Product review (1 stars): Unless you enjoy mopping don't waste your money.
The Amazon site shows a filter that appears to be equivalent to Samsung DA29-000-20B.  It is not.  I installed one of these filters in my Samsung refrigerator and it seemed to work perfectly--until a few days later when puddles appeared on the kitchen floor.  Finding no apparent problem, I called a repairman who found ice buildup in the back of the middle drawer but could not find the cause.  A day or two later the water problem returned.  I finally thought to check the filter.  The problem is that this filter is not what is depicted on Amazon's website, the hole in the filter being two or three times the size of the hole in the original Samsung filter.  The filter will seem to fit but unless you enjoy mopping the kitchen floor you had best just buy a Samsung filter.  Below is the Tier 1 filter.  Note the size of the hole and compare it to the smaller hole shown on Amazon's website.
