Product review (2 stars): Nothing to write home about
I used this WSS-1 filter to replace the overpriced Samsung water filter in my refrigerator.  Installation was easy.  As others mentioned, the water dispenser did leak for about a day.  In the first day, when you would use the water dispenser, the "nozzle" on the door would drip for about 30 seconds after you got your glass of water.  Fortunately, the dripping quit after the first day.

I had a turbidity meter (measures particles in the water by parts per million) in the house so I thought I'd see how well this filter did.

Results:

House Water directly from the tap = 226 ppm
Water from the WSS-1 filter = 176 ppm
Water from my reverse osmosis undersink filter 17ppm (yes, only seventeen ppm)

So, the WSS-1 doesn't filter too much, if you really want a filter, go with a reverse osmosis type.
