The Flouride Reduction Set is not for your entire house, only under the sink use. Flouride filters need extra saturation time; they only filter about ½ a gallon per minute (gpm), making them only suitable for under the sink use. Flouride is a dangerous chemical that is often added to city and county water. You’ll be saving your family from ingesting some serious poisons by making sure you include this set with your Water’s Edge system.
