Product review (5 stars): Do the math and for a couple pennies a day you know what you're getting.
I simply don't understand why people spend a little less money on the knock offs. I've read with most of them there are problems with not fitting well and if one considers that these last for six months the extra cost per day is miniscule. These always fit my Samsung refrigerator and perform beautifully. They also come with a document showing precisely what chemicals and the percentages this filter cleans for you. That's not true with many of the knock offs. You don't know what kind of quality your getting with the others and clearness of the water is not a method of determining a filters effectiveness.
