Product review (1 stars): Replacement filter does not fit in refrigerator exactly in order to operate properly.
This #2 filter does not work - it will not properly lock into the housing and water service is intermittent.  I am on my 3rd "white" EveryDrop filter in just a couple weeks, and each one has been problematic.  The previous "blue" version (and filters made by PUR) never had any issues over the past 7 years we've had our Kitchen-Aid refrigerator.
There is not an issue with our water supply, because when I eject the filter, the water dispenses perfectly.
This is a known issue at Whirlpool and the only solution they offer is to send out a technician for big bucks, instead of figuring out how to make these filters properly...
