Product review (1 stars): A complete dud--kept popping out
I don't automatically feel the need to buy OEM replacement parts if others are available that work as well. However, this filter is a complete disappointment. Instead of snapping in as the LG filters do, this one simply wouldn't seat in the filter compartment and kept popping out. I tried closing the compartment with it in there, thinking maybe it would seat anyway, but then the water dispenser in the door didn't work. So out it came, the old, spent one went back in, and I've just ordered three LG filters on another site that has a much better price. It's possible that shaving down the flanges might have helped, but I have neither the time nor expertise to tweak it.
