Product review (5 stars): Samsung compatible
This worked great with our Samsung Refrigerator.
At first it did not seem like they would work as no water came out after removing the old OEM filter and replacing with this EcoAqua filter. I discovered that sometimes you need to hold the water button down for as long as 5 minutes to get it to work (and even let it sit for 30 minutes or so).  This same issue happened with a OEM Samsung filter.  Not sure what causes the issue.  I called Samsung customer service which is how I figured out this solution.  They said it just happens sometimes.  The 2nd EcoAqua filter worked immediately.
