The Water Filter is an OEM part for LG refrigerators. It is a component that ensures the purity and quality of your drinking water and ice.

Causes of a faulty water filter can include regular usage over time, expiration of its filtering capacity, or clogging due to sediment buildup. These factors can result in compromised water quality, decreased flow rate, or unpleasant taste and odor.

Symptoms of a bad water filter may include:

• Decreased water flow from the dispenser
• Water with an unusual taste or odor
• Visible discoloration or particles in the water

This OEM LG part can also be used on Kenmore/Sears appliances.
