Which type of filter is best?
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.
Do water filters remove desirable elements, like fluoride?
The level of filtration varies by filter. Charcoal filters do not remove fluoride but may not sufficiently remove undesirable contaminants. Reverse-osmosis filters remove nearly all impurities, including fluoride.
Do I need to filter my city water?
By law, municipal/city water must meet strict guidelines to be considered safe (potable). Contact your local municipality to learn about these guidelines. Many people choose to use a water filter with their home water supply for taste and odor-improvement purposes.
Do water filters remove chlorine?
Yes. Activated-charcoal and reverse-osmosis filters remove chlorine from water.
