Product review (1 stars): Inferior Product - Buy the Original Equipment Manufacture
After having this product installed for three months in the ice maker and testing the water for Total Dissolved Solids (TDS), I can report that there was absolutely no difference between the TDS for the water coming from the City to the water making up the ice.  In other words, this is an inferior product and I would not suggest purchasing it.  Bottom line is, it doesn't filter the TDS out of the water the way it is supposed to.  You are better off to purchase the Original Equipment Manufacture, or in my case LG filters made for the ice maker filter.  That's exactly what I have done for future filters.  They cost twice as much but do filter the TDS to a reasonable expectation.
