Yes, but it would be “overkill”. The purpose of the RS2 filter is to pre-filter the water before it hits the CB3. The RS2 is designed to get the “chunky” stuff out so that the useful life of the CB3 is maximized (the CB3 is more expensive than the RS2). You also might want to consider a GAC1 or a CB1 in front of the CB3. These do a good job also and are less money. Top 5.
