacteria and viruses; UF removes fine particles and cysts; Alkaline raises pH to 8–9.5; Copper adds beneficial trace copper; and TDS Control retains essential minerals via Mineral RO™ technology. This comprehensive process delivers water that is pure, mineral-rich, alkaline, and copper-enriched.
The KENT Sterling Star uses a hydrostatic storage tank that maintains internal pressure for consistent water delivery through the kitchen faucet at normal tap speed — unlike gravity-fed open tanks. This pressurized storage minimizes water's exposure to air and contamination, while providing fast and convenient water dispensing integrated seamlessly with your kitchen faucet.
Yes, the KENT Sterling Star is specifically designed for under-sink installation in modular kitchens. The compact unit fits inside a standard under-sink cabinet, and only a sleek faucet is visible on the counter. This design maintains the clean, uncluttered aesthetic of modern modular kitchens while providing premium purification with Alkaline and Copper enrichment.
Both the KENT Sterling Star and KENT Sterling IoT are under-counter purifiers with Alkaline, Copper, and Mineral RO™ features. The KENT Sterling IoT adds full IoT smart monitoring — digital display, KENT Service app connectivity, automatic service call registration, and real-time water quality tracking. The Sterling Star is for buyers who want the health benefits of alkaline and copper water in an under-counter design without smart features.
Yes, the KENT Sterling Star effectively purifies borewell water, brackish water, tap water, and municipal supply. The RO membrane removes high TDS, dissolved heavy metals, arsenic, fluoride, nitrates, and pesticides. The TDS Controller ensures optimal mineral retention in the purified alkaline copper-enriched output.
The KENT Sterling Star purifies water at 20 litres per hour with its 6L hydrostatic Storage tank; it provides a consistent, pressurized supply of purified alkaline water for a family of 4–6 members for daily drinking and cooking needs. The auto-refill mechanism keeps the tank at optimal pressure.
The KENT Sterling Star is available at kent.co.in/products/kent-sterling-star, through KENT's authorized dealer network, and on major e-commerce platforms.
