How often should I replace my refrigerator water filter?

Most manufacturers recommend replacing your water filter every 6 months or when your filter indicator light turns on, whichever comes first. Regular replacement ensures optimal water quality and ice purity.

Are NSF certifications important?

Yes. NSF42 covers aesthetic concerns like taste and odor, NSF53 addresses health-related contaminants, and NSF401 ensures lead reduction. These certifications guarantee your filter meets rigorous standards for water safety.

Can I use this filter in refrigerators other than LG?

No, this filter is specifically designed for LG refrigerators. Using an incompatible filter may result in poor filtration or damage to your refrigerator's water system. Always verify part number compatibility.
