We purchased a Royal Berkey from Scott for our office, we are thrilled to say that the water tastes amazing, we no longer have to lug big water bottles in the winter to get filled up and best of all with the Alkalizing Stones our PH level has really increased meaning everyone can live a more Alkalized Life while in the office which should help build our employee's immune systems. Really crazy thought, we tested our bottled Reverse Osmosis water and the PH was approx 4.5 our Royal Berkey with the Alkalizing Stones had a PH of almost 7. We couldn't be happier and only wished we would have picked one up along time ago! Thanks for all your help and education Scott.
