LG refrigerators equipped with Linear Compressor technology are known for their energy efficiency, quiet operation, and advanced cooling performance. Many of these models also include a built-in water filtration system, providing clean and fresh drinking water directly from the dispenser. However, users often struggle to locate or replace the water filter, leading to confusion or improper maintenance.
Understanding the LG Linear Compressor Refrigerator Water Filter System
Before locating the filter, it’s important to understand how the filtration system works in an LG refrigerator:
Filtration Process: The water filter removes impurities such as chlorine, sediment, and harmful contaminants, ensuring clean and safe drinking water.
Filter Types: LG uses different filter models (e.g., LT1000P, LT700P, ADQ36006101) depending on the refrigerator series.
Filter Lifespan: Typically, LG recommends replacing the water filter every 6 months or after filtering 200 gallons of water (whichever comes first).
