Product review (3 stars): The chips on these filters must be on a timer ...
The chips on these filters must be on a timer, not the amount of water used. It is just my wife and I and we hardly used refrigerator water. After replacing the filter with a chipped filter, we were away for 4 of the six months. When we returned, the filter read that it need to be replaced. We have been reading that the filter is expired 99 days ago for 6 months in the filter is still working properly.  Don't give GE your money.
