Product review (1 stars): Do not buy unless directly from GE
If the filter is new and directly from GE, it works great and produces wonderful tasting water. However, the 3 pack that I purchased from a third party were all defective. Within a week the water from the first one started tasting as though it was no longer filtered. So I requested and received a refund for it. The second one lasted about a month and the third about 2 months. Each should last about 6 months. Don't waste your money on third party vendors that offer a better price because the product they offer could be defective.
