Product review (2 stars): Have used this filter for 13+ years...
... ever since the refrigerator was purchased.  It gets replaced every 6 to 10 months depending on how much work the local water company has been doing on the lines.  (Their work always fills the filters fast)  It has always been very dependable... works great, water and ice taste clean and fresh, no crack issues, easy install and replacement.

  I just ordered a replacement and I am very leery of this one.  Although the filter itself was sealed in plastic wrap, the product box/package itself was cut down apparently to fit the filter. If it was the proper filter and packaging, no alterations to the package would have been necessary. The fact that the filter itself was in plastic wrap was not reassuring as  anyone can seal anything in plastic with the right equipment.  I have a suspicion that this is NOT the same as the original one I have been purchasing all along and $40 (cost plus shipping) is a lot of money to waste on something I have no trust in.  I will not be purchasing from this seller again.
