Product review (4 stars): An exact replacement in my LG
The filter is an exact replacement for the factory unit and is working as advertised. So easy to install. Remove the old one with a counter clockwise turn to the stop and pull out. I had only a few drops of waters escape. Insert the new one and turn clockwise to the stop, about 1/2 turn, you may hear the water surge into the filter.

The filtering agent is charcoal so run several tea glasses of water through before you drink. You will see a slight grey tint to the water at first. That is any charcoal dust that was present. By the third glass I was getting perfectly clear and completely tasteless drinking water. I am buying several more backups.
