The LG 5231JA2006A water filter reduces contaminants found in your water including dirt, chlorine, chemicals and unwanted minerals. The OEM LG replacement filter has been certified to meet NSF/ANSI Standard 42, meaning it is certified to reduce chlorine levels in your water. The aftermarket ClearChoice CLCH104 replacement filter has very similar features to the OEM, but it comes at a much lower price. It also has a 750 gallon filtering capacity, compared to the 300 gallon filtering capacity of the OEM. The lowest priced option we offer is the aftermarket ClearChoice CLCH104 replacement filter. The ClearChoice replacement has excellent filtration. The primary difference between the OEM and the aftermarket filter is the price and NSF/ANSI rating, though some non-NSF/ANSI rated filters are still constructed with NSF/ANSI rated parts. We offer fast shipping and free returns on all of our discount refrigerator water filters every day. Buy the LG 5231ja2006a filter today.
