If you're not sure which filter your LG refrigerator takes, check the label on your current filter or use our filter finder at discountfilters.com.

NSF certification — what it means and why it matters

Our ClearChoice and AIRx replacement filters for these LG models are independently certified to two NSF/ANSI standards:

NSF/ANSI 42 — Aesthetic effects
Covers the reduction of chlorine, taste, and odor. This is what makes your water taste and smell cleaner.

NSF/ANSI 53 — Health effects
Covers the reduction of health-related contaminants including lead, cysts, and certain volatile organic compounds (VOCs).

These are the same two certifications carried by the original LG OEM filters. The certification is independent meaning a third-party organization, not the manufacturer, verified the performance claims.

Frequently asked questions

Is your replacement filter as good as the LG original?
On the certifications that matter, yes. Our ClearChoice replacements are independently certified to NSF 42 and NSF 53, the same standards as the LG OEM filter. The difference is the price, not the performance. And if the filter doesn't fit your refrigerator for any reason, exchanges are free.

How do I know which LG filter I need?
The easiest way is to check the part number printed on your current filter. LG filters are typically located inside the refrigerator in the upper right corner of the interior or in the base grille at the bottom front. If you have the part number, search it directly at discountfilters.com. If you only have your refrigerator's model number, our filter finder can match it for you.
