Product review (3 stars): The same part number, but something has changed
I ordered two of these filters and LG must have made some change to these filters.  The first one I installed leaked in the refrigerator and the first few quarts of water from the dispenser were grey and cloudy.  I installed the second filter and it did not leak, but the water was still grey and cloudy.  It eventually cleared up, but I have not had this happen before.  I have replaced these filters regularly and never had this problem.  It also seems that the water pressure from the dispenser is higher and splashes out of the glass if you are not careful.  This must be a new design or manufacturer, and I don't like them.
