Why should I change my refrigerator water filter?

Your refrigerator water filter becomes less efficient over time, as it traps more and more impurities. As the water filter fills with impurities, you might notice that water flow is slowing. Changing your water filter ensures that you get filtered water that tastes and smells good.

How often should I change my refrigerator water filter?

Refrigerator manufacturers recommend installing a new water filter every 6 months. If you notice water flow slowing, change it sooner.

Can I use my refrigerator without the water filter?

Almost all refrigerator water systems will work without the water filter. With the water filter removed, unfiltered water flows directly to the ice maker and water dispenser. Check your owner’s manual for instructions on using your refrigerator without the water filter.

We don’t recommend using your refrigerator without the water filter unless your home uses a whole-house water filter.

What is NSF certification?

NSF International tests and certifies thousands of products—including refrigerator water filters—to verify they meet public health and safety standards. Water filters that meet NSF standards bear the NSF certification mark.

LG refrigerator water filters are certified by the NSF to remove chlorine taste and odor (NSF standard 42). Many LG water filters also can remove lead and cysts (NSF standard 53), and some have passed additional NSF certification tests and are certified to remove volatile organic compounds, pharmaceuticals and some pesticides (NSF standard 401). Learn more about NSF certification here.

To ensure your water filter can trap all the impurities and contaminants it’s been proven to remove, replace your refrigerator water filter every 6 months. We can send you your LG water filter replacement automatically (and with free shipping), so you don’t have to remember to reorder.
