Product review (1 stars): Skip it
I will preface this review by saying that we have very hard water in our area.  That said, this filter wasn't up to the task.
Our Samsung 'fridge made a humming sound when you used the in door water - never did that with the Samsung filters.  The water had white "floaters".  It  tasted ok when you first drank the water, but if the water sat in your glass for longer than 10 minutes it tasted like chlorine.
Followed all the directions upon installation - ran several gallons of water thru it before drinking.  Used this for 2 days before we broke down and purchased the Samsung filter to replace this one.  Will never again stray from the Samsung brand. Yeah it costs more, but we wasted $20 on this only to throw it away after 2 days!
