These filters are meant to replace those in LG or Kenmore refrigerators and are compatible to the discontinued fridge filters for these brands. They come with pre-lubricated O rings designed to replace the separate silicone that came with the fridges, making it an easier job to replace these filters. Replacing them takes just a few minutes, and once you have placed a new date sticker on the filter, you can just snap it into place. Change the filter at least once every six months, or when you notice a strange odor or taste coming from your water.

These 5231JA2002A filters have a peak operating temperature range of 33 to 100 degrees, with a pressure of 20 to 125 pounds per square inch. While the WaterSentinel filter has a 300 gallon capacity, the AquaFresh and LG filters have a 500 gallon capacity. Each of the filters has a standard rate of flow of 0.5 gallons per minute. You should be able to get several months of pure, clean water from each filter, and with the handy three-pack, you won't have to restock your filter supply for well over a year.
