You've got two options if you need a model number 8171413 refrigerator water filter. The first is produced by AquaFresh and the other is a factory original product from Whirlpool. Both of these fridge filters are used as replacement filters in Amana and Kenmore refrigerators. While the AquaFresh filter is not a factory original, it is produced by a leading company to the exact same standards as the original filter. The Whirlpool refrigerator filter is a factory original product that is exactly the same as the filter currently found in your refrigerator. It is an OEM part and has been tested by NSF International to ensure that it provides the cleanest drinking water and ice possible.
Both of these refrigerator water filters have a replacement schedule of 6 months. If the refrigerator water filter is not changed at the appropriate time, then the filter will not be able to work properly. The water filters start to get dirty from removing the contaminants from your drinking water. Once this occurs, the filter will stop removing the particles and chemicals from the water, which will mean you're drinking contaminated water.
