After buying my Berkey, I didn't like the taste of the water and didn't realize that you either get Flouride in your water with Berkey or Alumina from the flouride filter. I'm very happy with the ULTRA-UC from Pure Effect Filters. The water tastes great and it's so convenient to have great water on tap. Installation was a bit difficult, but mostly the process of removing our old RO unit. I highly recommend it. The water tastes great.
