Very satisfied with results, using Detroit area tap water.
Been using the Royal Berkey for one year. The pair of PF2 fluoride filters only lasted 11 months. Cleaning (back-flushing) did not help.
The upper chamber (black) filters are supposed to last three years or so. They still filter out the red food coloring, and I only cleaned the pair once. (Wife and I filter about 15 gallons per week).
A friend of mine has well water, but Berkey clogs up pretty quickly because of minerals.
Takes all of the chlorine taste/odor from my tap water.
