LG 8L RO+UV+Mineral Booster Water Purifier (WW156RTTB) Review: Essential Purity with Advanced Hygiene and Mineral-Enriched Water for 2025
For households demanding uncompromising water safety and hygiene, the LG 8L RO+UV+Mineral Booster Water Purifier (Model: WW156RTTB) is a standout choice for 2025. Dressed in a sleek Solid Black finish, this purifier combines LG’s trusted multi-stage filtration with a hygienic Dual Protection Stainless Steel Tank, ensuring water remains as pure as it was when filtered.
Key highlights include the health-conscious Mineral Booster, continuous in-tank sterilization with EverFresh UV Plus, and automated Digital Sterilizing Care. This review explores how the WW156RTTB delivers safe, great-tasting, and mineral-rich water, making it a reliable and stylish addition to any modern Indian kitchen.
Advanced Purification & Smart Hygiene: Ensuring Safe, Mineral-Rich Water
The core strength of the LG WW156RTTB lies in its robust multi-stage purification process. Water first passes through an external sediment filter with an anti-scalant module to remove large particles and prevent scaling. Inside, a Sedi + Carbon filter tackles finer sediment and organic compounds, followed by the crucial RO Membrane that eliminates dissolved impurities, heavy metals, and microbes. Finally, UV sterilization provides a second layer of defense, ensuring the water is free from bacteria and viruses.
Dual Protection Stainless Steel Tank
Unlike plastic tanks that can harbor germs, the stainless steel tank maintains purity and prevents the growth of bacteria and algae. It offers far greater hygiene and durability, backed by a 10-year warranty for complete peace of mind.
Mineral Booster for Health & Taste
RO purification often strips water of essential minerals. The Mineral Booster technology re-infuses the water with vital minerals like Calcium (Ca) and Magnesium (Mg). This not only makes the water healthier but also enhances its taste, making it feel more natural and refreshing.
EverFresh UV Plus & Digital Sterilizing Care
This purifier ensures stored water remains safe. The EverFresh UV Plus feature uses an in-tank UV LED to keep water sterilized around the clock. Digital Sterilizing Care automates the cleaning process, ensuring the entire system stays hygienic without manual intervention.
Smart Indicators & Enhanced Recovery
User-friendly indicators for filter change, UV status, and tank full eliminate guesswork and ensure timely maintenance. The enhanced water recovery system also makes the purification process more efficient, reducing water wastage.
