Product review (2 stars): Does Not Filter Water As Much As Expected
We bought a Kenmore refrigerator and purchased this filter for it.  We measured our tap water at 351 Total Dissolved Solids (TDS).  The filter brought the number down to 286 TDS, so it filtered only 65 TDS.  The ZeroWater filter brings the TDS number down to zero.  Granted, filters other than ZeroWater are not expected to bring the number all the way down to zero, as this is what ZeroWater is known for and the basis on which they sell their products (but they don't make filters for refrigerators).  However, I don't know whether the number by which the Kenmore filter brings down the TDS measurement is reasonable or not based on the type of filter it is?  I would have expected more filtration than that, and for the amount it did filter I think this filter is overpriced.  Having said that, the taste of the water coming out of the fridge dispenser is OK.
