Need to change my carbon filter, do these come in different levels of quality or is the standard carbon filter good enough?

Different suppliers, what you want to be sure to get is the right micron sizes pores to filter out chlorine and whatever else they are supposed to remove before the water gets to the ro membrane. Different RO set ups have one or two carbon filters before the membrane.
