Product review (1 stars): Out of date if package says "PUR" on the side.
This is our second order. I just tried to return it but I'm not able to. I try to buy things like this ahead, so I bought these in November while they were on sale at $10 off. The first package of two were great. It's the first filter in the new package of two that creates very malodorous water. I called whirlpool customer service, but they said the new filters are no longer made by PUR and that these filters are quite old/out of date. Of this second package, I'm disappointed with the first filter. Have not tried the second because I was planning on returning them. Installed in our fridge, the filter is used to remove potential toxins etc, but our drinking water from the tap tastes fine. With this filter just replaced the water smells horrible. After I put in the new filter, I flushed 4 gallons of water through it as the instructions say to do. I then made some coffee and thought there was a problem with our coffee pot. It is a coffee pot we bought a few months ago so the smell of the coffee was fresh in my mind. Because of this water filter, the water has a smell that is just like the burnt/electronic smell that you notice in the first pot of coffee made in a new drip coffee pot. That's the best way to describe it.  Whirlpool was apparently having issues with quality control and no longer has the filters made through PUR. The Whirlpool representative said nothing in the filter should smell the way I described, but confirmed that the filter is quite old if it says "PUR" on the side.
