The Pura 41407002 QCRO Quick Change Carbon Block Filter is the replacement carbon prefilter for the Pura QCRO and QCUF systems. It is a 5 micron carbon block and reduces chlorine, taste and odor to protect the membrane and give you better tasting drinking water.
Our water began tasting very bad again after about 9 months since the system was installed. We installed the 2 new filters yesterday and the water returned to the very good taste with the very first gallon from the system. We did NOT find any carbon residue in the first water from these two new filters like we usually do with standard carbon filters. Score - 10 for 10.
