Bought my original separate charcoal/fluoride gravity fed Berkey filter from the US a few years back and used this till it almost fell apart. Thought I was buying a Berkey in Australia, thinking that these were now available in Australia. Ended up getting the ProOne 11.3 gravity fed filter and was a little scepticle as the fluoride filter was integrated into the main filter. After 3 flushes, we still had a bitter taste in the water and after a phone call to Ken, he advised that it may require a further flush or two. We're all good now. The unit works well, water has the thumbs up from family members and the unit stand is a great improvement. Delivery was prompt and packing was secure. Overall, very happy.
