I installed the new system filter after the first wash, I have found a deposit on the glasses. so I kept the internal filter of the new system but cons I handed the old external filter and I remade several dishes from ... more problem. why sell a set while the inner filter is deteriorating, the other (bigger) does not move with time. more external filter is not quite the same color but appears to be similar to the old. In any case putting it, the dishes are not impeccable. We must therefore put the former to have a good result.
