I love my refreshment jug but the filter that came with the jug has lasted a long time (3 months minimum) but having already replaced it twice, I have found that the replacement filters do not last long . I had to replace the first replacement after 30 days and have just tested the new filter I installed and it is already showing a low pH of 8 (light blue). Originally it was a high 9 (nice purple with Ph drops) with the very first filter in the then new pot. I am disappointed that these replacement filters do not appear to be of the same quality as the first filter.
