Does anyone know what the difference is between the R -2C replacement cartridge and the R-2 cartridge replacement?

I am looking at boxes for both products. The R-2C says Chlorine 91%. The R-7 says 97%.

How to know when to change filter

The R2 ESSENTIALS filter should be changed every 200 gallons or 3 Months whichever comes first. Or when there is a noticeable decline in flow rate or an increase in unwanted taste and odor based on your water conditions.
