Product review (5 stars): Samsung Filter
I live in a town where the water company supplies well water so a filter is a must.  In two years time they are converting to lake water.  This filter retails for $55 and sells here for $36.  Great deal -- NO.  I found one recommended by Amazon (after  the Samsung was delivered) for $18.99 made by Waterfall Filter Company and one for $13.99 made by Refresh.  Both of these third party filters have excellent reviews.
