Product review (1 stars): IS NOT A TRUE FILTER REPLACEMENT----IT IS A CHEAP KNOCK OFF THAT DOES NOT WORK ---DON'T WASTE YOUR MONEY!!
Don't waste your money on this filter.  It is not the same as an original filter for a DA29-00020B.  The filter hole is larger and therefore the filter does not work properly.  I found that it caused my water spicket to leak and drip.  I thought I was getting a great deal, but the old saying that is it sounds too good to be true, it probably is.  This is a cheap knock off, but again, it is not the exact same filter.  I am returning it immediately----it does not work.
