Product review (1 stars): Falls out of housing regardless of how tightly it's secured. Flooded fridge.
I bought this to replace our LG refrigerator water filter. We use filter # 5231JA2002A. The first time I tried installing it, I didn't get the filter attached in its housing correctly, but I didn't realize it, and woke up to a flooded fridge and a damaged wood kitchen floor. After mopping up, I tried reinstalling. This time I pushed the filter up into its housing much more firmly and it felt like it was installed correctly. (I pressed it upward until I felt a soft click into place, then rotated it into the lock position.) But the filter fell out of its housing again. I had a bowl under it this time so I didn't have a huge flood to dry up, but I was surprised the filter fell this second time. Then my husband installed it -- same process, and he also felt he had the thing in there correctly but it fell out again. I'm returning this. Either it flat-out doesn't fit correctly, or it's so difficult to install the right way that you can't tell if you've got a tight seal or if you're going to face a wet mess. Poor design and/or incorrect labeling for the filter item number.
