Product review (3 stars): Reduced fluoride by 50%.
I purchased this product directly from the Aquacera company. They were helpful and kind. My husband had no problem quickly attaching it to the water line of our refrigerator. I had water samples done of the filtered and unfiltered water and the fluoride was reduced by only about 50%. This was disappointing, but considering the cost and ease of installation, it is still a decent option. What would be really great is if my city stopped putting dangerous toxic chemicals in the water, effectively medicating everyone using city water. To summarize: for the money and the trouble, it's still worth using until something better comes along.
