Replace every six months. Seems extremely expensive
Within the last year this product has changed packaging, increased the price by about $20, and does not last as long as it used to. I have no choice but to use this product as it is the only one made for my particular refrigerator. Also, the company no longer offers a double pack, which would allow me to buy two at a time for a lesser unit price. I find myself having to purchase the product more often as my refrigerator notifies me that I need to replace the filter more frequently than before these changes. So I am stuck buying one unit at a time for $20 more and I need to purchase them more frequently, which only adds to the inconvenience and expense. Although the product works, I am highly dissatisfied with all of these changes.
easy to install now water tastes great again.
