A refrigerator water filter is an integral component of any home's water filtration system. This filter extracts impurities (such as chlorine, sediment, and bacteria), ensuring that the water and ice you make use of are clean and safe to drink.Like all filters, a refrigerator water filter ought to be replaced regularly to continue to operate properly. In general, it’s recommended that you replace your refrigerator water filter every six months to one year. The reason is that, over time, the filter can become clogged with impurities; consequently, it loses its effectiveness and may allow harmful contaminants to pass through. We don’t want that, do we?
