I bought the counter depth refrigerator in November.  In the spring I tried to replace the air filter.  The air filter from the factory was removed from the frame and shoved into the filter holder, breaking it.  The factory air filter was square and the holder was rhombus shaped.  I was sent a new filter holder, but it will not mount to the refrigerator.  The filter feature is useless.  My refrigerator has no filters available for it.  How does something like this even happen with a major appliance company?
