Product review (1 stars): Two out of two did not work
Decided to give these a try and it was time to change the filter today.  I tried the first one and when I inserted it I did not hear the normal air release that normally you hear after the new filter is installed.  I tried the water dispenser and no water.  I reinserted the filter several times, no water.  I tried the other filter in the package with the same result, no water.  I reinstalled the old filter and the water ran again.  The filters look the same except for the color but don't work.  Now I am stuck. My old filter is a old style blue 4396841 fast fill, the new one was suppose to be a direct replacement. I will try and call for technical assistance and update.
UPDATE:  So I contacted Amazon and they looked into the matter and arranged for a refund.  Very good customer service. Just had to send the filters back and they provided a return label. They recommended I contact the vendor, which I did and all were in agreement that the filters were defective.  I tried a different vendor filter this morning and the new filters worked as advertised.  Still wondering how a filter can be defective unless there was some manufacturing defect in this batch of filters.  I will never know because I don't see myself trying the newer version again.
