Amazing 70,000 gallon chlorine capacity and great chemical removal properties. Our most popular cartridge.(Formerly MatriKX +1.)
The MatriKX CTO Plus, formerly called KX-1, is the top of the line in standard carbon blocks. A tight nominal 0.6 micron block that is often called "the chlorine guzzler." As its name indicates, it is a “Chlorine/Taste/Odor” filter, plus a top performing chemical remover. It has a chloroform reduction capacity of 1,700 gallons, which indicates that it will remove virtually any chemical contaminant.
