Product review (1 stars): I just wanted better taste and clarity
There are many mixed reviews of this item. Unfortunately I have to take the side of dissatisfied.  I use a municipal water source so I am not concerned about safety.  I just wanted better taste and clarity.  I am happy with the clarity, neutral on the taste, totally unhappy with the water flow through my refrigerator water dispenser.  This filter restricts my water flow so much that I finally had to pull it out and replace it with the factory plug.  That restored my water flow to a normal level.  I cannot recommend this filter.
