Product review (1 stars): My refrigerator water started tasting weird due to this filter after 1 month.
Based on internet searches, I assumed it was my water reservoir tank in my 14 year old refrigerator causing my water to taste bad.  After a few hour of research I order the reservoir tubing and replaced it in my fridge only to discover I still had the issue.  I was about to begin the process of replacing all the water tubing in my fridge before I luckily came across a poor review blaming this filter for poor tasting water.  Since this filter was only a month old, I never assumed this could be the problem.  So after 75 dollar reservoir and hours wasted trying to figure out how to solve this issue, all i needed to do was replace a filter that only lasted a month.  Mad, but relieved I figured out the issue, I decided to call whirlpool to see if they would replace this 1 month old filter.  The lady at whirlpool was extremely rude and would not send me another filter not even consider maybe sending a couple of filters to compensate for unnecessary expenses due to their bad product.  Luckily, amazon replaced the filter for me.  First off, this filter should cost half as much as it does and 2nd, whirlpool should make customers happy especially when they have a 14 year old refrigerator and will be in the market for a new one very soon.
