Kx Technologies MATRIKX brand carbon blocks are the most trusted and widely used carbon blocks in the world. The 10” size is the industry standard and will fit our systems, as well as virtually every brand of RO system that use similar looking carbon blocks and the 20″ size works in our legacy BRS Spartan unit along with other 20″ RO systems.
Most common filter arrangements
- If your system utilizes one carbon block we recommend installing the 5 Micron CTO in the second stage after your sediment filter.*
- If your system utilizes two carbon blocks, we recommend installing the 5 micron CTO in the second stage after your sediment filter and the 1 micron CTO Plus in the third stage.
Available in 10″ and 20″
*You may use a 1 micron CTO PLUS in a single block arrangement, however, depending on pre-filtration and sediment content of your home’s water, it may clog faster than you would like.
