Before making a decision on the type of water filter is best for your appliance and your home's needs, purchase a home water test kit to determine what impurities are present. Then, you can find a filter that will remove those impurities specifically. For taste, odor and particle impurities, a basic activated-charcoal filter is sufficient. For certain water-borne parasites, heavy metals such as lead and other contaminants, you may need a reverse-osmosis filtration system.
