Product review (5 stars): Super easy filter change
I purchased this filter for my 4 French door Samsung refrigerator model RF4289HARS. Installation is really quick, you just have to unscrew the old one about a half a turn to the left and it comes right out and install the new one with half a turn to the right. Then run about a gallon of water out of the water dispenser in the door to remove any air from the line, and finally press  and hold the filter reset/ child lock button on the front of the display for about 3-5 seconds and you're done!
