LG Refrigerator Water Filter Replacement: Advice & Tips

Let’s talk about the replacement water filter for your LG refrigerator.

You basically have two choices when it comes to a water filter replacement: the manufacturer’s (LG’s) own filters. Or a third-party filter. 

As you can imagine, LG recommend you use their own factory filters . . . which can be rather pricey. LG warns that third-party filters:

  • Can cause damage not covered under the LG warranty.
  • Are not guaranteed to properly filter water.
  • May not fit correctly.

So when we looked at third-party filters, we researched their overall quality and performance.

When it comes to water filters, there are a series of quality standards that apply—these are set by the NSF International, which is part of the American National Standards Institute (ANSI). 

Here is what you’d see on the filter:

NS42: These filters remove chlorine, taste and odors. This standard also requires the filter itself not leach contaminants into your water.

NS53: This filters out a series of other contaminants like asbestos.

NSF372: This filters out lead.

You’ll see these standards listed on the filters recommended in this article.

Here are the filters we’d recommend as replacement water filters for a LG refrigerator:
