Product review (4 stars): Slightly longer than LT800p but still works
Used this as a replacement filter for LG fridge to replace factory LT800p.  At first I thought it wouldn't fit. I installed it and it's just a bit longer than the factory filter.  The factory filter sits up inside a cutout inside the top wall. This would not fit into that cutout but there is plenty of space still left inside the flip down plastic shield.  Just close the sheild and it still works without leakage.  Just installed, no reference as to how well it work vs factory item.
