Product review (5 stars): BEST PRICING I CAN FIND FOR THESE FILTERS
I sure wish that I had researched better before buying my Samsung refrigerator and found that this product used to filter the water was so expensive.  I have been paying so much more at Lowe's that when I searched and found them for less at Amazon.com, I was thrilled.  My refrigerator tells me to replay the filter every 90 days by flashing the light that it is time to replace the filter.  It doesn't matter if we use the refrigerator dispenser or not!  We usually only replace them every 5-6 months since we assume that the "timing" is for a family of 4 when there is only the 2 of us.  I have friends that have filters that only need replacing once a year and don't cost any more than these filters.  I sure learned my lesson for my next refrigerator search and that is to check the cost of the "replacement items" and the frequency that these items are to be replaced.
