Bought filter HAF-CIN one day ago, I installed the new filter and after few minutes water all over . I removed that filter and installed the second one in the package and water again on the floor, inside the drawers and dripping from the side of the bottom drawer, two hours to dry all the water. My refrigerator is only 4 years old, I always bought original filter, I didn't know what else  to do. I removed the second new filter and installed the old filter back and no more water leaking.  I guess I need to keep the old filter on forever, unless you guys have a logical explanation for this.
