Initially this is more of a pricy upfront cost, however considering the filter life Berkey is fantastic for a countertop water treatment system, especially given the capabilities of filtering out fluoridated water. Also the fact the Berkey is metal and not plastic gives it the top spot for suggested filtration systems. As for the filter replacement, it would vary on how dirty the water is in the first place.
