What is a CTO Plus filter?
We tested a drinking water size cartridge that we use a lot in countertop filters, undersink filters, garden hose filters, and as a reverse osmosis postfilter. It’s a sub-micron standard coconut shell carbon block, the MatriKX CTO Plus, that the manufacturer recommends for chlorine and VOC reduction but not for chloramine treatment. The CTO Plus is made with standard carbon, not catalytic. (Catalytic carbon is filter carbon that has been specially processed to enhance the properties that affect reduction of contaminants like iron, hydrogen sulfide, and chloramines.) We tested the CTO Plus at different flow rates to check the effect of residence time on chloramine removal. The result:
