Frequently Asked Questions

Which LG refrigerator models is the Tier1 5231JA2006B (LT600P) replacement filter compatible with?

The Tier1 LT600P replacement filter is engineered to fit a wide range of LG and Kenmore side-by-side and bottom-freezer refrigerators that use the 5231JA2006B, LT600P, 5231JA2006A, 5231JA2006B-S, 5231JA2006E, and 5231JA2006F cartridges. It is also compatible with Kenmore models using filter numbers 46-9990, 9990, and 469990. Always verify your original filter part number before ordering to ensure a proper fit inside your LG fridge's filter housing.

What is the micron rating and filtration life of the Tier1 LT600P refrigerator water filter?

The Tier1 5231JA2006B (LT600P) features a 5-micron carbon block filtration media designed to capture fine particulates while maintaining steady water flow. Each cartridge delivers a filtration capacity of up to 300 gallons or approximately 6 months of use, whichever comes first. Households with heavy water consumption or poor source water quality may need to replace the filter sooner to maintain optimal taste and flow rate.

Is the Tier1 LT600P filter NSF/ANSI certified, and what contaminants does it reduce?

Yes, the Tier1 5231JA2006B LT600P replacement is tested and certified to NSF/ANSI Standard 42 for the reduction of chlorine taste and odor. Its premium coconut shell activated carbon block media effectively reduces chlorine, bad tastes, unpleasant odors, sediment, rust particles, and turbidity from your drinking water and ice — giving you cleaner, fresher water directly from your LG refrigerator dispenser.

How do I install the Tier1 LT600P replacement filter in my LG refrigerator?

Installation of the Tier1 LT600P is tool-free and takes only a minute. Locate the filter housing (typically in the upper-right corner of the fresh food compartment on LG models), turn the old filter counterclockwise a quarter turn, and pull it out. Remove the protective cap from the new Tier1 LT600P, insert it into the housing, and rotate clockwise until it locks. Flush 2–3 gallons of water through the dispenser to clear carbon fines and air before using the water or ice.

How do I reset the filter indicator light after installing the Tier1 LT600P?

After installing your new Tier1 5231JA2006B LT600P filter, reset the indicator light by pressing and holding the "Filter" or "Water Filter" button on your LG refrigerator's control panel for about 3–5 seconds until the light changes from red to green (or turns off). This resets the 6-month replacement timer so your fridge accurately tracks when the next Tier1 LT600P replacement is due.
