A refrigerator water filter reduces water impurities, including lead and chlorine, to give great-tasting and great-smelling water. In addition, a refrigerator water filter protects your refrigerator and prevents water pressure decrease from the dispenser. Furthermore, drinking filtered water from your refrigerator saves you money compared to drinking bottled water, which also contributes to plastic pollution.
