I purchased a genuine replacement filter using the Samsung Subscription Service. The filter replacement seemed easy enough...unscrew the old filter and screw in the new filter. I did this in the evening and at the time everything seemed ok. I woke up the next morning and my kitchen AND Basement was flooded. Several thousands of dollars in damage. When I removed the new filter I installed I could tell the water was dripping from the plunger/nozzle on the filter housing. Not enough to give any warning at the time of the replacement of the filter. As evident with the numerous bad reviews there seems to be a design flaw or just plain bad engineering with the filtration system. I would highly recommend staying away from Samsung Refrigerators.
