The LG WW131NF water purifier is a testament to the principle that essential safety should never be compromised. Positioned as a highly accessible RO purifier, its standout feature is the Stainless Steel Tank, a premium component that ensures the hygienic storage of water. This model provides effective multi-stage RO filtration to remove dissolved impurities, making it ideal for areas with high TDS water. By focusing on core purification and superior tank hygiene, the WW131NF offers incredible value and peace of mind, making it a smart, budget-friendly investment for any family.
Purity and Hygiene at Its Core
Hygienic Stainless Steel Tank: The Core of Purity
The single most important feature of the WW131NF is its 304-grade stainless steel tank. Unlike plastic tanks that can degrade and harbor bacteria, this steel tank guarantees that water remains as pure as it was when filtered. It inhibits E.coli growth by 94.4%, prevents chemical leaching, and maintains freshness, offering durability backed by a 10-year warranty.
Dependable Multi-Stage RO Filtration
This purifier employs a multi-stage process centered around a high-quality Reverse Osmosis (RO) membrane. It effectively removes dissolved contaminants like salts and heavy metals, along with physical impurities, bacteria, and viruses. The Post Carbon filter further enhances the taste, ensuring the final output is clean and safe.
Flexible and Practical Design
The WW131NF offers versatile wall mount or countertop installation, allowing it to fit into any kitchen layout. Its smart display provides essential alerts, including a filter change indicator, ensuring you never have to guess about maintenance, and a tank full indicator prevents overflow.
